Bugs/5.01CD

Gh78: more cleaning up of my two entries to avoid sentences running beyond the length of the screen

1) The ext2 persistent home bug (ext2 partitions not recognized properly)
is still not fixed in 5.01, because of a a typo in the knoppix-autoconfig file:
wrong: ext3|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;;
correct: ext2|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;;
Please find a diff in here:
http://s94002264.onlinehome.us/grub/knoppix-autoconfig.diff
BTW, I found a work around fix, cf:
http://www.knoppix.net/forum/viewtopic.php?p=103883#103883
Gilles van Ruymbeke

2)knoppix splash cheatcode doesn't work, it worked with 4.0.2 version.

3)difficulty to boot on some (recent) laptop: needs to use noudev and sometimes
nompcmcia to start, but Konsole failed start, complain that no tty are available.
WORKAROUND: On a PB laptop, I manage to start without passing noudev, progress bar of autoconfiguring devices don't stop but by key pressing [CTRL c] twice, boot process continue.
After an HD install, need to put rt2500usb in blacklist

4)boot process is horribly slow if a pci card with rt2500 WLAN chipset is plugged
and failed on DHCP request, no problem on Cebit 5.0: card is well recognise.

5)printing impossible (report from forums.knoppix-fr.org)

6)module compilation is not possible (out of the box), have to have a look deeply
(maybe problem with header or some links to them)
Some more info: This is probably related with the Debian [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=368544 bug #368544] as the parts missing
in the headers are those supposed to be in a newcomer linux-kbuild package

7)[INSTALL] mount with removable media,
"Please change the -u knoppix and -g knoppix in
/etc/udev/knoppix.rules, either to match the "primary user", or just
remove them."

8) CD-Burning with an external USB device is broken.
as i posted in the forum http://www.knoppix.net/forum/viewtopic.php?t=24784
there are some messages from cdrecord in the k3b failure report
about missing entrys in /dev one of them about /dev/sg0 ...
i looked for what was there in 4.0.2CD and found this:

after creating /dev/sg0 with mknod ( using mknod without beeing absolutely sure
what you are doing can lead to deleting all your data on harddisk or even worse )
at least k3b simulation started working ...
i will do a real burning test later ...

9) ipw2200 v1.1.1 (the one in kernel 2.6.17) relies on firmware 3.0 while
the Knoppix package ipw2200-nonfree only contain older firmwares.
Please update ipw2200-nonfree, cf
http://ipw2200.sourceforge.net/firmware.php

10) Setting the timezone does not work. KDE's time applet requires the root
password (should probably use ksudo instead).
Workaround: sudo vi /etc/timezone,
sudo cp /usr/share/zoneinfo/Continent/City /etc/zoneinfo.

11) Mounting of a PCMCIA flash drive works only once. After remove/insert of the card,
the following error message appears: "mount:Gerätedatei /dev/hde1 existiert nicht" (rol).

12) Improvement: the CD and DVD editions miss the p7zip package.
If you compress a tar archive of the Knoppix root filesystem, the result
is 20% smaller than the one produced by bzip2. Definitely useful!

13) Improvement: the CD and DVD editions miss the ccache package
(102 KB install size). This compiler cache is the best way to recompile
big projects (like the Linux kernel) in a much faster way.

14) To use SD cards it currently is necessary to manually ''modprobe mmc_block''.

15) Improvement: If possible include new ''ipw3945'' WLAN module.

16) I use a working CD (tested on other computers). On my computer, Knoppix stops
with the message "can't find KNOPPIX filesystem, sorry, dropping you to a (very
limited) shell..", just as the bug 15 of Knoppix 5.0DVD. Anyway the boot option
nodma does not make things work. I have found no workaround. I have got a SATA
CDROM/DVD drive (Plextor 712SA).
16b?) Can't burn, and DVD-reader access are very slow on laptop with ICH6 SATA controler
Workaround (after HD install):

''echo "options libata atapi_enabled=1" > /etc/modprobe.d/libata''

''mkinitramfs -o /boot/initrd.img-2.6.17-test''

Then modify your boot config (/boot/grub/menu.lst for grub) to adapt your initrd like:
''initrd /boot/initrd.img-2.6.17-test''

And add to your kernel options (append):

''ide1=noprobe''

17) X won't work on some systems when using Knoppix CD 5 or Knoppix CD 4.
Tried on five different systems, three notebooks, two desktop systems,
but xorg's X failed to start and complained about missing files. Integrity
of CD tested and okay.

18) In KNOPPIX_V5.0.1CD-2006-06-01-DE.iso (MD5 checked OK) *boot/isolinux/isolinux.bin
is corrupt or hash is wrong in md5sums file.

19) Apache2 returns "Partial Content" when accessing a local (127.0.0.1) page.
Small files works, larger files (> Mtu ??) not.
See http://www.knoppix.net/forum/viewtopic.php?t=25639

20)(may be the same as 1): Knoppix 5.0.1, English CD download, failed to mount the hard drives on a Dell Dimension 5100, which has a second SATA hard drive installed for backup. It worked fine if I disabled the second hard drive from the BIOS setup.
James Wimberley 9/10/2006

21) (same as 3): Knoppix 5.0.1, English CD download, failed to boot on an HP Pavilion zv5120us laptop, unmodified except for extra memory. The hangup was on the fourth line, "looking for CD in /dev/hdc". Knoppix 4.0 boots fine on the same machine. The copy of 5.0.1 should be OK as it boots on the Dell, see 20.
James Wimberley 9/10/2006

22) The !cal command does not work in a continuous manner. In fact it works about
40% - 60% of the time when done consecutively. !ls and !top work without issue, but
there seems to be a glitch in the !cal command when using the Knoppix 5.0.1 CD.

23) Notebook IBM Thinkpad T40: ipw2200 does not work due wlan-card firmware upload failure.

24) The persistent home bug: i have hdd with 2 partitions (hda1 - ntfs, hda5 - fat32). if on both partitions file knoppix.img exists, but on hda1 this file is broken(all zero) - then i can't use /dev/hda5/knoppix.img too due knoppix-autoconfig error: wenn one file was found, but broken, script will skip all other knoppix.img.

25) in autoconfig-script es is not enough fehler messages (knoppix-image: no message by broken(zero) file knoppix.img)

26) the KDE internet modem dialer, 'kppp', appears to be broken,
and can't find my serial modem, even when running as root.
A partial solution is to use the ?debian? 'pon' , 'pof' and 'pppconfig' scripts
from the shell. --[[User:gh78|gh78]]

26) The touchpad bugs are still there.
Double clicks and 'dragging' don't register on my dell latitude touchpad.
The solution is to pass 'psmouse.proto=imps' to the kernel.
This can be done at the CD cheatcode prompt.
It would be nice if it was programmed in by default. --[[User:gh78|gh78]]

Gh78: 5.01 update

2006-11-27 Mon 11:30:57 PM
I am heartened by the changes in 5.01CD. I've figured out how to fix the modem issue, and gpm works again in mc. now if only it would work in the curses shell scripts...
I am happy to see my airlink usb ethernet adapter is automatically detected, and Xorg's improved monitor support is much appreciated.

Thu Apr 13 00:41:00 PDT 2006

Hello.

I am a kinda beginner--a bit more advanced than a newbie.
I started with v3.3, then moved to v3.4 [thanks for the cd, kyle] then used v3.7, 3.81, 4.02.
I also try D.S.L. from time to time. [a v3.4 fork]
I'm interested in [http://freshmeat.net/projects/twin/ twin] and would love to see it on a cd.

I am saddened to see the lack of the 2.4 kernel--everything seemed to work much better back then.

I am quite happy to see the wiki working. open source *depends* on feedback from the users.

have a nice day

9) ipw2200 v1.1.1 (the one in kernel 2.6.17) relies on firmware 3.0 while
the Knoppix package ipw2200-nonfree only contain older firmwares.
Please update ipw2200-nonfree, cf
http://ipw2200.sourceforge.net/firmware.php

10) Setting the timezone does not work. KDE's time applet requires the root
password (should probably use ksudo instead).
Workaround: sudo vi /etc/timezone,
sudo cp /usr/share/zoneinfo/Continent/City /etc/zoneinfo.

11) Mounting of a PCMCIA flash drive works only once. After remove/insert of the card,
the following error message appears: "mount:Gerätedatei /dev/hde1 existiert nicht" (rol).

12) Improvement: the CD and DVD editions miss the p7zip package.
If you compress a tar archive of the Knoppix root filesystem, the result
is 20% smaller than the one produced by bzip2. Definitely useful!

13) Improvement: the CD and DVD editions miss the ccache package
(102 KB install size). This compiler cache is the best way to recompile
big projects (like the Linux kernel) in a much faster way.

14) To use SD cards it currently is necessary to manually ''modprobe mmc_block''.

15) Improvement: If possible include new ''ipw3945'' WLAN module.

16) I use a working CD (tested on other computers). On my computer, Knoppix stops
with the message "can't find KNOPPIX filesystem, sorry, dropping you to a (very
limited) shell..", just as the bug 15 of Knoppix 5.0DVD. Anyway the boot option
nodma does not make things work. I have found no workaround. I have got a SATA
CDROM/DVD drive (Plextor 712SA).
16b?) Can't burn, and DVD-reader access are very slow on laptop with ICH6 SATA controler
Workaround (after HD install):

''echo "options libata atapi_enabled=1" > /etc/modprobe.d/libata''

''mkinitramfs -o /boot/initrd.img-2.6.17-test''

Then modify your boot config (/boot/grub/menu.lst for grub) to adapt your initrd like:
''initrd /boot/initrd.img-2.6.17-test''

And add to your kernel options (append):

''ide1=noprobe''

17) X won't work on some systems when using Knoppix CD 5 or Knoppix CD 4.
Tried on five different systems, three notebooks, two desktop systems,
but xorg's X failed to start and complained about missing files. Integrity
of CD tested and okay.

18) In KNOPPIX_V5.0.1CD-2006-06-01-DE.iso (MD5 checked OK) *boot/isolinux/isolinux.bin
is corrupt or hash is wrong in md5sums file.

19) Apache2 returns "Partial Content" when accessing a local (127.0.0.1) page.
Small files works, larger files (> Mtu ??) not.
See http://www.knoppix.net/forum/viewtopic.php?t=25639

20)(may be the same as 1): Knoppix 5.0.1, English CD download, failed to mount the hard drives on a Dell Dimension 5100, which has a second SATA hard drive installed for backup. It worked fine if I disabled the second hard drive from the BIOS setup.
James Wimberley 9/10/2006

21) (same as 3): Knoppix 5.0.1, English CD download, failed to boot on an HP Pavilion zv5120us laptop, unmodified except for extra memory. The hangup was on the fourth line, "looking for CD in /dev/hdc". Knoppix 4.0 boots fine on the same machine. The copy of 5.0.1 should be OK as it boots on the Dell, see 20.
James Wimberley 9/10/2006

22) The !cal command does not work in a continuous manner. In fact it works about
40% - 60% of the time when done consecutively. !ls and !top work without issue, but
there seems to be a glitch in the !cal command when using the Knoppix 5.0.1 CD.

23) Notebook IBM Thinkpad T40: ipw2200 does not work due wlan-card firmware upload failure.

24) The persistent home bug: i have hdd with 2 partitions (hda1 - ntfs, hda5 - fat32). if on both partitions file knoppix.img exists, but on hda1 this file is broken(all zero) - then i can't use /dev/hda5/knoppix.img too due knoppix-autoconfig error: wenn one file was found, but broken, script will skip all other knoppix.img.

25) in autoconfig-script es is not enough fehler messages (knoppix-image: no message by broken(zero) file knoppix.img)

26) the KDE internet modem dialer, 'kppp', appears to be broken,
and can't find my serial modem, even when running as root.
A partial solution is to use the ?debian? 'pon' , 'pof' and 'pppconfig' scripts
from the shell.

26) The touchpad bug is still there--double clicks and 'dragging' don't register on my dell latitude touchpad.
The solution is to pass 'psmouse.proto=imps' to the kernel.
This can be done at the CD cheatcode prompt.
It would be nice if it was programmed in by default.

Gh78: KPPP bug, and working substitute program

1) The ext2 persistent home bug (ext2 partitions not recognized properly)
is still not fixed in 5.01, because of a a typo in the knoppix-autoconfig file:
wrong: ext3|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;;
correct: ext2|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;;
Please find a diff in here:

BTW, I found a work around fix, cf:

2)knoppix splash cheatcode doesn't work, it worked with 4.0.2 version.

3)difficulty to boot on some (recent) laptop: needs to use noudev and sometimes
nompcmcia to start, but Konsole failed start, complain that no tty are available.
WORKARUND: On a PB laptop, I manage to start without passing noudev, progress bar of autoconfiguring devices don't stop but by key pressing [CTRL c] twice, boot process continue.
After an HD install, need to put rt2500usb in blacklist

4)boot process is horribly slow if a pci card with rt2500 WLAN chipset is plugged
and failed on DHCP request, no problem on Cebit 5.0: card is well recognise.

5)printing impossible (report from forums.knoppix-fr.org)

6)module compilation is not possible (out of the box), have to have a look deeply
(maybe problem with header or some links to them)
Some more info: This is probably related with the Debian [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=368544 bug #368544] as the parts missing
in the headers are those supposed to be in a newcomer linux-kbuild package

Knoppix does the very best it can to automatically figure out what hardware the PC has & it does this without human intervention. DMA is a feature that speeds up data tranfer on IDE devices such as CDROM drive& HD drives. Some chipsets and/or harddiscs are broken or buggy. Using DMA would cause problems on such systems and in many many cases, if the CDROM drive does not support DMA then it fails to fully boot Knoppix from the CDR. DMA was enabled by default in Knoppix 3.4 through 3.7 and has been disabled in 3.8.x and up. To boot Knoppix 3.4 through 3.7 and get around this DMA problem, I boot knoppix with the following [[Cheat Codes]]:
knoppix nodma

If your system works properly with DMA, and you are booting from HD, you can enable it by typing "/sbin/hdparm -c3 -d1 -m16 -k1 /dev/hda" or by editing the "/etc/init.d/bootmisc.sh" startup script and uncommenting the hdparm -qd1 /dev/hda line to have it permanently on at reboot, if the line is not there add it.

A cleaner way to do it requires installing the hdparm package (use the command "apt-get install hdparm" to do this) and edit
the file "/etc/hdparm.conf".

==== File transfer between Knoppix and Windows: ====
===== Q: I see the partitions from my hard disk on the desktop and can access their contents when I click on them, but if I try to write to them I always get the error message "access denied". How can I write to my existing partitions? =====

A: The general philosophy of KNOPPIX is to allow as little write access as possible. For this reason, existing partitions are either not mounted or only mounted "read only". If you click with your right mouse button on an icon, the "read-only" attribute under item "device" can be un-checked. After this, the partition can be mounted "read-write" (for already mounted partitions, first click on "unmount"!). Alternatively, you can use the mount command to make the drive read/write, see '''man mount''' for details. '''CAUTION:''' writing to NTFS partitions can lead to data loss, since Linux does not really support this file system! However, DOS and FAT32 file systems are safe for write access. Tip: In the shell the command "mount -o remount,rw /mnt/" can allow already-mounted file systems to be "made writeable".

=====Q: How can I write data on NTFS partitions?=====

A: Under most conditions, Knoppix can not write or change files on an [http://www.wikipedia.org/wiki/NTFS NTFS] partition. Forcing it to do so may end up scrambling the underlying NTFS filesystem. Knoppix (and the Linux kernel) can read NTFS partitions just fine, the danger is only present when attempting to write to it. Older versions of Knoppix included a program called [http://www.jankratochvil.net/project/captive/ Captive NTFS] that used the existing NTFS drivers from a Windows system to acesss the NTFS drive. Even then it was slow and unstable. [http://www.jankratochvil.net/project/captive/ Captive NTFS] has not been maintained for over a year and is not currently included in recent Knoppix versions.

=====Q: How do I access files created in Knoppix with other operating systems? =====

A:
*'''Windows NT, XP (NTFS) and Windows 95, 98'''
*:* Use a [http://www.wikipedia.org/wiki/keydrive keydrive].
*::* Boot Knoppix with keydrive installed, Knoppix will add a keydrive icon to the desktop
*::* By default, the keydrive is read only. Change to r/w with right mouse button click -> Actions -> Change Read/Write mode -> click yes to make writable.
*::* the files you save on the key drive are then readable by windows.
*:* Use a floppy ?
*:* Use a CD writable ?
*:* Is a Knoppix partition readable by Windows XP (if I chose to install Knoppix on my hard drive)?

*'''Windows 95, 98'''
*:* Mount the file system in Knoppix and write to the hard drive, see above
*:* Is a Knoppix partition readable by Windows 95 or 98 ?

=====Q: I want to copy files to a windows box over the network=====
A:

* First method
I boot with Knoppix from the CD drive. Once it has fully loaded to the KDE desktop, I open a konsole command window. I assume the the hda1 (C: drive) is a FAT32 drive, so I mount it with the command:
sudo mount -t vfat -o ro,users /dev/hda1 /mnt/hda1

If instead the the hda1 (C: drive) is a NTFS drive, the I mount it with the command:
sudo mount -t ntfs -o ro,users /dev/hda1 /mnt/hda1

Next I open up the GUI file manager (called konqueror).
sudo konqueror
Once that comes up, in the location bar, I use the following to authenticate to a Windows domain & then access a windows networking share.In the location bar:
smb:/domain\username@IP.address.of.machine
If you do not need to authenticate to a domain, the form is:
smb:/hostname
or
smb:/IP.address.of.machine

This allows me to access windows shares. I navigate to where I want to save the data, then hit the keys CTRL-T to open a tnew tabbed window. Then in that location bar type:
/mnt/hda1/
Now I see the hda1 (C: drive) contents. Just like in windows explorer, select the file & folders you want to copy, CTRL-C or right-click & copy them. Use the mouse & move over to the other tab with the smb connection, then CTRL-V or right-click paste to initiate the transfer. When you are done copying files, close the konqueror window, click the KDE K menu and choose to reboot/shutdown the PC. TO shutdown the PC by command:
sudo init 0

* Other method, in which both directions are possible. Either start SAMBA or mount the remote share.
** "sudo /etc/init.d/samba start", add users with "smbpasswd -a knoppix". After this, the home directory of user knoppix will be shared as readonly. If you need other shares, edit /etc/samba/smb.conf and restart samba (replace "start" with "restart").
** "mkdir tmp/share; sudo mount -t smbfs -o username=Administrator //otherbox/share /tmp/share" (maybe start samba too to get rid of the warnings, especialy when using "nmblookup")
* Or you can obtain a lissetup.sh ("wget <nowiki>http://users.volja.net/zejnovi/lissetup.sh</nowiki>" in console). After doing that, in console, type: "chmod +x lissetup.sh", and then "./lissetup.sh". After doing this, you can use the LAN browser in Konqueror.

==== Q: Knoppix 3.2: Errormessage during booting, when HOME-Directory is saved on HD? ====
I've saved the date on a FAT-32Partition, as an image and without password. I can't format the partition in a LINUX-Format, since it's used by other data. When I boot KNOPPIX with "knoppix myconfig=... home=....", a short time later the message appears, that s.th. is not found and I'm asked for a password with at least 20 signs length (but such a password does not exist). It's no difference whether I type "home=scan" or s.th. like "home=/dev/hda5". Never the less it seems to work fine, when I ignore the password request and negate the further enquiry with "n" for "no". When I leave out "home=..." Knoppix has forgotton -as expected- the Home-Directory. The behavior is some how unbeautiful. Does anyone know how to avoid the request of that password?

A: I encountered this problem when I placed both the config files and the persistent home on the same partition.If you do not have separate partitons then the config can be located on a floppy( I have not tried this.)

====Q: What is the root password?====

A: There is none; all passwords are locked/scrambled by default. You can set it by going Knoppix Menu->Root Shell and typing "passwd", then enterting a root password, also there are several sections you can read dealing with this subject in KNOPPIX/README_Security.txt.
You can also type "sudo su" or "sudo -s" in any console window, or use <ctr>-<alt>-F2 to get at the text console with already opened root shell.

However, in some older versions of Knoppix, if you type 'sudo -s', it will ask for a password. If you simply press return without entering anything, it will tell you 'Authentication Failed."

See also the forum thread titled [http://www.knoppix.net/forum/viewtopic.php?t=11500 "Root Password (what is it?)"]

====Q: How can I watch a DVD?====

A: First of all, you have to have Knoppix installed on your hard drive. You won't be able to execute the following proceedure if you are running it from the CD.

* Become root

* Add the following lines to your /etc/apt/sources.list:

deb <nowiki>http://www.videolan.org/pub/videolan/debian</nowiki> $(ARCH)/
deb-src <nowiki>http://www.videolan.org/pub/videolan/debian</nowiki> sources/

* Then do:

apt-get update
apt-get install libdvdcss2

* Play the DVD (e.g. with Xine, Ogle, Videolan, Mplayer etc).
* If your DVD plays but skips and jumps, then you probably need to enable Direct Memory Access (DMA) for the drive.
* To see if DMA is enabled, log in as root and type: "/sbin/hdparm -d <device name>" For example: "/sbin/hdparm -d /dev/hdc" It it says "using_dma = 1 (on)" it is already turned on.
* Otherwise, to enable DMA type: "/sbin/hdparm -d 1 /dev/hdc"
*If you want DMA to be enabled automatically then add the line "/sbin/hdparm -d 1 /dev/hdc" to any startup script (/etc/init.d/bootmisc.sh for example).
*Enjoy watching DVDs in Linux :-)

====Q: I've installed Knoppix to my HD and default language and keyboard setting is German. How do I change to US English? I've changed KDE by fumbling through what I remembered of KDE Control Center. The keyboard is still in German with some of the keys in different places.====

A: Right click on the German flag in the system tray of the taskbar, and choose configure from the menu and set the keyboard to the layout you want to use.

Alternatively, you can use KMenu > Settings > Control Panel > Regional & Accessibility > Country/ Region & Language > Locale > Country: "C - Default", Keyboard: English: US That does it for KDE.

For the rest of the system, as root, type '''dpkg-reconfigure locales'''. The first page is a list of fonts(?), press Tab then Enter to skip it. The second page asks "Which locale should be the default in the system environment?" -- choose one of the en_US options. ISO-8859-15 is nice
(it includes the Euro), although there is nothing wrong
with ISO-8859-1 (aka Latin1).

====Q: I've set the default language and keyboard in KDE, but some pages in Mozilla still come up in German instead of English. How do I fix this?====

A1: In Mozilla, under Edit > Preferences... and check on Language. On the right-hand side of the page you'll see that German is preferred over English in multi-lingual pages. Move English up and it will be the preferred language.

A2: In Firefox, select Edit > Preferences. Click the Advanced button, the General tab, then the Edit Languages button. As above, move a line marked "English" to the top.

====Q: I think about using Knoppix to make Partition-Images with [http://www.partimage.org partimage] - Did anybody try this out? Thanks in advance! -- http://linuxwiki.de/Brüßler====

A: Yes, it works. -- [http://linuxwiki.de/PartImage LinuxWiki PartImage (in German)]

====Q: How do I save my preferences (language, UI...) at the end of my session, when booting from CD? How do I restore them?====

Go to the K-menu > KNOPPIX > Configuration and choose "save config", you can save to floppy or to an already existing partition on the harddrive. (on a windows partition is fine)

To restore it, at the "boot:" prompt type in "knoppix myconfig=scan", and it should find and restore your saved settings at boot time.

====Q: After Installed knoopix in HD with lang=es, if I remove all the user configuration files in the /home/knoppix directory, the keys "< >" of my spanish keyboard are no longer recognized in the new kde session. What is the configuration file resposible of this behaviour?====

A: Check the small flag in the bottom right corner of the screen, and you have to boot up with lang=es as a kernel parameter for it to work. (check /etc/lilo.conf)

====Q:From where does KNOPPIX start all the scripts at the bootprocess?====

A:The init scripts are located in /etc/init.d and are [[symlink]]ed to
in the /etc/rcX.d directorys in a sysV like fashion.

====Q: Where can I find where all the boot-time parameters are interpreted???====

A:You can see them in /etc/init.d/knoppix-autoconfig script

====Q: How do I use an USB memory stick to save myconfiguration?====

A: First boot KNOPPIX with the [http://www.wikipedia.org/wiki/keydrive memory stick] inserted. Got to the KNOPPIX menu, Configuration, Save Configuration. When asked, choose /dev/sda1. When booting type '''knoppix myconf=scan home=scan''' at the boot prompt.

====Q: After using KNOPPIX, my Dell computer does not start!====

A: This is an issue with the Dell BIOS. Simply pull out the power cord from your computer for a few seconds, and your computer should start again. You can also try passing "apm=off" or "apm=real-mode-poweroff" to the kernel during startup. apm=real-mode-poweroff is better because it keeps other apm-features (advanced power managment) turned on.

====Q: How can I see a film with subtitles that of course I have, I think Xine is useful but I can't do it?====

A: in a console "xine name_movie.ext#subtitle:name_subtitle.ext" you have to replace .ext with the real extension

====Q: Which program do I use for word processing, spreadcheat calculations, image processing, burning, scanning, surfing, chatting...====

A: Take a look at the [http://www.eleli.de/knoppix/docs/tutorial/english Knoppix Tutorial.]

See also : * [http://www.linuxdevcenter.com/pub/a/linux/2003/11/20/knoppix.html?page=2 Using and Customizing Knoppix]

====Q: How do I stop the KNOPPIX web page from appearing every time I start KNOPPIX? ====

A: here is a 4 step process to edit your start up scrips so you get a clean desktop when you start your machine.

1.Become root: in konsole, type:
sudo bash

2. Delete link to read-only x-init file on cd. type:
rm /etc/X11/Xsession.d/45xsession

3. Open the /KNOPPIX/etc/X11/Xsession.d/45xsession file in kwrite. type:
kwrite /KNOPPIX/etc/X11/Xsession.d/45xsession

3.1 In kwrite, search for:
ln $HOME/Desktop/KNOPPIX.desktop $HOME/.kde/Autostart/showindex.desktop
by clicking on the magnifying icon below the main menubar.

3.2 below the line that reads:
ln $HOME/Desktop/KNOPPIX.desktop $HOME/.kde/Autostart/showindex.desktop

and above the line that reads:
fi
, insert:
#added by gh78 --this next line removes the autostart link
rm -f $HOME/.kde/Autostart/showindex.desktop
#added by gh78 --this next line removes the knoppix intro web page from your desktop as well
rm -f $HOME/Desktop/KNOPPIX.desktop

4. Save the x-init file as /etc/X11/Xsession.d/45xsession

done.

Now when you save your configuration, the /etc folder is saved as well--and your new startup script will now start without creating those files.

Cheat Codes

2006-05-21T00:06:24Z

Gh78: added 'boot=xxxx' cheat code

==== Introduction ====
German Version: [[Cheat Codes Deutsch]] / French Version: [[Cheat Codes French]] /
Versión español: [[Cheat Codes Spanish]]
----
'''Cheatcodes''' are used to pass options to KNOPPIX to help with getting it working on difficult hardware. You type them into the boot screen and press enter/return. The format is "kernel option option option ...". Usually "'''knoppix'''" is the right selection for the "kernel". You can type more than one cheatcode before pressing enter. Also note that some options can take on values.

Example: "knoppix xvrefresh=60 noscsi floppyconfig"

----

==== Options ====
;lang=bg|be|ch|cn|cs|cz|da|de|dk|es|fi|fr|ie|it|ja|nl|pl|ru|sk|tr|tw|uk|us : specify language/keyboard

: You can click on http://www.w3.org/WAI/ER/IG/ert/iso639.htm to see the two-letters code meanings.

: For example, typing knoppix lang=us you change the keyboard/language to US english.

: If you don't change the keyboard, in the default DE-bootimage, Knoppix boots with the [http://en.wikipedia.org/wiki/International_keyboard_layouts#Germany_and_Austria_.28but_not_Switzerland.29 german keyboard layout] (i.e. '=' letter is located at Shift-0 at this keyboard). Print the german keyboard layout for your reference.
 
;keyboard=us : specify only [[console]] keyboard
 
;xkeyboard=us : specify [[XFree86|X]] keyboard
 
;atapicd :Do NOT use SCSI-Emulation for IDE CD-Roms - Knoppix V3.4 and later
 
;desktop=[[fluxbox]]|[[icewm]]|[[larswm]]|[[twm]]|[[wmaker]]|[[xfce]] : Use specified WM instead of KDE
 
;screen=1280x1024 :Use specified Screen resolution for X
 
;xvrefresh=60 or vsync=60 : Use 60 Hz vertical refresh rate for X
 
;xhrefresh=80 or hsync=80 : Use 80 kHz horizontal refresh rate for X
 
;xserver=XFree86|XF86_SVGA : Use specified X-Server
 
;xmodule=ati|radeon|[[fbdev]]|vesa|savage|s3|nv|i810|mga|svga|tseng : Use specified XFree4-Module
 
;wheelmouse : The mouse is a wheelmouse - not needed since 2003-04-15
 
;nowheelmouse : Regular PS/2 mouse - 2003-04-15 and after.
 
;0 : Runlevel 0, Shutdown
;1 : Runlevel 1, Textmode, single user
;2 : Runlevel 2, Textmode only
;3 : Runlevel 3, Textmode only
;4 : Runlevel 4, Textmode only
;5 : Runlevel 5, Graphics mode, default
;6 : Runlevel 6, Reboot
 
;myconfig=scan or floppyconfig or floppyconf (in recent versions) : Run '''knoppix.sh''' from a floppy. The "floppyconfig" option allows you to reconfigure the system after autoconfig, or install your own config files, by mounting a floppy disk and running a bourne shell script called '''knoppix.sh''' from the root directory on this floppy. There is a GUI to create such a configuration floppy disk calles "saveconfig" (also located in the KDE menu under "KNOPPIX", but experts also know how to do this by creating their own shellscripts. The configuration with network and graphics setup are stored in '''configs.tbz'''. A file called ''knoppix.sh'', if located in the toplevel KNOPPIX directory on CD, will also be executed at startup. This makes it easier to create customized versions without having to change anything on the compressed filesystem KNOPPIX/KNOPPIX.
 
;myconf=/dev/sda1 :Run "knoppix.sh" from a partition - Knoppix V3.4
 
;myconf=scan (or config=scan) :Try to find "knoppix.sh" automatically - Knoppix V3.4
 
;noapic noagp noapm nodma nomce nofirewire nopcmcia noscsi noswap nousb nosmp noaudio : Skip parts of Hardware-detection, In case of a failing hardware autodetection, try booting with any of the "no-" options as shown in the table above, like in knoppix noagp noapm noapic nodma nopcmcia noscsi nousb to skip some critical parts of the autodetection system. The "noswap" option is useful for a forensic analysis without touching existing swap partitions.
 
;nofstab : By default Knoppix will look/scan the HDs to see if it contains partitions. If the HDs do have partitions, Knoppix will automatically build a '/etc/fstab' file and fill-in the appropriate partition entries and will also create the '/mnt/hdxx' mount points. The 'nofstab' cheat code prevents this look/scan and prevents the generation of the /etc/fstab and its mount points.
 
;nohwsetup : Skip hardware detection (does not run '''hwsetup''')
 
;pci=irqmask=0x0e98 : Notebook if PS/2 mouse doesn't work, Try "knoppix pci=irqmask=0x0e98" if (you have a notebook and) your PS/2 mouse doesn't work. (Possibly caused by a BIOS-flaw on your board.)
 
;ide2=0x180 nopcmia : boot from PCMCIA-CD (Transmeta notebooks)
 
;pci=biosirq : Will force the use of the BIOS assigned '''I'''nterrupt '''R'''e'''Q'''uests on the PCI bus. Possible cure for non-functioning hardware. Very handy for unruly IRQ conflicts. Look at '''dmesg''' and '''cat /proc/pci''' to find out if you have any such troubles..
 
;mem=128M : Specify Memory size in MByte, Some Boards apparently don't pass the proper memory size to the linux-kernel. It may cause the message "Panic cannot mount root file system" and the system hangs. Use "knoppix mem=128M" to solve that problem if your system has 128MByte memory for example (caution you MUST use a capital "M" here). Stuff like mem=16320K also works.
 
;noeject : Do NOT eject CD after halt
 
;noprompt : Its especially useful in combination with noeject. With noprompt, Knopix won't eject the CD and ask for a keypress. It was a much asked feature some time ago. Version 2003-09-22 and later.
 
;nodhcp : skip dhcp/network broadcast detection
 
;splash : It shows the upper half of the KDE splash-screen, while booting up. You can press Esc anytime to see all the messages. Ever wanted to hide those cryptic messages? Version 2003-09-22 and later.
* New in 3.4: Animations (see for yourself) and the ability to press ''any'' key.
 
;modules-disk : This cheatcode allows you to insert a floppy disk with additional modules, for example USB-stick or similar. Yes, its also possible with "expert", but there you loose the automatic configuration afterwards. Version 2003-09-22 and later.
 
;toram : Copy CD to RAM and run from there. Version 2003-09-05 and later.
 
;tohd : You can now do a "poor mans install" on vfat and ext2-Partitions with, '''knoppix tohd=/dev/hda1''' Version 2003-09-22 and later.
 
;fromhd : With this cheatcode the CD-Roms are ignored, so you can finally boot your "poor mans install" with just the original cdrom. Version 2003-09-05 and later. note - Cheatcode "toram" and "fromhd" work now together. Usage fromhd=/dev/hda1.
 
;boot=/dev/hda1
: (after you load kernel and run ramdisk startup stuff (minirt.gz) however you may choose)
:Then continue starting up from hda1/KNOPPIX/KNOPPIX . This is an easy way to free up your CD drive--you don't even need the CD at all, to boot, if you boot using loadlin, and have the 'linux' file and 'minirt.gz' file being loaded from the hard drive with loadlin. just copy the cd compressed contents to the root directory of a partition. then load knoppix with loadlin or however, passing this code in addition to the others, as you start up.
:This was tested to work on a fat32 partition, in knoppix 3.4. --[[User:gh78|gh78]] May 20 2006

;bootfrom=/dev/hda1 : Access Image then boot from previously copied CD-Image (enables booting from NTFS / ReiserFS) - Knoppix V3.4
 
;bootfrom=/dev/hda1/KNX.iso : Access image, boot from ISO-Image. - Knoppix V3.4

: NOTE: bootfrom needs access to a running Knoppix-System with the same Kernel as the Bootkernel, before it is able to mount the partition / ISO-Image. This should allow a poor mans install from NTFS-Partitions and makes it also possible to boot an ISO-Image directly. You can also use wildcards in the ISO-Filename, but it must be unique. So: If you have just one KNOPPIX.iso on /dev/hda1 you can access it as: bootfrom=/dev/hda1/K*.iso, but if there are several, you need to make clear, which one you want. (Feature added by Fabian Franz.)

: CAUTION: The 2.4 kernel that is in the KNOPPIX 3.4 CD does not support the ext3 filesystem so make sure that the ISO is stored in an ext2 filesystem.
 
;gmt|utc : Hardware clock is set to GMT/UTC
 
;tz=Europe/Berlin : Hardware clock is set to timezone Europe/Berlin
 
;vga=normal : No-framebuffer mode, but X
 
;vga=ext : 50-line TEXT mode
 
;dma : enable DMA for all IDE drives
 
;home=scan :Set home directory. 'scan' will search for knoppix.img in the root of all partitions. To create a home directory, go K-menu -> Knoppix -> Configure -> Create persistant home directory. Be carefull when creating the home-dir, Do NOT use the entire partition unless you know what you are doing. Other options could be, home=/dev/hda1/knoppix.img home=/mnt/hda1/knoppix.img . If you are using a USB memory stick type home=/dev/sda1/knoppix.img but home=scan will probably do.
 
;blind :Start Braille-Terminal (no X)
 
;brltty=type,port,table :Parameters for Braille device.
For more information on brltty parameters see http://mielke.cc/brltty/guidelines.html
 
;alsa :Autoconfigure alsa for an pci-soundcard
 
;alsa=es1938 :Configure alsa for the snd-es1938.o-module pci-soundcard
 
;testcd : Check CD data integrity, If your KNOPPIX CD makes strange noises during boot, or you see frequent errors like "cloop read error", or programs on your KDE desktop keep crashing randomly, then your CD image is probably defective or incomplete, or your CD-burner created a defective CD due to wrong writing speed or bad media. This is the most common error reported. Please boot with "knoppix testcd" to check if the CD is OK, and/or even better, verify the MD5 checksums that are present on the mirrors before writing the CD. Also, please read the KNOPPIX-FAQ.

: CAUTION: testcd can take a long time and the screen saver often starts while the testcd check is running. Hit SHIFT or CTRL to turn off the screen saver and continue, there is likely no need to reset the system or burn another CD at this point.
 
;pnpbios=off : No PnP Bios initialization
 
;acpi=off : Disable ACPI Bios completely
 
;pci=bios : Workaround for bad PCI controllers
 
;knoppix_dir=KNOPPIX : Directory to search for on the CD.
 
;knoppix_name=KNOPPIX : Cloop-File to search for on the CD.
 

;-b : "Emergency Mode", a quick-n-dirty boot, almost no HW detection, only 1 VT; hit enter at root-password prompt and start typing commands. Good if you just need to fdisk IDE devices, activate a different partition for booting, DD stuff, and you are planning on rebooting '''Real Fast''' after you're done. You can actually Alt-SysRQ-B safely ie. immediate reboot w/o worrying about shutting down nicely or anything, because nothing is mounted r/w at ALL - not even swap. Also works on other Linux distros.

==== Tips&Tricks ====
If you are unable to boot Knoppix (i.e. the screen goes blank, you see a kernel panic message, the screen flickers, you are dropped into a minimal shell, Knoppix simply freezes while booting, etc.), try these boot commands in order:
* '''boot: knoppix vga=0'''
* '''boot: knoppix acpi=off pnpbios=off noapic noapm''' Helpful for laptops
* '''boot: knoppix vga=0 debug -b 3''' Using this boot command will cause Knoppix to pause at various stages in the boot process. Just type 'exit' at each shell prompt to move on to the next stage. You will know that you are at the final stage when typing 'exit' does not do anything. If you get that far, type 'init 5' to go into graphics mode. 
* '''boot: failsafe debug -b 3''' That will do the same as the previous boot command, except turn off most of the hardware detection.
If you still have issues, please post in the [http://www.knoppix.net/forum/viewforum.php?f=9 Hardware & Booting] forum, tell us which of the above boot commands you tried, and how far in the boot process you were able to get.

Information for further troubleshooting:

Most of the boot options are parsed by different programs and scripts during the booting process, roughly in this order:

* the isolinux bootloader
* the linux kernel
* /linuxrc , which can be found in /cdrom/boot/isolinux/miniroot.gz -> linuxrc
* /etc/init.d/knoppix-autoconfig
* /etc/init.d/xsession
* /usr/sbin/mkxf86config
* /etc/init.d/knoppix-halt
* /etc/init.d/knoppix-reboot

For more information on passing boot parameters to the kernel, see 'man boot' and 'man bootparam'.

==saved files warning on shutdown==
Have it check the desktop and home directory for saved files when the user tries to shutdown. If files exist prompt to ask them if they want to continue with shutdown or continue the session so they can upload the files someplace.

== Mutiple Logins in Knoppix ==

I recently had an idea for non-server type computers. This would be
implementable on Knoppix, but could be applied to any distribution.

Right now, "knoppix home=scan" will scan media for a knoppix.img file.

<newidea>

It would be cool if the system looked for all files called
"home-*.img". For example, I might have a home-hal.img file which
would be an encrypted filesystem containg the user hal's home
directory.

Suppose it found two files: home-hal.img and home-dave.img. Then the
login screen would show four user options: default, hal, dave, and
new. Default would create a home directory in the ramdisk using the
default settings, just like Knoppix does now.

If I chose hal, it would ask for a passphrase. If that passphrase
works on the encrypted home directory, then it would add hal to
/etc/passwd, mount the encrypted filesystem at /home/hal, and log me
in.

The "new" option would create a new user and a new encrypted home
directory on whatever media is chosen.

</newidea>

The advantages are:

# One is not limited to the "knoppix" user.
# There can be mutliple home-directory images for multiple users on the same hard drive.
# This encourages use of encryption for security.
# It seems more natural security model. In the old model of enforcing security, the kernel is expected to respect /etc/passwd and home-directory permissions. User A could always use a live-cd to read User B's private files, even if User B had set the permissions on those files to keep them private.

This idea needs work. But I think it has some promise. --[[User:Hal|Hal]] 16:10, 30 May 2005

== Unique Hostname ==

It would be very nice and useful, if the hostname of the Knoppix box would be unique. This would allow, that there are several Knoppix hosts running on the same net. Currently, if dynamic dns and DHCP is used, only the first "knoppix" host gets added to the DNS.

One easy way would be, to add the MAC adress of the 1st NIC to hostname (without the : of course). This would make the hostname look something like "knoppix-0008743EFDE2".

Bugs/4.0.2CD

2006-04-13T08:17:30Z

Gh78:

1)The 4.0.2 CD at boot says: Welcome to the KNOPPIX live Linux-on-DVD!

THIS IS THE CD AND NOT THE DVD AS IT DISPLAYS!

2) Boot Option "knoppix no{swap}" is getting ignored (at least on an SATA Harddrive with Linux Swap partition). !!! Knoppix will still use the swap partition !!!

3) if toram boot option is used, shutdown does not work. After X-windows exit, shell prompt appears, but system does not do shutdown. Also poweroff or shutdown commands have no effect at all.

3a) if toram boot option is used, "knoppix-terminalserver" NFS does not work. The client side will say "Permission denied by server" when trying to mount the exported "/cdrom" dir. Have attempted modifying/blanking hosts.allow and hosts.deny, fiddling with export options, flushing iptables, and changing permissions/owners on the exported directory. This function works flawlessly when booted from CD.

4) not sure this is new, but while customizing 4.0.2CD I encountered a problem involving hotplugging multiple usb-storage devices. If one is mounted, and another is plugged in, the first device often seems to move to a new device but the old mount remains. There seems to be some explanation of this behavior in /sbin/hotplug-knoppix. Comments therein suggests the problem goes back to 2002. It would be the nice and expected behavior if plugging new storage doesn't booger up existing mounts. Any explanation of the issues involved would be helpful as well.

5) Starting knoppix with boot option "knoppix desktop=xfce" initiates successfully xsession, sound can be heard but when loading xfce desktop computer returns to shell screen with message X Window xsession terminated with errors.
Tried on x40, within vmware. all other options boot up correctly (in regard to xsession...)
no errors in xfreelogs:
(WW) VMWARE(0): Failed to set up write-combining range (0xfa000000,0x1000000)
(WW) VMWARE(0): Option "DPMS" is not used
(WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/truetype".
Entry deleted from font path.
(Run 'mkfontdir' on "/usr/share/fonts/truetype").
(WW) The directory "/usr/share/fonts/latex-ttf-fonts" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/X11R6/lib/X11/fonts/defoma/CID" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/X11R6/lib/X11/fonts/defoma/TrueType" does not exist.
Entry deleted from font path.
(WW) Open APM failed (/dev/apm_bios) (No such device)

just tried this on a quite typical desktop machine. same behaviour. desktop xfce seems to be broken.

6) /usr/share/knoppix/profile contains files and directories (e.g. .gnupg .mozilla .nessus.keys .netscape) which are copied into /home/knoppix when the X session is started (see rsync commands in /etc/X11/Xsession.d/45xsession). However, these files are '''owned by root''', not knoppix! So files which knoppix does not have permission to read '''fail to get copied''' (e.g. .nessus.keys). Only found this out because I was trying to add a .ssh directory in there and wondered why it failed to get copied across at boot time ... a swift ''chown -R knoppix.knoppix /usr/share/knoppix'' before re-mastering the Knoppix CD fixes this.

If you follow the instructions on the [[Knoppix_Remastering_Howto]], the equivalent command would be ''chown -R 1000.1000 /mnt/hda1/knx/source/KNOPPIX/usr/share/knoppix''.

7) Knoppix 4.02 CD won't boot on an IBM Thinkpad I Series 1161-43u. It only
displays "Disabling IRQ 15" over and over. Knoppix 3.8 CD works fine.
* Have you tried any of the cheatcodes? Have you cross posted this issue to the forum? --[[User:Rwcitek|Rwcitek]] 22:16, 5 Nov 2005 (GMT)

8) Change read/write mode not working with bootfrom-cheat ---
If I start knoppix with "knoppix bootfrom=/dev/hdb1/KNOPPIX.iso", and then right-click "Hard Disk [hdb1]" on Desktop and choose Actions->Change read/write mode, I get this error after confirming the action: "The remount command failed. Maybe there is another process accessing the filesystem currently."
I can still remount this manually with "sudo mount -o remount,rw /cdrom2.loop"
This bug is also present in 4.0.2-DVD
* Possible workaround: create a swapfile /mnt/hdb1/knoppix.swp. Have you cross posted this issue in a forum? --[[User:Rwcitek|Rwcitek]] 22:16, 5 Nov 2005 (GMT)

9) Knoppix-terminalserver
* clients/hosts booting with etherboot ROM's fail, because of some bug in the etherboot.nbi, but I'm not sure. can't find miniroot.gz, ... and than vmlinuz
* /etc/resolv.conf which is symlink to /etc/dhcpc/resolv.conf is not updated even for the hosts which boot with a PXE ROM, running netcardconfig with dhcp yes does the trick. --[[User:bsd|bsd]] Mon Nov 7 05:30:02 UTC 2005

10) CD 4.02 do not use the USB 2.0 full speed mode.
The error is in the linuxrc in /boot/isolinux/minirt.gz The line
USB2="ehci_hcd.ko"
should be
USB2="ehci_hcd"

11) There seems to be something wrong with the hardware detection of several versions of knoppix (all Knoppix versions with kernel 2.6.x that I tried, including the latest (4.0.2)):
I've written a forum entry describing the problem: http://www.knoppix.net/forum/viewtopic.php?t=22343
To be more specific, the wrong driver for a family of network cards is being loaded (or that's what I think), causing knoppix to crash on boot, while trying to get an IP from DHCP.

12) mkbootfloppy doesn't work, possibly since 3.7. I made a forum post, with a rather ugly fix, here: http://www.knoppix.net/forum/viewtopic.php?t=22949
It seems the problem is that if the second boot floppy is formatted as a 1722 KB disk then knoppix thinks the disk is corrupt at boot time. If the second boot floppy gets formatted as a 1440 KB disk then everyting is fine.

13) configure_bttv fails with xdialog usage message.
After review, i came to the conclusion that the error is caused by missing values in CARDLIST, when the radiolist construct runs for the tunners it should contain values of: "type=xx" but the only ones contained in the file is: "card=xxx".

14) Thomson TCM390 modem not detected ([[netusb]])

15) serial mouse not detected.
I had to edit the xfree86 config by hand.
--[[User:gh78|gh78]] Thu Apr 13 2006

16) isa modem not detected.
compaq netintelligent 56k isa modem works fine with knoppix v3.7, but not with v4.02
--[[User:gh78|gh78]] Thu Apr 13 2006

17) my airlink usb 2.0 usb-ethernet adapter is not detected during the startup.
I have to unplug it, then plug it back in for it to be recognized.
--[[User:gh78|gh78]] Thu Apr 13 2006

18) the console mouse driver, gpm, doesn't work with either mc, or elinks.
--[[User:gh78|gh78]] Thu Apr 13 2006

19) kppp has some bug that causes it to dial an unselected number--the dial action sometimes randomly selects between the various entrees. This is probably not the fault of the knoppix team, but I thought I'd mention it.

Hello.

I am a kinda beginner--a bit more advanced than a newbie.
I started with v3.3, then moved to v3.4 [thanks for the cd, kyle] then used v3.7, 3.81, 4.02.
I also try D.S.L. from time to time. [a v3.4 fork]
I'm interested in [http://freshmeat.net/projects/twin/ twin] and would love to see it on a cd.

I am saddened to see the lack of the 2.4 kernel--everything seemed to work much better back then.

I am quite happy to see the wiki working. open source *depends* on feedback from the users.

have a nice day

19) kppp has some bug that causes it to dial an unselected number--the dial action sometimes randomly selects between the various entrees. This is probably not the fault of the knoppix team, but I thought I'd mention it.

Hello.

I am a kinda beginner--a bit more advanced than a newbie.

I am quite happy to see the wiki working. open source *depends* on feedback from the users.

I hope you all take the time to give useful feedback as well--together we can make this corner of the world a better place.

Bugs/4.0.2CD

2006-04-13T07:28:43Z

Gh78:

1)The 4.0.2 CD at boot says: Welcome to the KNOPPIX live Linux-on-DVD!

THIS IS THE CD AND NOT THE DVD AS IT DISPLAYS!

2) Boot Option "knoppix no{swap}" is getting ignored (at least on an SATA Harddrive with Linux Swap partition). !!! Knoppix will still use the swap partition !!!

3) if toram boot option is used, shutdown does not work. After X-windows exit, shell prompt appears, but system does not do shutdown. Also poweroff or shutdown commands have no effect at all.

3a) if toram boot option is used, "knoppix-terminalserver" NFS does not work. The client side will say "Permission denied by server" when trying to mount the exported "/cdrom" dir. Have attempted modifying/blanking hosts.allow and hosts.deny, fiddling with export options, flushing iptables, and changing permissions/owners on the exported directory. This function works flawlessly when booted from CD.

4) not sure this is new, but while customizing 4.0.2CD I encountered a problem involving hotplugging multiple usb-storage devices. If one is mounted, and another is plugged in, the first device often seems to move to a new device but the old mount remains. There seems to be some explanation of this behavior in /sbin/hotplug-knoppix. Comments therein suggests the problem goes back to 2002. It would be the nice and expected behavior if plugging new storage doesn't booger up existing mounts. Any explanation of the issues involved would be helpful as well.

5) Starting knoppix with boot option "knoppix desktop=xfce" initiates successfully xsession, sound can be heard but when loading xfce desktop computer returns to shell screen with message X Window xsession terminated with errors.
Tried on x40, within vmware. all other options boot up correctly (in regard to xsession...)
no errors in xfreelogs:
(WW) VMWARE(0): Failed to set up write-combining range (0xfa000000,0x1000000)
(WW) VMWARE(0): Option "DPMS" is not used
(WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/truetype".
Entry deleted from font path.
(Run 'mkfontdir' on "/usr/share/fonts/truetype").
(WW) The directory "/usr/share/fonts/latex-ttf-fonts" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/X11R6/lib/X11/fonts/defoma/CID" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/X11R6/lib/X11/fonts/defoma/TrueType" does not exist.
Entry deleted from font path.
(WW) Open APM failed (/dev/apm_bios) (No such device)

just tried this on a quite typical desktop machine. same behaviour. desktop xfce seems to be broken.

6) /usr/share/knoppix/profile contains files and directories (e.g. .gnupg .mozilla .nessus.keys .netscape) which are copied into /home/knoppix when the X session is started (see rsync commands in /etc/X11/Xsession.d/45xsession). However, these files are '''owned by root''', not knoppix! So files which knoppix does not have permission to read '''fail to get copied''' (e.g. .nessus.keys). Only found this out because I was trying to add a .ssh directory in there and wondered why it failed to get copied across at boot time ... a swift ''chown -R knoppix.knoppix /usr/share/knoppix'' before re-mastering the Knoppix CD fixes this.

If you follow the instructions on the [[Knoppix_Remastering_Howto]], the equivalent command would be ''chown -R 1000.1000 /mnt/hda1/knx/source/KNOPPIX/usr/share/knoppix''.

7) Knoppix 4.02 CD won't boot on an IBM Thinkpad I Series 1161-43u. It only
displays "Disabling IRQ 15" over and over. Knoppix 3.8 CD works fine.
* Have you tried any of the cheatcodes? Have you cross posted this issue to the forum? --[[User:Rwcitek|Rwcitek]] 22:16, 5 Nov 2005 (GMT)

8) Change read/write mode not working with bootfrom-cheat ---
If I start knoppix with "knoppix bootfrom=/dev/hdb1/KNOPPIX.iso", and then right-click "Hard Disk [hdb1]" on Desktop and choose Actions->Change read/write mode, I get this error after confirming the action: "The remount command failed. Maybe there is another process accessing the filesystem currently."
I can still remount this manually with "sudo mount -o remount,rw /cdrom2.loop"
This bug is also present in 4.0.2-DVD
* Possible workaround: create a swapfile /mnt/hdb1/knoppix.swp. Have you cross posted this issue in a forum? --[[User:Rwcitek|Rwcitek]] 22:16, 5 Nov 2005 (GMT)

9) Knoppix-terminalserver
* clients/hosts booting with etherboot ROM's fail, because of some bug in the etherboot.nbi, but I'm not sure. can't find miniroot.gz, ... and than vmlinuz
* /etc/resolv.conf which is symlink to /etc/dhcpc/resolv.conf is not updated even for the hosts which boot with a PXE ROM, running netcardconfig with dhcp yes does the trick. --[[User:bsd|bsd]] Mon Nov 7 05:30:02 UTC 2005

10) CD 4.02 do not use the USB 2.0 full speed mode.
The error is in the linuxrc in /boot/isolinux/minirt.gz The line
USB2="ehci_hcd.ko"
should be
USB2="ehci_hcd"

11) There seems to be something wrong with the hardware detection of several versions of knoppix (all Knoppix versions with kernel 2.6.x that I tried, including the latest (4.0.2)):
I've written a forum entry describing the problem: http://www.knoppix.net/forum/viewtopic.php?t=22343
To be more specific, the wrong driver for a family of network cards is being loaded (or that's what I think), causing knoppix to crash on boot, while trying to get an IP from DHCP.

12) mkbootfloppy doesn't work, possibly since 3.7. I made a forum post, with a rather ugly fix, here: http://www.knoppix.net/forum/viewtopic.php?t=22949
It seems the problem is that if the second boot floppy is formatted as a 1722 KB disk then knoppix thinks the disk is corrupt at boot time. If the second boot floppy gets formatted as a 1440 KB disk then everyting is fine.

13) configure_bttv fails with xdialog usage message.
After review, i came to the conclusion that the error is caused by missing values in CARDLIST, when the radiolist construct runs for the tunners it should contain values of: "type=xx" but the only ones contained in the file is: "card=xxx".

14) Thomson TCM390 modem not detected ([[netusb]])

15) serial mouse not detected.
I had to edit the xfree86 config by hand.
-gh78

16) isa modem not detected.
compaq netintelligent 56k isa modem works fine with knoppix v3.7, but not with v4.02
-gh78

17) my airlink usb 2.0 usb-ethernet adapter is not detected during the startup.
I have to unplug it, then plug it back in for it to be recognized.

18) the console mouse driver, gpm, doesn't work with either mc, or elinks.
-gh78

19) kppp has some bug that causes it to dial an unselected number--the dial action sometimes randomly selects between the various entrees.
This is probably not the fault of the knoppix teram, but I thought I'd mention it.
