1.) The Knoppix V4.0 DVD did not boot and hung. In debug mode i found that there were ACPI warnings "executable code found at module level". The solution to this was to remove the USB card reader I had plugged in. After that the boot sequence finished ok. I do not know if this error is worth being tracked. I cannot really make a connection between ACPI and a USB device. If anyone is interested in the issue I will send additional data.

- I had a similar problem. Used the "nousb" option - booted fine.

- I think that this may be a local/BIOS problem specific to a board. Have you tried "knoppix acpi=off noapic pnpbios=off pci=bios" to change the way the BIOS allocates interrupts between devices? -KK

2.) Knoppix needs a povray raytracing engine if it is to have KPovModeller. Here is the error:

i) Load up Graphics--> KPovModeller. ii) (It comes up with a basic scene). iii) Hit View--> Render iv) It gives the error message: "Couldn't call povray. Please check your installation or set another povray command."

A discussion of possible workarounds (including my wishlist) can be found at: http://www.knoppix.net/forum/viewtopic.php?p=88147#88147 . I would note that I entered it into a feature request at that forum and was directed to report this as a bug. Paipix 3.6 FWIW does not give this error because it has a povray engine. (submitted by PterandoN, pterandon)

- Problem: povray is NOT FREE SOFTWARE. The license is incompatible with a free distribution for any purpose, including commercial ones. So, I'd rather remove kmovmodeler in 4.0.1. Sorry. -KK


I'm afraid you're mistaken. Povray is FREEWARE. I've had a member of POV-Team assert that its license is fine for distribution like Knoppix. It is already distributed on:

i) klik (http://klik.atekon.de/index.php?section=graphics/ ) ii) mediainlinux (http://www.mediainlinux.org/index.php/mediainlinux/news/release_news/mediainlinux_3_beta_version_release_notes) and iii) Paipix (If you invoke the "Render" on kpovmodeller, it invokes povray application. iv) eduknoppix (http://eduknoppix.dmf.unicatt.it/) as far as I can see.

Sorry, "Freeware" does not make it "free software". Read http://www.povray.org/povlegal.html thoroughly. You may NOT distribute povray commercially without restrictions, therefore a computer magazine, for example, could NOT include a Knoppix CD anymore if povray is in it, unless the magazine gets a written permission from the povray legal owners. Also, each and every redistributor pf a Knoppix with povray needs to also accept the quite complex povray REDISTRIBUTION license at http://www.povray.org/distribution-license.html. Sorry, at this point, I really think it gets inacceptable. If the povray authors would agree to distribute povray under an OSI-approved license (http://www.opensource.org/) instead of the current one, I see no problem for the inclusion in Knoppix. -KK


Hello, please see pertinent points of povray license, as see at:


Respectfully yours, PterandoN



Knoppix 4.0 booted from DVD:

- No sound. When I go to "Kontrollsystem - Soundsystem aktivieren" I get the message: Error while initializing the sound driver, device /dev/dsp can't be opened (No such device). The sound driver doesn't seem to be installed. It's a Soundblaster AWE 64 Gold, with Knoppix 3.4 it works.

- Could you let me know which soundcard (PCI vendor and version ID) and which module has worked for your card in 3.4? Also, I would recommend booting with the options mentioned under 1.) -KK

- Can't edit Grub bootloader with the system tool "Systemstart". The Bootloader can't be found.

Knoppix 4.0 installed on hard drive:

- No sound. Same problem as above.

- Now the Grub bootloader is found, but the entry of Windows XP starting isn't displayed. Changes doesn't affect anything, either.

- Open Office 2.0 doesn't start (Knoppix' size is only 6 GB on my hard drive, I thought it should be around 10 GB. Perhaps some files are missing.).

- Looks like /KNOPPIX was copied to harddisk, which doesn't contain /opt/openoffice. The installer should have used /UNIONFS as source instead. Easy fix: Boot the DVD, mount your install partition at /mnt/hd, and then do a "cp -a /KNOPPIX2/* /mnt/hd/" as root. -KK

- No USB hard drives are getting detected.

- Works for me.

Perhaps you can fix some of these problems by hand, but it will be nice, if it works out of the box. I know, that Knoppix isn't made for installing on hard drive, but many people do so and perhaps it is not so much work to fix the problems.

4.) desktop=openbox at boot doesn't work (standard KDE comes up). The openbox option in the restart X program does work.

- Problem with knoppix-autoconfig, which did not have openbox in the list of "syntactically correct" desktop variants. Line removed in 4.0.1. -KK

5.) Compaq Presario V2335 laptop. No sound after hard drive install. Used to work fine with Knoppix 3.9. Should be compatible with snd_i8×0 driver but no sound at all. Here's the lspci -v output for the soundcard. Already tried booting with tried "knoppix acpi=off noapic pnpbios=off pci=bios" but still has the same problem. Thanks!

6.) There is a bug in linuxrc script created with /etc/init.d/knoppix-terminalserver. There is a code

echo "Loading network device module(s)"
for i in $(cd /modules/net; echo *.*o); do
case "$NFSMODULES" in
*$i*) ;;
*) $INSMOD /modules/net/$i >/dev/null 2>&1 && \
case "$i" in 00*) ;; *) echo "${CRE} ${GREEN}Found network device(s) handled by   ${MAGENTA}$i${GREEN}.${NORMAL}" && FOUND_NETWORK="$i" ;; esac

# Enable kernel messages again
echo "6" > /proc/sys/kernel/printk
/static/ifconfig lo up

[ -n "FOUND_NETWORK" ] || dropshell

on the last line should be variable name $FOUND_NETWORK instead of plain string "FOUND_NETWORK"

[ -n "$FOUND_NETWORK" ] || dropshell

Am I right? Maybe it's already updated in version 4.0.1.
