Q: Why does "df" not list my root partition ("/")?

A: The entry for "/" is somehow missing in /etc/mtab. Either edit that file and add a correct line for "/" or better replace /etc/mtab with a link to /proc/mounts, thn everything should be shown.

  • su -c "ln -sf /proc/mounts /etc/mtab"

Q: Why is DMA disabled by default and how do I enable it?

A: Some chipsets and/or harddiscs are broken or buggy. Using DMA would cause problems on such systems. If your system works properly with DMA, you can enable it with it by typing "/sbin/hdparm -c3 -d1 -m16 -k1 /dev/hda" or by editing the "/etc/init.d/" 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".

Q: How do I test the downloaded ISO file?

A: You can use md5sum -c filename.md5 in Linux or md5gui for windows.

Q: How do I install Knoppix over a Network?

A: Install Over Net HowTo

Q: Is there a way that does not use so much space?

A: There is the "Poor Mans Install", where you can copy some files from the CD to the harddisk. It will run like from CD, but the CDROM is free for other use and its a bit faster. Although you'll need a bootfloppy or change the Bios options to boot first the hard disk with Knoppix (i.e. the second hard disk or d: unit).

Q: Is there other way that does not use so much space? Perhaps by having a compressed file system?

A: Yes, you can install Knoppix in 700 megs instead of 2.3 gigs for the real install, but it will run as if it were from a physical CD, so you cannot install anything, unless you do a 'normal' install. Each time you boot your hardware will need to be redetected. This is not for novices. For more information see the HOWTO for the Hd Based HowTo hard drive based install.

Q: Why doesn't my sound work?

A: Just run "/etc/init.d/alsa-autoconfig" as root once and you'll be fixed up nicely. To have the sound levels set at boot (alsa defaults to muted) edit the file "/etc/init.d/" and add aumix -w 75 -v 75 to the bottom of the file.

Q: How do I install the latest Gnome?

A: Comment all the lines in /etc/apt/sources.list except the unstable ones.

  • apt-get update
  • apt-get install gnome

In order to have gnome-session working you must execute the following and choose metacity

  • update-alternatives --config x-window-manager

Optionally you can also install gdm, galeon, evolution, etc.

Q: how to install knoppix-terminalserver and/or knoppix-terminalopenmosixserver ???
