I have a question...
If I try to work to fast on Knoppix sometimes an application will freeze up. Then I have to restart my computer and start knoppix again to get rid of it. Is there an easier way to just like completely clear all applications running?
You can use xkill to kill an application, or type in a konsole "ps fax" without the quotes to get the PID for the stopped app and do "kill pidnumber" or "killall application-name". If kill doesn't work try "kill -HUP pidnumber".
why kill them all?
Go to a vt (lets say: ttyS2, to do that, hitt ctrl+alt+F2, to get back to KDE and X hit, ctrl+alt+f5, could be F1, F3, F4... be patient it might take a few seconds for the screen to wake) and type ps -A look for the name of what is bothering you.
if i had a frozen centericq i would do
output would be a looooong list (i have some 6 xterms), here is a part of that output.Quote:
ps -A
then aCode:
652 ? 00:00:00 fvwm95
686 ? 00:00:40 gkrellm
687 ? 00:00:00 FvwmTaskBar
688 ? 00:00:00 FvwmButtons
692 ? 00:00:00 xterm
702 pts/0 00:00:01 centericq
would do just that, kill the process with number 702. it might be that it won't die, hmmm, ok.Code:kill 702
that would work. if not, hmmm. ok lets pretend it did not work, check if something keeps it alive (is above it in the ps tree)Code:kill -9 702
ps -aux then kill anythng assosiated with centericq, and ofcource centericq).
in this case Xterm.

if it survives this it is a Zombie process (yes it is the actuall name) and canot be killed short of reboot.Code:kill -9 692 702
