What to do if the computer window seems locked up

If the computer display window seems to be locked up, all is not lost. The operating system is likely running just fine; you have instead experienced a glitch with the X windows server or the KDE desktop server. Here are some ways to try to fix this problem:

1. Try alt-control-backspace to reset the X windows server. (On Linux, this resets the window server rather than rebooting the computer).

2. Log in from another computer using ssh. Do su root if you know the password (or get help from someone), and do kdm restart. If that doesn't work, do

     ps -A | grep kdm
   

   and kill the process listed (such as 12344) with

     kill -9 12344
   

If somehow this fails, see Sec. 6.10 for instructions on how to reboot the computer.
