Keyboard or program doesn't respond

Keyboard doesn't respond

Check first, if you can change to a text konsole using [Strg] + [Alt] + [F2] (With [Strg] + [Alt] + [F1]
you will get back to the graphical console). If the answer is yes, then most likely one of your programs hung up
(see next paragraph). If not, unplug the keyboard cable and plug again to the workstation PC. If this doesn't help,
ask an admin (room 010 and 011).

A program isn't responding

You may use the command top to check main memory usage and cpu-time consumption of the running programs
(quit top by typing [q].) Using ps x or ps ux will show your own currently running processes.

Both displays will give you the PID (process ID) of the programs/processes. Yor own processes will be aborted with
the command kill [Process-ID].

If nothing else helps you can restart the system with the key combination [Strg] + [Alt] + [Backspace]. This
will bring you back to the login display. Please note: all data not safed will be lost.

If that doesn't work there is a larger problem. In that case, please inform our admins at room 011 or room 010.
