> Is your KDM configured to restart X on logout? No, I don't think so. I didn't touch the TerminateServer directive in /etc/kde3/kdm/kdmrc:
# Restart instead of resetting the local X-server after session exit. # Use it if the server leaks memory etc. # Default is false #TerminateServer=true > Does anything appear in the log when the problem occurs? No, I don't see anything out of the ordinary. > Can you unplug/replug the keyboard? No, it's a laptop. But I also have a wireless USB keyboard and mouse connected. That keyboard didn't work either when the lock-up occurred. Next time I will try to unplug and reconnect the external keyboard. Actually the wireless mouse acts strangely as well, it stops working every now and then (but the built-in touchpad still works). Replugging does not help here. I don't know if it is related to this issue.
