Process kdesktop is running but there is additionally a "[kdesktop_lock] <defunct>" process. Might this be the culprit? I do not lock my desktop normally. I can not kill the <defunct> process but killing kdesktop process and relaunching it restores all to normal.
now I have a running 21927 pts/4 S 0:00 kdesktop 21928 pts/4 S 0:00 /opt/trinity/bin/kdesktop_lock --internal 21927

Sounds almost like kdesktop is deadlocked. Next time it happens can you break into kdesktop with gdb (gdb --pid `pidof kdesktop`), execute "thread apply all bt", and post the output?
Thanks!

Today it happened again - and yes, I installed tdebase-trinity-dbg.
Output is not much. Here you are: (gdb) thread apply all bt

Don't know if this helps for anything. I try again next time. Gerhard
