Thank you for the reply Anders,
I upgraded the 10.1 box to 10.2 and problem disappeared.
On the other box, upgrade is not as easy (I did not put /home on a separate
partition, silly me). However, your hint about VNC was probably good. I
looked at the firewall ports open, and found that I (Yast ?) opened both 5800
and 5900 port which are required for VNC over http I believe. I do not use
this feature. I need a VNC connection but I use krdc for it (and it is
protected by a password). After blocking these 2 ports as well as 2 other
ones (631 and X) (I don't remember the second one and I dont remember why i
opened them !) the X server do not crash anymore.
So up to now, problem is solved.
Thanks again
Cheers
