Can you describe a procedure how to reproduce this problem?
Well... I cannot accurately reproduce this problem. I just executed startx. That's all. I don't know whether it can reproduce the problem, not. However, I guess that it has happened only when it execute startx first after system bootup. BTW I found a core file related to this problem.

I just executed startx. That's all.
I almost never use startx, nevertheless I had these segfaults sometimes on my x86_64 machines. Therefore, I think it has nothing to do with startx. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
