Hi openSUSE community,
I have a strange problem with X under openSUSE 11.2. After starting KDE 4.x
or Gnome, the Xorg system freezes after 5-15 minutes. If that occurs I can
still move the mouse, but any click or keyboard event is not recognized any
more. Can't switch to console. But the system itself works, since I can
login by ssh. All running (server) applications like Apache and MySQL still
work. In order to use X again, I have to reboot (init 6 does not work, I
have to type "reboot " twice). init 3 and init 5 does not work after logging
in by ssh, killing X process does also not fix it. I really have to reboot.
I have an Intel 855GM Integrated Graphics Device on board. I have already
checked the RAM with memtest, everything okay. There are no error messages
in syslog. I have tried disabling DRI, but no effect. Disabling Video cache
in BIOS or reducing the video buffer size did also not help.
Without logging in to KDE or Gnome the system runs stable for weeks, so I am
pretty sure that Xorg is the problem. I guess that these problems are caused
by the Intel graphics driver. I can remember that I had similar problems 1-2
years ago (freezes only with KDE 3 and 4, not Gnome). I am pretty sure, that
the first problems started after switching to the Intel driver (from the old
810 driver), but in openSUSE 11.1 it was running fine. Now in openSUSE 11.2
the X system freezes after some minutes working.

Any ideas ?
