System hangs because of X Server crash


About once a day, my system seems to hang (mouse can’t be moved, no keyboard input possible, screen stays unchanged)

After a restart I can find an error in /var/log/kdm.log:

What can I do, to debug this problem? Or is there an easy solution?


I don’t have a definitive answer for you, but it might be useful to post the output of /var/log/Xorg.0.log

It can be a large file, so cut and paste to

SUSE Paste

then post the link to it here.

By chance, you didn’t try installing the proprietary ATI driver? (As the 200M is not supported by that any longer)

I am getting a similar crash. The desktop freezes, the mouse still moves.

Output from /var/log/Xorg.0.log.old:

I am going to try the nvidia driver instead, see how I get on.


and I thought, I’m the only one suffering this error. I’m interested, if changing the driver will help you. But as I’m using radeon driver instead of nouveau, I think the problem is located somewhere else. When it crashes again and if I’m able to save, I will post the file. Is it possible to get more debug information by installing …-debug package?


it crashed again and I could save a few files:

xorg.0.log.old: SUSE Paste

kdm.log: SUSE Paste

messages (today): SUSE Paste

Would be nice, if someone could have a look at these files.

Thank you

This doesn’t look good:

along with the associated backtrace. I think you will need to take the advice in the logs and consult X.Org Wiki - Home and X.Org Foundation. The logs will be useful to them as a starter. Check for existing bug reports as well.
