Any more details available like the output of 'dmesg' and /var/log/Xorg.0.log at the time where the freeze happens?

Hmm. The famous  

  "[mi] EQ overflowing. The server is probably stuck in an infinite loop."

sympton with a lot of possible culprits, most likely related to a graphics
driver problem. :-(

Comment 5 Andrej Vilfan 2011-12-23 14:28:49 UTC

Same thing happening to me. While I can't definitely exclude that it sometimes happens in other situations, the crash is much more likely if BOTH conditions are fulfilled:

- An external display was connected to the computer at some point since booting.
- The computer has been suspended to RAM

I can pretty much avoid problems by either not using an external monitor or, whenever I do, not using the sleep mode.

Comment 6 Stefan Dirsch 2013-03-05 10:25:51 UTC

openSUSE 11.4 is no longer supported. Feel free to reopen, if the issue still exists with openSUSE 12.3. Thanks.
