Output Log

I'm getting a crash on startup (of the X server) when I both load the intel driver and the synaptics module. If I don't load the synaptics module, it runs fine.
The crash happens in v2.3.1 and v2.3.2, but not in 2.2.1.

The Xorg.log reports:

Xserver crashed when applying quirks to your monitor...interesting, could you take action like in http://www.x.org/wiki/Development/Documentation/ServerDebugging with more info on segfault backtrace?

Turn on "ModeDebug" option in Device section may also help with some debug info in X log.
Comment 3 Sander Jansen 2008-06-24 20:38:34 UTC
Hmmm weird... turning on "ModeDebug" makes it not crash anymore...
Comment 4 Michael Fu 2008-07-10 02:05:45 UTC
Jansen, Are you able to follow the debug link in zhenyu's last comment to collect more info? Can you still report this issue if not using ModeDebug option? what's the version of synaptics module?
Comment 5 Wang Zhenyu 2008-07-28 00:11:11 UTC
Clearly not intel driver issue, if still has problem, reopen new track for right component. Thanks.
