Comment 21 for bug 440233

Thanks for the confirmation Ocram.

I think it might help if you can attach your /var/log/Xorg.0.log file (note that the 0 increases on every boot, so if you, for example, have rebooted once since the error, the correct log will be Xorg.1.log. See if you still have the log from the failed boot laying around. Look for errors near the bottom.).
