Public bug reported: Binary package hint: xserver-xorg-core
Since upgrading from 10.10 to 11.04, X crashes occasionally, maybe 1-3 times per day. I have tried a variety of troubleshooting measures to isolate the problem, but without success: 1. The crash occurs with the fglrx, ati/radeon, and fbdev drivers, so it doesn't seem to be specific to a particular driver 2. The crash still occurs after downgrading to a 10.10 kernel, so it doesn't seem to be specific to the new kernel 3. The crash occurs with the standard Xorg packages from 11.04, the packages from ubuntu-x-swat, and the packages from xorg-edgers. The crash only happens when I'm actively using the system - I never come back to it to find it at the login screen.
