This happened to me three times today, running Gutsy (installed RC and all updates since then). I am running GNOME and Compiz-Fusion on an Intel GMA-950 with the intel driver.
I only had Firefox running in one session of the three, so this might be unrelated. However, all three times it happened was when I was switching workspaces with Ctrl+Alt+arrows (Compiz Desk Wall plug-in). I have added the line "VideoRam 131072" to my xorg.conf Device section yesterday in hope of increased performance (like I did in Feisty). I haven't come accross this problem since the day Gutsy RC was released, so I removed that line and I will see if that was somehow related. -- X crashes gdm_slave_xioerror_handler: Fatal X error - Restarting :0 https://bugs.launchpad.net/bugs/140554 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
