I get this problem with only 1 user. The computer crashes at random - no matter if I'm at the computer or not. My graphics card is an ATI 9800XT (with the proprietary drivers enabled).
The error started to appear after I installed a new SATA2-drive (samsung, 500Gb) to my machine. Before this there were no problem. Until yesterday I hadn't found any clues in the logs but yesterday my computer crashed twice and on both occasions the following log entries were found in daemon.log Jun 19 18:24:42 Lysander gdm[5744]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting: 0 Jun 19 23:42:45 Lysander gdm[5774]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting: 0 Attached is the Xorg.0.log from the time of the later crash. ** Attachment added: "Xorg.0.log.old" http://launchpadlibrarian.net/15469639/Xorg.0.log.old -- gdm_slave_xioerror_handler: Fatal X error https://bugs.launchpad.net/bugs/152648 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
