Confirmed on an Intel video card. This is a MAJOR problem, because suspend/hibernate changes VT's, and a change in VT triggers this bug.
Easy way to trigger this bug: after logging into GNOME via GDM, press CTRL+ALT+2 to go to VT #2, then go back to the VT where you were logged into GNOME. It will have crashed, leaving you with a GDM login screen. lspci of video card: 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) Pruned /var/log/syslog output: May 11 16:28:00 extensia kernel: [ 560.294382] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0 May 11 16:28:00 extensia x-session-manager[4430]: WARNING: Detected that screensaver has left the bus May 11 16:28:00 extensia gdm[4127]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting :0 May 11 16:28:00 extensia bonobo-activation-server (kuba-4984): could not associate with desktop session: Failed to connect to socket /tmp/dbus-hTpBtBgWnJ: Connection refused -- [jaunty][alpha6]X-Server restart randomly https://bugs.launchpad.net/bugs/342324 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
