Thanks for this bug report. Since this really sounds like a hardware failure rather than a genuine bug, can you provide these informations?
1. Are you able to start glxgears and let it turn for a hour or your computer automatically reboot? 2. Can you describe exactly what do you mean by "restart"? Does your computer switch right to the BIOS screen and boot again? Or you see ubuntu rebooting like if you were rebooting it manually? 3. Can you give us the result of that command typed in a terminal : lspci -nn | grep VGA 4. Can you give us the result of that command typed in a terminal : cat /etc/X11/xorg.conf | grep -A 4 'Section "Device"' Thanks for your contribution to ubuntu. ** Changed in: compiz (Ubuntu) Assignee: (unassigned) => Saïvann Carignan (saivann) Status: New => Incomplete -- laptop randomly restart while compiz is enabled https://bugs.launchpad.net/bugs/152216 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
