This is happening frequently in my computer. It usually happens after a long uptime, after some suspends/wake ups cycles, when I try to maximize or half-maximize windows in unity by dragging them.
It requires a hard reboot to get the system working again (trying to start unity or to restart the lightdm service doesn't work). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1147370 Title: [arrandale mesa] GPU lockup IPEHR: 0x7a001002 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1147370/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
