SNA is not the default for quantal. No, there is not a way to toggle between UXA and SNA at run time. /var/log/Xorg.0.log is where to look to see which acceleration tech is active.
If I understand your testing feedback, you do believe SNA helps eliminate the freeze behaviors, and thus we can consider UXA the likely source of the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1041790 Title: [sandybridge-m-gt2] GPU lockup IPEHR: 0x0b160001 IPEHR: 0x0b140001 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1041790/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
