Public bug reported: SRU Justification:
Impact: When multiple DRI applications are running on an i965, and the screen goes into standby, one of the applications will sometimes hang when the screen is woken back up. Sometimes this occurs with compiz, which renders the desktop unusable. In at least one case, the hang was in DRI2GetBuffersWithFormat, though I don't know that that's consistent. Fix: Bisected e8e7a2b8ccfdae0d4cb6bd25824bbedcd42da316 as fix from upstream kernel Testcase: While using Unity, run "glxgears &" and "xset s 1". Continue to wake up the screen when it goes into standby. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Natty) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/848687 Title: DRI applications hang after DPMS standby on i965 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/848687/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
