I tried the upstream kernel and could not reproduce the issue by making the monitor sleep 10 times in a row. The standard Ubuntu kernel has been broken all the time (though the issue only manifests every now and then).
So either that patch alone is not sufficient or I just had poor luck in trying to reproduce the bug with an upstream kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1186959 Title: Regression: Intel graphics fails when bringing monitor out of sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1186959/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
