Thank you for the bug report. This could possibly be a manifestation of this upstream bug:
https://bugs.freedesktop.org/show_bug.cgi?id=27108 I'm not going to link to the upstream bug until we're sure. In the meantime, I'll try to get a test kernel built with the two patches known to fix the problem, and see if they solve it for you. Your test case is valuable, as the upstream bug is random and not easily reproduceable. ** Bug watch added: freedesktop.org Bugzilla #27108 http://bugs.freedesktop.org/show_bug.cgi?id=27108 ** Changed in: linux (Ubuntu) Status: New => Confirmed ** Changed in: linux (Ubuntu) Importance: Undecided => Medium -- Blanking screensaver doesn't activate until mouse is moved https://bugs.launchpad.net/bugs/577070 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
