I hope this isn't old news, but I've done a little bit of testing and found that the following lines appeared in my /var/log/Xorg.0.log when this freeze occured: [ 4255.536] (WW) intel(0): flip queue failed: Invalid argument [ 4255.536] (WW) intel(0): Page flip failed: Invalid argument
I understand that the numbers in square brackets are timestamps of number of seconds since boot. I haven't found a simple way of converting these to human readable times (knowledge of the 'date' command clearly lacking) but at any rate, a google of these lines lead me to comments 30 and 38 on bug 966744 which seems to suggest that these two bugs are at least related if not actual duplicates. Can anyone confirm that these line are appearing in their Xorg.0.log (if viewing in during a freeze using tty) or Xorg.0.log.old after running 'sudo service lightdm restart' and getting back to X (by running: grep "Invalid argument" /var/log/Xorg.0.log)? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995013 Title: Xorg freeze after lid closed/opened (screen turned off/on) several times To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/995013/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
