I am not certain it makes a difference (I haven't tested it yet) but I believe Chromium did not lock up until after I installed the HWE kernels in 14.04. It's also possible this started after some update to Chromium, though I am almost certain it didn't lock up my system as long ago as the bug reporter reported it. (I have seen it locked up in the past on different systems, however, and in that case it seemed to be a crash involving the video driver.)
I have found a procedure that ALWAYS locks up my system now -- if I have "use hardware acceleration" checked (turned on) and open a video in YouTube, make it full screen, then undo the full screen, the screen locks up (even while the video continues playing for a few seconds). I have found I can switch to a virtual terminal (Ctrl-Alt-F1 for example) and see processes still running, but I have not yet found any process I can kill off or restart to unlock the screen EXCEPT to get Unity to restart. All I have to do to restart unity is issue a unity -v command and all the running applications will die and unity will restart, allowing me to log in. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1499756 Title: Ubuntu 14.04 LTS freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1499756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
