I have tried the daily-current, and I could not reproduce the bug by running it for 20 hours, and usually I can trigger the bug within an hour.
But, I could get the livecd to match my current setup exactly. For one thing it uses unity and not gnome-shell, and I can't install things temporarily with apt-get. So I had to use a statically compiled chromium instead of google chrome. I have found two ways of triggering the bug, and it is still there on "Ubuntu 14.04.5 LTS", and that is by letting one of these two links run for a long time in google chrome. http://xkcd.com/1663/ or https://vicandblood.itch.io/dopesmoker And it only happens with Chrome and not Firefox. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567841 Title: One of my two graphics cards has started to freeze the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1567841/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
