I'm seeing this regularly as well. Often I am doing something with video or audio. This last time, I launched an mp3 in VLC, and the screen immediately froze. The audio kept playing. About 15 minutes later, when the mp3 ended, the screen immediately unfroze and everything seemed fine.

Often, I can't wait to see if it will come back, and sometimes it never does, so I have to reboot. This is brutal for things like presentations, having no idea if the machine will suddenly just freeze. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1660619 Title: kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1660619/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
