Hello, I had the same problem with my hardware (Asus Ux303LA, Intel 5500, i7)
It appears to have been fixed upstream in drm-intel-next, You can try it using a kernel with the latest drm-intel-next, which you can get from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm- intel-next/current/ I also use i915.enable_execlists=0 as a kernel parameter and it appears to be stable now. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1432194 Title: Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1432194/+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
