Feel free to bisect xserver-xorg-video-intel between 2.99.914..2.99.917 if it's fixed in 15.04 (which has .917). Only when something has been identified to fix something it'll be SRU'd.
I can't reproduce any of the issues with current utopic-proposed (or the equivalent lts backports), and I have the same GPU on my laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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/linux/+bug/1432194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
