As suggested here: http://ubuntuforums.org/showthread.php?t=2249774, a workaround is to upgrade to gnome staging. The forum post suggests testing, but staging solved all problems for me:
sudo apt-add-repository ppa:gnome3-team/gnome3 sudo apt-add-repository ppa:gnome3-team/gnome3-staging sudo apt-get update sudo apt-get dist-upgrade This can of course introduce other problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386721 Title: Graphics Slow After Upgrade 14.04 - 14.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1386721/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
