Comment 10 for bug 1059467

I just add ppa:ubuntu-x-swat/q-lts-backport and update packages and reboot. I still got the exact same behavior. xserver-xorg-video-intel wasn't updated.

What is the way to go back to Unity 5.14 to be sure that the trouble came with 5.16 ? I had some video troubles that were similar mouths ago when precise wasn't release.
