My laptop was not booting anymore. I was adviced to reinstall the older xserver-xorg-core (1.17.1-0ubuntu3) and that fixed it.
The overlay ppa currently offers:
xserver-xorg-core ---> 1.17.2-1ubuntu0.1~overlay1 (and this is the version causing issues)
xserver-xorg-video-intel ----> 2:2.99.917-1~exp1ubuntu2.2 (and this version doesn't seem to contain the fix)
