latest updates to Ubuntu 16.04 cause logout on external monitor connection

Hi,

Exact same issue for me (XPS 9360, Ubuntu 16.04, did an apt upgrade and performance is now terrible).

glxgears is running at 1Hz (unless a part of the window is on the native screen). All the suggested hacks (adding options to /usr/share/X11/xorg.conf.d/20-intel.conf) do not work (I'm not sure how to check whether they are even applied).

My system was working fine and is now barely usable. Can you provide a fix or at least instructions to downgrade? Booting 4.4.0-72 kernel is yielding the same result, as stated by hinchliff.

Thanks
