This xserver doesn't load the intel driver anymore on gen4 and newer.
You can get previous behaviour back by copying the template xorg.conf
from /usr/share/doc/xserver-xorg-video-intel/xorg.conf to /etc/X11 and
restarting lightdm etc.
it could be a kernel bug though
** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu)
** Changed in: xorg-server (Ubuntu)

Title:
intel driver (intel_drv) not loaded
Status in xorg-server package in Ubuntu:
Confirmed
Bug description:
Hi,
just upgraded and rebooted (been quite a while since I rebooted so lots of
things probably changed in the mix).
The system initially logged in and my screen layout was lost (instead
ie, the monitor on the left was on the right). I changed that back,
logged out and back in.
Now, occasionally and seemingly randomly the larger display goes black for
1-2 seconds during usage.
It often occurs when switching desktops via hotkeys, but sometimes at other
random points.
