It worked momentarily but GNOME Shell locked up and crashed when I had an
application (Remmina) fullscreen in of the monitors.  This happens very
frequently in my experience.  GNOME just seems unstable on Intel HD 4600.
I even tried adding the following to my boot parameters but it didn't
change anything:

i915.semaphores=1
