An old thread, I know but I've experienced similar problems.
After upgrade from Ubuntu 14.04.3 to 16.04.1 with Xmonad window manager
certain undesirable symptoms began to arise. Of course, fglrx was be
removed and the xserver-xorg-driver-ati(?) graphics driver was installed
instead. In 14.04 I was running the proprietary driver for the Intel
part of the hybrid card. After upgrading some icons appear very large
while others are normal. The laptop also runs about fifteen degC hotter.
This is the most troubling aspect as it is detrimental to the health of
the machine.
I reverted to Ubuntu 14.04.3 with linux-image-xxx-lts-wily as the latest
combination of Ubuntu and linux kernel compatible with fglrx. All very
well until dirtyCOW arose, as this kernel is no longer supported.
Question: Is this problem related to the others mentioned in this
thread? Has there been a resolution since July 2016?
The following information may help:

Am I right in understanding that though the radeon kernel module is loaded it
is not being used? If so, what must I do to use it?
