Title:
  16.04 -> External Monitor not working -> radeon VCE init error (-110)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Since I've upgraded 15.10 to 16.04 my external monitor is not working anymore. Whether I plug it directly into the DVI port of my laptop ("HP EliteBook 840 G1") or whether I plug it into the DVI or VGA port of my docking station "HP 2013 UltraSlim-Dockingstation" I get the following error in "/var/log/syslog":

  I tried as well upgrading to the latest kernel as described here:
  https://wiki.ubuntu.com/KernelMainlineBuilds - latest v4.6 kernel[0]
  But this did not help either.
