Title:
  drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in
  dpll_hw_state.wrpll (expected 0xb0210614, found 0x00000000)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This is a followup of
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1501260 .

  Basically, running OpenGL applications (e.g. glxgears) on the primary
  display handled by Intel 915 card results in display freeze. The error
  message from the title of this bug is written to a VT console if I
  switch to it. It seems this bug only appears when multiple monitors
  are connected.

  Switching to a VT (Ctrl+Alt+F1) and back unfreezes the screen for a
  while. The screen only looks frozen, but normally reacts to mouse and
  keyboard events. This only happens if the GL window is displayed on my
  primary display (which is handled by the intel integrated chip). The
  notebook has 2 video outputs and a discrete AMD graphics, and I think
  only one of the outputs is handled by the AMD card, so I think one of
  the outputs is handled by the intel card and does not get frozen.

  Ubuntu 14.04.3 64bit.

  I think that before upgrading from 14.04.2 to 14.04.3 this did not
  happen.
