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.
