GPU crash dump saved to /sys/class/drm/card0/error

Currently everytime the machine wakes from suspend, the login screen appears
but it does not work. I wait a little.
Sometimes it blinks and the login screen comes back to normal (I can type my
password in the login box, wifi is connected in the network menu).
But sometimes, a message about "runnning in low graphics mode" appears. It
is possible to click OK and then the normal login screen comes back -- it may
be necessary to click OK more than once.
This is on Ubuntu 16.04.2

Reminder of dmesg:
[50157.082931] [drm] GPU HANG: ecode 7:0:0x86ffbff9, in Xorg [11890], reason:
Hang on render ring, action: reset
[50157.082933] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[50157.082933] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[50157.082934] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[50157.082934] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
