Public bug reported:
When resuming my laptop from sleep via the keyboard, occasionally X will
freeze up - this is usually associated with one of my monitors not
displaying output. I can't reach a terminal with Ctrl-Alt-F2 and I have
to open the laptop and reboot with Alt-PrtScr-(REISUB) (hard reboot) -
the USB keyboard won't work in this situation.
This only happens occasionally and will usually happen if I wake the
laptop before turning the screens back on.
There are other cases that can also trigger X freezes but I'm not sure
if they are related (eg. unplugging screens).
The following is commonly seen in dmesg during normal behaviour:
[drm:intel_dp_aux_native_write] *ERROR* too many retries, giving up
[drm:intel_dp_start_link_train] *ERROR* failed to enable link training
