dmesg of 5.0.0 drm-tip failing to wake up external monitor, failing once when
forcing mode with xrandr, then succeeding the second time
This dmesg log shows the following sequence:
1. locking gnome-shell, which puts the monitors in standby mode
2. after a while, returning to the laptop and resuming work : the external
monitor tries to wake up but fails and returns to sleep
3. after a couple of minutes : forcing mode with xrandr : external monitor
tries to wake up, but this time it fails and returns to sleep... again
4. after a couple of minutes : trying to force mode with xrandr a 2nd time :
this time it succeeds</pre>
