dmesg_drm.debug
I have issues when turning on external monitors on miniDP MST: the "secondary"
monitors of the MST setup doesn't turn on. I can turn it on by going through a
dpms cycle (waiting for power management to set both screens into dpms mode,
then move the mouse to exit dpms). Another way to turn the "secondary" monitor
on is disabling and re-enabling it once again.
I attached dmesg with drm.debug=14 and 4.8.0-1-drm-intel-nightly.</pre>
