Bug Description
I have a Lenovo T440p laptop with a displayport monitor attached to the docking station. If I turn on the laptop in the docking station, the monitor works under the BIOS but once I get into Linux the monitor doesn't light up. I see the following in kernel log (full logs with drm debugging turned on via xdiagnose attached):
