[Bug 1813910] [NEW] Multi-monitor setup crashes laptop

Public bug reported:

I have an HP laptop in a docking station.
It has been working fine for months, but now it crashes and I have to hold the power button to restart. Black screen.

Example 1:
The PC is docked, lid closed. I turn it on, login and the two external monitors go black.
Restart PC but holding power button. (Undocking / Opening the lid does nothing)

Example 2:
The PC is docked, lid open. I turn it on and login.
When the desktop is loaded, I close the lid. The two external monitors go black.
PC goes black, does not respond.
