Public bug reported:
My two external displayport connected displays worked fine until last thursday.
After bringing my laptop to the same HP dock station three days later, they
stayed blank no matter what.
Displays are seen by X (other of them was powered off during the bug report)
and detected correctly, but there is no picture.
Displays worked with the current kernel 4.4.0-92-generic on thursday.
Dmesg log is full of kernel errors from i915 driver, multiplied by me switching
the monitors on and off while troubleshooting the issue.
