Public bug reported:
My laptop (Lenovo ThinkPad P51) has 2 display interfaces. One mini-dp
and one HDMI. But none of them is shown in xrandr, and my external
display connected through mini-dp is not detected also.
When I used LiveCD, the external monitor works normally. The above
situation happens when my boot from SSD with the fully-installed system.
