Public bug reported:
I have an X1 Carbon 6th Gen. (Intel Core i7 8th Gen, 16 GB RAM, 512 GB
SSD).
When I try to attach an external monitor via an HDMI cable the monitor
receives no signal. Similarly, when I use the Thunderbold dock and
attach two monitors (one via HDMI, one with DisplayPort) only the
monitor attached with DisplayPort works; the monitor attached with HDMI
stays black.
This made me think if this is really a bug in the software. I saw people
describing this issue with Windows installed; the solution was to hit a
special key combination. Unfortunately, the multimedia keys all not all
functional, specifically the F7 key, which seems to meant for "activate
external monitor", has no function.
** Affects: linux (Ubuntu)
