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) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763202 Title: Lenovo X1 Carbon 6th Gen.
