Prior to this fiasco, I unplug the HDMI cable from the Librem Mini to connect it to a server I need physical access to. However, once the job done on the server, due to lazyness and an hdmi port, on the server, relatively difficult to reach, I use the cable connect between the second hdmi port, of the screen and my desktop PC. And this is were the troubles begin.
The port, used by the Librem Mini, is an HDMI 2.0. while the second port is an HDMI 1.4. For whatever reason, I didn’t think about switch ports on the screen side and this morning in a last desperate attempt to recover the situation, I finally unplug the HDMI cable from the server and connect it back to the Librem.
So I close the issue, really sorry for the disturbance.
I am having this exact problem with both my HDMI and DisplayPort video.
The effective disconnect of the video from the monitor happens via my 2 Anker HTML A/B splitters that have 2 in -> 1 out, where the in A on each is from LM v2 and the 1 out goes to my HDMI input to my monitors.
