I wasn’t able to get my HDMI output running on my Lenovo X1 Carbon 6th gen today. I run gnome on Wayland. It has been working fine for the last few days but completely dead today.
Did an update affect anything? I'm using Driver "intel" However, the "Multihead" Wiki, https://wiki.archlinux.org/index.php/Multihead, refers to "Related articles" for non-Intel.
Symptom: The external display detects that an HDMI cable is connected (via ground?) but there is no signal.
Maybe no signal, but perhaps just +5 V, https://en.wikipedia.org/wiki/HDMI.
Here’s what I tried: Switch from wayland to Xorg [snip] Looking at xrandr => Not connected
But xrandr shows one or more disconnected HDMI ports? $ xrandr | grep -i hdmi HDMI1 disconnected primary (normal left inverted right x axis y axis) HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 530mm x 300mm
