[SOLVED] Two external monitors (2x HDMI over USB-C) - lid close

Hello,
I have a X1 Carbon 5th generation and had until now one external hdmi monitor connedted to it. Now I got another external monitor,  and got an USB-C -> dual HDMI connector.

If I plug everything in the external screens both get detected, but when I close the lid, there remains just one external monitor detected, the other one gets black.

I tried it on both a gnome 3 Wayland and xorg session, but if I close the lid one external monitor always gets black.

What works is disabling the internal monitor and just enabling the external monitors, but then the laptop has to be open all the time and since I lack space, that's not an optimal solution.
Any suggestions?

Greetings

matse


//EDIT: Solved. Managed to enable both displays unter xorg via xrandr and finally found the setting to enable the 2nd external monitor under Wayland with the gnome control center (didn't know that actually the "label", which displays the monitor name is a button, on which you can click and enable the monitor...)
