I want to mirror my internal display on the external HDMI port. On GNOME, settings reports “compositor doesn’t support wlr-output-management-instable-v1” and I can’t find a good explanation of the monitor.xml file format - if that is what needs to be changed.
Using Wayfire I have this in my wayfire.ini:
[output:HDMI-A-1]
mode = mirror DSI-1
transform = normal
But this leads to the wrong resolution on the HDMI port (640x480 ?) and the picture is 90 degree rotated.
I assume that someone has a working configuration because I am essentially just trying to show my desktop on a projector. So has anyone a working config? Or am I doing something wrong?
