I am using Fedora 38 on Wayland. I need to switch a secondary monitor on and off using shortcuts, and kscreen-doctor seems to fix the bill.
I can successfully turn outputs on and off, however this seems to reset the geometry (as in screens now copy each other). Yet while I can see “Geometry” in kscreen-doctor output I can’t find a way to set it at all.
The output for DP-3-3 says: Geometry: 0,0 2560x1440
I need the screen to start at 1920,0 instead of 0,0, so I try commands…
$ kscreen-doctor output.DP-3-3.Geometry 1920,0
Unable to parse arguments: output.DP-3-3.Geometry
$ kscreen-doctor output.DP-3-3.Geometry.x 1920
Unable to parse arguments: output.DP-3-3.Geometry.x
How do I actually make DP-3-3 start at 1920,0 in this example, so that the other screen is “to the left” of it and not copying it?
…or maybe I should just use xrandr? It seems to work, as in
$ xrandr --output DP-3-3 --pos 1920x0
