Public bug reported:
On the regular Ubuntu desktop I use an .xprofile with xrandr commands
that add the monitors native resolution as follows:
xrandr --newmode "3440x1440" 196.25 3440 3600 3952 4464 1440 1443 1453 1468
-hsync +vsync
xrandr --addmode HDMI-1 "3440x1440"
Unfortunately this doesn't work under wayland and I have not yet found a
solution. I have tried several ideas including a custom edid bin file
without success.
I'm reporting against the gnome-control-center since this corresponds to
the end user experience.
