Public bug reported:
Using the Ubuntu 20.04 settings app to setup multiple monitors creates
broken xrandr settings. Using the app to set a 3840x2160 primary monitor
in Landscape and 1920x1080 in Right Portrait, the primary monitor ends
up with a "virtual resolution" of 4680x2160 which creates a horizontal
panning effect at the monitor boundary and pushes the secondary
monitor's content far off to the side.
Running xrandr shows the following (truncated for readability -
screenshot attached)
Screen 0: minimum 8 x 8, current 5760 x 2160, maximum 32767 x 32767
DVI-D-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 connected 1080x1920+3840+0 left (normal left inverted right x axis y axis)
527mm x 296mm panning 1920x1920+3840+0 tracking 5760x2160+0+0 border 0/0/0/0
1920x1080 60.00 + 60.00* 59.94 50.00 23.98
...
DP-3 disconnected (normal left inverted right x axis y axis)
DP-4 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis)
697mm x 392mm panning 4680x2160+0+0 tracking 5760x2160+0+0 border 0/0/0/0
The correct result for DP-4 would be 3840x2160. I will set this manually
but wanted to report the problem.
