SUMMARY

Splitting a big screen into 2 or more virtual screens with `xrandr --setmonitor` doesn't work in kde. Although the commands work. Obs studio for example recognizes the 2 monitors, kde doesn't.


STEPS TO REPRODUCE
1. run `xrandr --setmonitor virtual-1 1920/437x1600/366+0+0 HDMI-1`

OBSERVED RESULT

nothing happens

EXPECTED RESULT

the screen size is changed to the size of `virtual-1`

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.26.5

Setting virtual monitors through external tools is unsupported in Plasma

Comment 2 thomas coopman 2023-01-31 08:55:00 UTC

Ok, so I guess this will never be supported?
