How to rotate screen on wayland

I use gnome-randr. It "tries to reimplement some of the functionality of 'xrandr' for the gnome desktop using mutter's dbus-api. It currently has not been tested with fractional scaling support."

You can download it here : https://gitlab.com/Oschowa/gnome-randr Then you :

$ chmod +x gnome-randr.py

You can also replace the first line by this :

#!/usr/bin/env python3

and run it

$ ./gnome-randr.py

It will give you current configuration and names of your monitors, like DP-1 DVI-1 HDMI-1.

Then you can use xrandr syntax :

$ ./gnome-randr.py --output DP-1 --rotate left

Help is also available for all possibilities :

$ ./gnome-randr.py -h
usage: gnome-randr.py [options]
    where options are:
    --current
    --dry-run
    --persistent
    --global-scale <global-scale>
    --output <output>
        --auto
        --mode <mode>
        --rate <rate>
        --scale <scale>
        --off
        --right-of <output>
        --left-of <output>
        --above <output>
        --below <output>
        --same-as <output>
        --rotate normal,inverted,left,right
        --primary

When in KDE, you can use kscreen-doctor from libkscreen

as example:

kscreen-doctor output.1.rotation.left
kscreen-doctor output.1.rotation.normal
