How to set the WAYLAND scaling of the display through command line?

Question

The same as this, but for Wayland. I want to switch between 100% and 175% using command line.

Answer 1

I'm using wayland under Ubuntu 24.04 and:

https://github.com/jadahl/gnome-monitor-config/

This worked fine for me (you'll have to build it yourself with meson, sudo apt install meson).

gnome-monitor-config list 

This gave me the name of my display (DVI-I-1 in my case)

Scaling is set with the -s switch, so to set scaling of 3 we do:

gnome-monitor-config set -LpM DVI-I-1 -s3
