Disable Screens and switch input

Using wayland it isn't possible to use xrandr so a small script called gnome-randr.py. Also this script needs the user session, so I use a small hack by ssh into my user and run the scripts.

Two of my screens don't like it if there is more than one video signal, so I disable the output. After that with the usage of ddcutil the input is switched for all displays.

After the VM is shutdown the screen input will be re-enabled and the input switched.

ddcutil

Needs the module i2c-dev to be loaded.

• Can be done manually by running sudo modprobe i2c-dev
• or can be loaded at boot
  • add i2c-dev to the file /etc/modules-load.d/modules.conf
