Bismuth is a KDE Plasma extension, that lets you tile your windows automatically and manage them via keyboard, just like in classical tiling window managers (i3, dwm or XMonad).

Check out the source code at Bismuth’s Official Github

The source code for the Debian package files are located Here


There are 2 ways that you can install Bismuth on Debian based distros.

Volian Scar Repo

Install the Volian Scar repo and install kwin-bismuth

echo "deb http://deb.volian.org/volian/ scar main" | sudo tee /etc/apt/sources.list.d/volian-archive-scar-unstable.list > /dev/null
wget -qO - https://deb.volian.org/volian/scar.key | sudo tee /etc/apt/trusted.gpg.d/volian-archive-scar-unstable.gpg > /dev/null
sudo apt update && sudo apt install kwin-bismuth

deb Package

Download the deb package directly.

Install the .deb you just downloaded using the command below:

sudo dpkg -i kwin-bismuth_2.2.0-1_amd64.deb

If it mentions that there are dependencies you don’t have run the command below. Otherwise you’re good to go!

sudo apt install -f


There are many Debian based distros that this package may work on. It has only been officially tested on the ones below:

  1. Debian stable/testing/sid

  2. Ubuntu 21.04+

This will not work on Ubuntu 20.04 due to Plasma being just a little too old.
