πŸŽ‰ To start using Bismuth enable it in System Settings > Window Management > Window Tiling. Additionally, you can decorate your windows in a tiling window manager style (border-only windows) using the window decoration, that comes with Bismuth. To do so, go to System Settings > Appearance > Window Decorations and select the Bismuth decoration.

⌨️ You can view the shortcuts in System Settings > Shortcuts > Window Tiling. If you used Krohnkite before, you can import some of its shortcuts using the bash script.

πŸ”§ If you want, you may also make a couple of manual fixes and tweaks to improve your experience with window tiling. See Tweaks section.


You can configure Bismuth in the System Settings > Window Management > Window Tiling.
