Awesome
A dynamic window manager for the X Window System.
Installation
On Debian, the window manager and a bare X:
sudo apt install awesome termit xorg
Then add the following to .xinitrc:
exec awesome
Copy the default config somewhere you can edit it, and install the quality-of-life programs my config expects:
mkdir -p ~/.config
cp -r /etc/xdg/awesome ~/.config
sudo apt install adwaita-icon-theme brightnessctl playerctl xsel
