Debian / Ubuntu

This guide covers Debian, Ubuntu and their derivatives (Kali, Parrot, Linux Mint, Pop!_OS...).

1. Install bspwmctl

Download the .deb from the latest release and install it:

sudo apt install ./bspwmctl_*_all.deb

As your normal user:

bspwmctl install --standard

Log out, choose bspwm in the session menu of your login screen and log back in.

Ubuntu: several packages (bspwm, polybar...) come from the universe repository. It is enabled by default, but if apt can't find them, enable it with sudo add-apt-repository universe.
Firefox (--all mode): Debian, Kali and Parrot get firefox-esr. Ubuntu-based distros already include Firefox, so bspwmctl doesn't install it there.
Linux Mint, Pop!_OS and other derivatives are not tested yet. They should work, and bspwmctl will warn you about it. Please report any problem.
