Debian

1. OpenRazer

First, you’ll need to install OpenRazer. Packages and instructions can be found on the openSUSE Build System.

For original instructions, see the OpenRazer website. Be sure to restart the computer after installing.


2. Polychromatic

The packages are built for compatibility in both Ubuntu and Debian. To ensure the latest updates, add the repository and signing key as follows:

echo "deb http://ppa.launchpad.net/polychromatic/stable/ubuntu xenial main" | sudo tee -a /etc/apt/sources.list.d/polychromatic.list
sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 96B9CD7C22E2C8C5
sudo apt-get update
sudo apt-get install polychromatic

For development builds (which may be unstable and cutting edge), replace stable with daily.

Alternately, .deb files are provided in the releases notes.
