OpenRazer

OpenRazer is in the official Ubuntu repositories, but it can be a few versions behind. We recommend using OpenRazer’s official PPA so you have the latest device support, features and fixes.

You’ll need to add your user to the plugdev group. Reboot afterwards for changes to take effect.

sudo gpasswd -a $USER plugdev
