Gaming on Linux is big business now, and many ardent gamers use a Razer keyboard or mouse.
Razer doesn’t offer any Linux support itself, preferring to leave the nitty-gritty to the open-source community — which many awesome individuals have dutifully done for several years.
Polychromatic is a neat desktop app for managing Razer keyboard and mice on Linux. The app, created by Luke Horwell, is powered by the open-source Razer Chroma Linux Drivers daemon.
Kubuntu council member Aaron Honeycutt came across the tool while trying to get his Razer Blackwidow Chroma keyboard to play nice with Ubuntu.
It supports a number of Razer Blackwidow peripherals, including the Blackwidow Chroma, Ultimate 2013 and Classic keyboards, and the Mamba mouse.
