Hi All,
Coming in the next regen of meta-repo are ebuilds and supporting tools for configuration of Razer (https://www.razerzone.com/) keyboards and mice. This allows you to create neat glowy and color effects, as well as do other useful things.
To configure your Razer devices, first perform the following:
# emerge polychromatic
# reboot
Then, you will need to add your desktop user to the plugdev group, and then start openrazer-daemon in your personal .bash-login or .xprofile:
openrazer-daemon
At this point, you should be able to run polychromatic controller in your desktop environment to configure your Razer devices.
