Ever wanted to control the brightness of your multi monitor setup independently but from the same place?
I know some of you reading this do as you’ve previously mailed in and asked if we knew of a solution.
Well, we found one.
Brightness Controller is a small tool using Xrandr to let you independently adjust the brightness of your primary and external monitors.
Not being a multi-monitor user myself I can’t confirm how well this app works; or whether it’s a software-based dimmer. But if you think it’d be useful you can find more information on how it works and how to use it on the Github page for the application.
