Adjust the screen brightness in Emacs If you're using i3wm on Linux, how do you adjust the laptop's screen brightness? Most of the time, I use the laptop with an external monitor.

I have been really enjoying the more concentration workflow qtile, a tiling window manager, brings me, since I started using it a few months ago.
