My screen brightness is set too high by default, and I cannot find any way to change it. The "Brightness and Lock" section in Settings does not have any brightness options. It just has options for turning off the monitor and screen lock. If I enable the Brightness applet it just says "Brightness not available".
I see some people have used step 1m here, viewtopic.php?f=42&t=86813 . However, my /sys/class/backlight folder is empty.
I am using a desktop PC with an AMD card, with Nadia-Cinnamon. I am using the default (open source drivers).
Does anyone know a solution?
