### 2. If you have this problem after fresh installation: 1. How did you create USB bootable? - PendDriveLinux - Booted intro live mode and installed from live mode onto a partition 2. How did you install OS? - Debian installer My brightness control does not do anything. When I attempt to adjust brightness from the keyboard, the GUI responds and shows the brightness bar moving but the screen brightness remains the same unless I drop it to zero at which point the screen goes dark. I can adjust the screen brightness from terminal using: xrandr --output eDP-1 --brightness and then inputting a value between 0 and 1. I have made sure the system is fully up to date but I am brand new to linux and haven't manage to track down why the brightness will not change from anywhere but within terminal. Would love some assistance if anyone has seen this problem before or has an idea.
