I recently installed Ubuntu 18.04 on my Asus laptop with NVIDIA graphics and an Intel i5 CPU. ASUS ROG G531GD
I accidentally decreased my screen brightness to 0 in the battery settings before I could configure the Fn keys (they do not work by default).
So I restarted and shifted to console mode when the login screen appears by pressing Ctrl+Alt+F1 and after logging I insert the following command
xrandr | grep " connected" | cut -f1 -d " "
Can't open display
I also tried to blindly type in terminal the following:
xrandr --output "$(xrandr | grep " connected" | cut -f1 -d " ")" --brightness 1. nothing changed
How do I use the console mode to change my brightness level considering that xrandr wont work.
I can log into recovery mode.
