I have to manually set my brightness because on a reboot Powerdevil will change it to something as low as 10%. My power profile is set to performance and don’t know why it would adjust my brightness like that. This didn’t start happening until recently. Anyone have an idea on how to stop it from changing my brightness?
Here’s a suggestion for working with brightness settings directly from the command line interface (CLI). This is a method I personally use. I’ve created a set of aliases for adjusting brightness, which makes the process both quick and efficient.
Here you go:
# BRIGHTNESS ALIASES FOR FISH SHELL
alias br15="brightnessctl set 15%"
alias br25="brightnessctl set 25%"
alias br50="brightnessctl set 50%"
alias br65="brightnessctl set 65%"
alias br75="brightnessctl set 75%"
alias br100="brightnessctl set 100%"
