Whenever I plug or unplug the laptop charger the brightness changes to a very low setting. Does anybody have an idea of to prevent these kinds of changes?

Have you checked Gnome’s Power settings ?

Yeah, I’ve checked that. Nothing about changing brightness when the charger is plugged or unplugged.
