I recently started using Ubuntu and a like it a lot. However Windows in my Acer laptop had a function that made the graphics switch to a lower quality (or something) whenever I didn't have the charger plugged in.
In Ubuntu it doesn't seem work cause my computer is practically eating battery power. I guess this has something to do with the drivers, witch I heard is a bit of a problem in all Linux systems. Can it be solved in an not too advanced way?
I know many people have asked the same question and it looks like its solvable, but is there someone that could explain how to do it in a more pedagogic way? Because I don't really understand the answers to similar questions. I would appreciate it a lot.
