Brightness controller can be installed, but fails to set maximum brightness.
screen is still not at full brightness, even though the brightness bar ist at 100%

I do understand your frustration with something that doesn't work for you, but you come two months after the fact and we're supposed to know one who you are, and two what your technical issue is? Are you certain these instructions match your issue?

Please make sure you read through Introduction to Hardware Support - Please Review before posting, as well as FAQ - Zorin Forum, and lastly Introduction to General Help - Please Review before posting - #3.

Now that there is some context and civility... welcome to the forum, how may I assist you?
