Hi, the keys that control brightness weren't working for me. I tried fn +, CTRL +, alt + etc and those didn't work. So I tried to adjust the brightness in the Power Management settings, but there's isn't a setting for it. So then I found that you could add a brightness applet to the top panel, but when I added it is has a red cross-out over it and it doesn't work.
Any idea what to do? I'm on a Framework 13.
