Hotkeys to adjust brightness
Are these hotkeys available under Linux? The default key combo used in Windows doesn't seem to work.
As a workaround, is there any way to activate manual controls from the console?
I had the same problem on Windows. I would hold down Alt + PgUp/PgDn and nothing was happening. But the solution was simple I just had to hold the Fn key as well! I hope that works for you too.
