I just installed Fedora 36 and the brightness hotkeys show weird behavior:
Pressing the “Brightness UP” key once takes the brightness to Maximum no matter where the brightness initially was.
Pressing the “Brightness DOWN” key once takes the brightness to Minimum.
In a fresh boot, after pressing both the keys, each once, None of them work again i.e. pressing them again doesn’t do anything.
I can still change brightness through the top bar using slider.
I tried installing Pop shell, which altered the keyboard shortcuts but then I uninstalled it and reset all “Keyboard Shortcuts” from the GNOME settings.
PS: “mod + L” to lock the PC, was also not working but it started to work after resetting keyboards shortcuts.
Any help is appreciated, I’m ready to get my hands dirty with terminal if needed.
