    This is the wrong site for this question. StackOverflow is about software development. This seems like a better fit for Super User or Unix & Linux SE. – 0xLogN Apr 13 '22 at 18:13

The brightness keys don't really work when installed. You can tinker with acpi_ibm(4) and acpi_video(4) if you're interested.

Brightness can be increased or decreased with backlight -f /dev/backlight/backlight0 incr [value] and backlight -f /dev/backlight/backlight0 decr [value] respectively. Check the man page of backlight for further information.

Add a key binding to make it work like fn keys.
