> But it can't decrease brightness

Who said that? You can always decrease brightness on a Linux laptop since the first gnome, I myself have gnome3 installed on 2 laptops and the brightness buttons are working perfectly fine.

I could never adjust the brightness of my laptop under Linux. So many people defend Linux to the point of denying people's first hand experience with it.

Didn’t work on my old Toshiba Satellite either. It wasn’t a particularly unpopular piece of hardware or anything.. actually it couldn’t even read the battery % due to an ACPI issue.

The buttons do work. But, some monitors are still too bright at night even with that brightness set to minimum, and hardware monitor controls set to minimum too.

Redshift manages to decrease brightness even further.

He's saying that the Gnome night-mode doesn't adjust brightness ... not that it can't be changed at all.
