I confirm that 'xbacklight -set 60' works (as user, no root required), in both desktop sessions: ubuntu and plasma. However, the Fn key + arrow only works on plasma. Being on ubuntu session, inside the directory '/sys/class/backlight' there is nothing, yet xbacklight works. So it's almost sure a gnome/wayland whatever issue.

[Bug 1720438] Re: brightness control broken nvidia
If your backlight is wired through Nvidia then I think you may need to use the xbacklight interface. You can do it manually by installing: sudo apt install xbacklight and running xbacklight ... If that works for you then I think the problem is that mutter/gnome- shell isn't using/supporting/checking the X backlight interface.

Ok tried several graphical environments with the line "WaylandEnable=false" commented and uncommented, and the proprietary nvidia graphics driver, and those are the results: - Desktop Session: Ubuntu: Fn to control screen backlight doesn't work in any case, neither line enabled nor disabled. - Desktop Session: Ubuntu on Wayland (Wayland): can't even enter to the desktop in either case.
