Currently using Ubuntu variants with Gnome3 as the default shell on all my workstations. Curiously, for laptops, the brightness control is always there.
I’m assuming that Gnome is somehow detecting the device has a battery that needs power management.
My issue here is that the brightness control is never visible for desktop PCs.
Any particular reason for that? Is it possible to enable this brightness control for any standard desktop PC? The obvious choice is to use tools like xrandr to adjust the brightness manually. But, seriously, I am actually tired of improvising ad-hoc scripts and installing 3rd party plugins for a feature that is clearly available in the native shell.
Major thanks in advance!
