well I’m happy you found a fix, I haven’t tried xbacklight but there’s also

dconf-editor

and the brightness applet on the panel. To add it: right click on a panel > add to panel > find and add applet.

Then you should be able to adjust as needed. There’s also RedShift but thats more about changing the color than brightness (and geared toward night time/ dark room users.)
