i have added the brightness icon to the top panel but when adjusting the percentage nothing affects the screen. the mate power manager package is installed.
There is similar issue with Mint. There is not yet any official fix for this, but on Mint this was solved by installing applet for this. I am not certain if you can do this on MATE also. It is called Brightness and Gamma in Mint.
two cents:
inconsistency like this is what made me ditch any DE’s brightness offerings long ago, and just install redshift every fresh install.
redshift -O 4000 (number of my choosing) puts me where I want to be, when I want it. --a workaround to be sure but no more struggling

i have installed redshift and added a config file for it in which i set the brightness to 0.8 and it was changed after that. but now the brightness is fixed in that value, i may need to change it sometimes.
@ardv,
In an Ideapad it works with Kernel: Linux 6.6.62-1-lts. And Fn+F11/F12 as well.
Try
yay -S brightnessctl
brightnessctl s 15%+
brightnessctl s 15%-
Should it work assign them with
mate-keybinding-properties
to keyboard shortcuts.
I do that changing on the fly with that command. when it’s cooperative. I have Cinnamon and I can’t get their brightness applet to work so redshift all I got. I wonder what else is out there via AUR? someday.
ps—budgie the only DE with a reliable brightness applet that I’ve tried (I haven’t tried every DE of course)
KDE brightness control is working well with me (not in the desktop laptop that i’m having the problem with mate brightness)

(have not run kde as a DD yet) as I still have love the old gnome-based stuff, still. even XFCE too kind of although in XFCE I cant remember finding one, or in MATE as you have established, and I am officially digressing
