I have no idea what your system is. I don't use MATE, so “screensaver”
doesn't ring any bell for me.

No idea, look at MATE documentation?

I'm not interested in nitpicking. LightDM didn't touch the brightness to

upstream call wether to implement this feature, so there's not much to
discuss here anyway.
