If you're using 18.04 now then you're not using the HWE hardware stack anymore so if there is an issue there (18.04) maybe new thread.

Good point. I gave this thread a new title and added a note in the first post that I'm now using 18.04.

Well I guess xcalib can only work with the intel driver (xserver-xorg-video-intel) rather than the current default of the builtin modesetting driver.
When's the last time xcalib was updated? (seems pretty old..

[halogen2]

Huh, for some reason I thought Ubuntu was using this version of xcalib. Looks like the version of xcalib that Ubuntu is packaging was last updated in 2008!

Do you know of another program that can apply a .icc file from Mac OS to my display at LightDM setup?

Maybe try the latest release from github (0.10). Should only take about 10 sec. to make & install.
I don't have apple hardware nor a monitor to calibrate, ect. but the 0.10 seems a bit more compatible, notice Xrandr & Xrender 'support' in newer version

(- if building make sure you have libxxf86vm-dev, libxext-dev, libxrender-dev, libxrandr-dev, libxcb1-dev installed

Success! The version of xcalib I linked above works without 20-intel.conf, and so I now have my brightness keys back!

Thanks mc4man for your help!
