Public bug reported:
Hello,
I've been made to understand that brightnessctl should not require root
privileges to effectively modify the screen's brightness, but ubuntu's
version still is not usable without tweaking the environment a bit.
According to the readme, 3 ways are available, but the least demanding
for users would be to enable the systemd-logind API in the binary, no
longer requiring users to add themselves into the video/input groups,
nor having the binary as a setuid binary.
It seems this should be doable through the update of the compilation
options of the binary, via the make define `-D ENABLE_SYSTEMD`. That
being said, for future proofness, brightnessctl's master branch seems to
rely on a new approach based on a configure script which takes a CLI
option instead.
