In https://github.com/NixOS/nixpkgs/issues/100119 pantheon's greeter has g-s-d running which allows brightness controls via pkexec. This is changed in newer versions of g-s-d (pantheon uses a fork currently), but whenever brightness is changed with a shell of `shadow` we get ``` Oct 10 23:51:44 kirXps pkexec[18722]: lightdm: Executing command [USER=root] [TTY=unknown] [CWD=/var/lib/lightdm] [COMMAND=/run/current-system/sw/bin/elementary-settings-daemon/gsd-backlight-helper /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight 65587] ``` I'm not sure this should be strictly needed, so we should try to revert later on when pantheon's g-s-d is updated.
