Thank you. You are correct for GDM. Adding this fixes changing the backlight in GDM. Perhaps the GDM service should extend the polkit service like that. It also does not conflict with adding a gnome-service-type. MATE still complains. Without changing services, normally both on the first log-in to MATE and on subsequent log-ins, when pressing the keys to change the backlight, a message window still tells me that /gnu/store/5kmmwc9q23lihpy3nv2knbvsr9qv2aln-mate-power-manager-1.24.2/sbin/mate-power-backlight-helper needs to be authenticated as the super user; I need to enter the password. Only with gnome-service-type and when not removing the GDM service, after GDM (which uses the gsd), on the first log-in to the MATE desktop, the backlight keys do nothing at all. When I try to log out, it says Power Manager is not responding. When I force the log-out despite the Power Manager, then log back in, I again get the message each time I press the backlight keys. I added: (simple-service 'mate-power-polkit polkit-service-type (list mate-power-manager)) It does not work. Regards, Florian

Should the MATE service do the same? To work around it locally, try adding: (simple-service 'gsd-polkit polkit-service-type (list gnome-settings-daemon)) to the (services ...) section of your system configuration. signature.asc Description: PGP signature

I’m reopening this bug because it is very similar to my issue. When using my Macbook’s keyboard XF86MonBrightnessUp/Down keys to adjust screen brightness (probably on non-Macbooks too) in GDM or MATE, I am asked to enter my authentication password to make gnome-settings-daemon’s libexec/gsd-backlight-helper (or some equivalent program on MATE) change screen brightness. This should not be so; gsd-backlight-helper should have PolicyKit, pam or setuid or whatever. Regards, Florian
