Allow only physically connected users to use brightnessctl about brightnessctl HOT 6 CLOSED

It would be great

Why?

from brightnessctl.

In the case where I share my laptop with my friends both physically and over SSH. It is a nonsense to allow a user remotly control the the brightness since he probably doesn't even have the necessary permissions to output something to the screen.

My goal is to have a dynamic permission system a bit like with the uaccess tag of udev/systemd.

And since DBus is highly configurable, we could have users that always have access to the backlight (root for example, or let the machine administrator choose).

But that'd require depending on dbus, yuck

@xdbob I'm sure you can mess around with polkit to achieve this.
In addition, you can only add your local user to the necessary group.
It's not like you can prevent your friends from doing anything, if they can sudo.

I have a polkit policy for something like this. I wrote it for light though. See the annotate key field for where the binary path goes.

PolKit might do for a single seat configuration. I will look into it thanks for the feedbacks.

PS: The ideal situation would be ACLs support in the sysfs and let udev/systemd work out everything for us
