No .desktop file for policy kit? Source is very small, so I could add it to gnome-flashback module... How it is autostarted? What it does? It would be nice to give some steps so I can easily verify if works or not.

They removed the autostart file, and let desktop environments to autostart it when it's needed.[1]

Thanks!

Note that polkit-gnome is still used by Cinnamon and Xfce on Arch Linux[2] and Fedora[3]. Debian also has a downstream autostart file.[4] There is also a request for MATE to use polkit-gnome instead of their fork[5]. So forking polkit-gnome is not the best solution I think.

I am already working on libpolkit part in gnome-flashback. If someone will start to maintain that module then we can always switch back to it. Right now I am only interested to get it working in gnome-flashback.

You could easily test if it works or not when you do something that requires root privileges via polkit. E.g. run the 'gnome-control-center user-accounts' command, and click on the unlock button. If a graphical polkit authentication agent is running, then you'll see a dialog asking your password. Without that, you won't see the unlock dialog, and not able to do privileged actions.

Thanks!

GNOME devs don't want that gnome-screensaver is maintained - they suggested to fork/rename to gnome-flashback-screensaver. But in this case I simply better integrate it in gnome-flashback module.

I really hate their decision just because naming issues. We should avoid fork if possible as Xfce[6] (xflock4) and LXDE[7] (lxlock) are still use gnome-screensaver optionally for their screen locking feature. It's even useful within GNOME Shell, because its integrated lock screen works only when GDM is the configured display manager.
