Description of problem:
XFCE doesn't start any authorization agent.
Version-Release number of selected component (if applicable):
I've installed rawhide without in minimal install (without any graphical environments) and later decided to $ yum groupinstall XFCE - and there was no auth agent running, so apps like PackageKit are not able to show the PolicyKit auth window. I had to manually run /usr/libexec/polkit-gnome-authentication-agent-1. Or is there any xfce-auth-manager that I forgot to install?
polkit auth window doesn't appear when user needs to escalate his privileges
Auth window appears when it's needed
Adding some auth agent to xfce autostart could fix (or workaround) this.
This is due to /etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop
1) Just add 'XFCE;' in there.
2) Just remove the OnlyShowIn line entirely. Are there any other polkit agents that exist and are used currently?
Moving over to polkit-gnome for comment...
I removed the line
