I have had this problem pre beta images.  This is the F29-armfhp code base.

I am running vnc server as a service.  I have edited the xstartup to have:

# exec /etc/X11/xinit/xinitrc
exec /bin/sh /etc/xdg/xfce4/xinitrc
xrdb $HOME/.Xresources
startxfce4 &

Note that currently, the is no .Xresources file.
I do not know why you're doing that.  But, I haven't.

When I connect to the system after a fresh boot or vncserver restart I get a dialog
with:

Error XFCE PolicyKit Agent

Ed Greshko reported on the Fedora list (as I thought this was a more general
VNC/Xfce error having nothing to do with the beta) that he does not get this error,
but he is NOT running vncserver as a service.  Rather from an SSH session.
I have configured by f28 system to run vncsever as a service and I see the error
you're reporting.

I believe I understand why the error is presented.

If you start the vncserver you'll see something like this

polkitd    706     1  0 22:31 ?        00:00:02 /usr/lib/polkit-1/polkitd --no-debug
egreshko  3527  3497  2 22:58 ?        00:00:00 /usr/libexec/xfce-polkit

running

When you make a vnc client connection, you get the error and then you'll see only

polkitd    706     1  0 22:31 ?        00:00:03 /usr/lib/polkit-1/polkitd --no-debug

running.  /usr/libexec/xfce-polkit has crashed.  Why?  I have no idea at 23:00.

Since I could not get my F28 working for vnc login to Xfce, I went back to my F29 image.

I disabled polkit startup in the Xfce startup widget and rebooted.

Now I don't get the PolicyKit error, but no change in being able to mount an USB drive or unlock printer config to add a printer.

So I suspect that Polkit should be left on in Xfce, but get the xstartup right so it does not also run polkit.

Which gets back to an earlier thread:

We DON'T know how to run DE other than Gnome for vncserver.  It would be very nice for some guidance on this.

And with this, past time to shutdown.  Catch you later.
