I have Xfce over vnc mostly working.  Thanks to posts here.

I have a couple of open items.

My environment is Fedora29-beta 1.2 for armv7 with Xfce.  I have altered the
xstartup to end with:
I have just installed F29 Beta 1.5 in an VM on an x86_64 system.  (Sorry poc)
# exec /etc/X11/xinit/xinitrc
exec  /bin/sh /etc/xdg/xfce4/xinitrc
xrdb $HOME/.Xresources
startxfce4 &
I have not modified my /etc/X11/xinit/xinitrc file

Note that currently, the is no .Xresources file.
None here either.

In the log file, there are a bunch of sizing errors.  I suspect I need a GEOMETRY
statement?
None here.

When I connect to the user over vnc, I get my Xfce session with the XFCE -
PolicyKit Agent error.  This happens everytime I restart the vncserver service (or
reboot the system).
I use remmina as my vnc client.  When I connect, I get a desktop with no XFCE -
PolicyKit Agent errors.
I'm assuming you're using LightDM as your session manager for Xfce.
There is a known policy kit problem with LightDM and the kwallet system.

Please look at your "/etc/pam.d/lightdm" file and comment out any lines
that contain "pam_kwallet.so" or "pam_kwallet5.so" by prefixing them
with a "#" (there should be four of them, two for auth and two for
session).

If you're using SDDM as your session manager, this doesn't apply.
I am using lightdm.  I will test this tomorrow.
FWIW, the BZ Rick is referring to is https://bugzilla.redhat.com/show_bug.cgi?id=1581495

But, to see the problem one must also have pam-kwallet installed.  On my pure Xfce
F29 system...

[root@f28xfce pam.d]# rpm -qa | grep kwallet
[root@f28xfce pam.d]#

And, as I've noted, I'm not seeing any PolicyKit Agent error

I also do not have kwallet.  But I get the PolicyKit Agent error on a fresh system boot.  I looked into the service status and I see a line:

           ├─ 934 /usr/libexec/xfce-polkit

So perhaps the difference is running vncserver as a service and maybe the login is trying to start a second copy?

Next I need to build a F28 image and try that.  Meanwhile I will take this to the test list.
