[fedora-arm] Can't start vncserver on F21

[Robert Moskowitz]

I followed information I found for using vncserver on a systemd setup:

#yum install tigervnc-server
#firewall-cmd --permanent --add-port=5903/tcp
#firewall-cmd --reload
#cp /lib/systemd/system/vncserver at .service 
/etc/systemd/system/vncserver@:3.service
#vi /etc/systemd/system/vncserver@:3.service
---now replace <USER> with rgm
#systemctl enable vncserver@:3.service

Created symlink from 
/etc/systemd/system/multi-user.target.wants/vncserver@:3.service to 
/etc/systemd/system/vncserver@:3.service.

#systemctl start vncserver@:3.service

Job for vncserver@:3.service failed. See 'systemctl status 
vncserver@:3.service' and 'journalctl -xn' for details.

# systemctl -l status vncserver@:3.service

I hd already run vncpasswd while logged in as rgm, thus creating the 
directory /home/rgm/.vnc and the file passwd.

So why is it not starting? What am I missing?
