VNC Server will not start
 

I'm trying to run VNC Server on CENTOS 7.

I had not problems installing the software however, I am having problem getting the VNC service to start. I'm getting the following errors below:

From CENTOS 7 system logs:

spice-vdagent

What could I be doing wrong that is not allowing the VNC Service to start.

Thanks

looks like it is disabled. which vnc is it? (realvnc, tightvnc, ....)

It's TigerVNC, you mention that it appeared to be disabled. I've made changes to the configuration and get the errors when I try to start it.

Any ideas why this is occurring.

Thanks

unfortunately I'm not really familiar with tigerVNC, but especially RealVNC wanted to create an account [free] in order to work... That was quite annoying....
