Okay, I followed the directions at
http://wiki.centos.org/HowTos/VNC-Server
and I can now vnc in after boot up and I get a gnome login screen. Wonderful. I can open applications and what not, but then I tried to add a new user via the gui "system-config-users". It prompted me for the root password and then no window. I try to run it from the cmd line via sudo and get the following:
Xlib: connection to "couch:1.0" refused by server
Xlib: No protocol specified
system-config-users requires a currently running X server
Yeah, the laptop is called "couch". Anyways, um, I'm obviously running an server so what gives?
