I've installed vnc on Centos,...about 5 times now...
For whatever reason...this time... I get a black screen with big black x...and no Window manager.

I've followed the various wiki's and forums where other people have the same issue, but nothing is resolving it for me. I've installed this several times before but I don't remember it being this painful.

yum groupinstall "GNOME Desktop Environment"
yum install vnc-server

Service vncserver start

Then configured xstartup per the wiki...

...what gives?
I can SSH to the box, and i'm trying to install vncserver from command shell.
Each time I test with    192.168.8.253:1

...prompts me for pw,.... then black screen and black x...no GUI.

Not sure what other details I can provide.

Do you open for other VNC-like application?

I recommend NX nomachine.

Thanks, but I would like to stick with VNC, that's what I use for everything.

The reason I mentioned other product is because VNC is troublesome on modern Linux distros.
No new feature or improvement on VNC.
Most of time, you got disconnect and can not resume the connection (which is most important feature).

I tried on CentOS and Ubuntu and it just failed on me most of time. So I gave up and tried something much
better and reliable.

Can you try X on console for this machine?

Have you checked the logs in /var/log ?

parparov, ....thanks man!!!!!!!!!!!!!!!!!!!!!

I guess sometimes it just takes another person to ask an obvious question.

I examined the /var/log and didn't notice nay issues.... then I examined $HOME/.vnc/localhost.localdomain.log    ....and saw this:     Could not open Xstarup: Acess Denied

So I  did this...

CHMOD 777 Xstartup  
Then,
service vncserver restart

FIXED !!!!!!!!!!!!!
