I use either Ubuntu or Gentoo and I never had this problem, I take it 
you use Redhat?

Typically I would set some kind of X11 implementation on the local 
desktop machine and using ssh -X (or the equivalent) I would connect to 
the remote host.
Not all the desktop of the remote machine will be available on the 
desktop of the local machine. Typically I would launch specific 
applications on the remote that will show the display on the local and 
in that case I typically like the local desktop to rule.

I was not successful with vncserver as plane user. Always as root.

I believe that X11 protocol is more efficient than image transfer as VNC 
does.

Never tried that. Sounds interesting. Will try it next time I have to 
use this kind of setting.
