I know with vnc you can access virtual desktops, but is there a way to view the current desktop on a kde session? I tried changing the .vnc/xstartup and added the startkde & at the end to get the gui working, but can only get virtual desktops to show. or if there is a different software to use that someone else might know about.
Umm...this isn't exactly what you are asking for, but it could be more of what you are looking for:
http://www.fedoraforum.org/forum/archive/index.php/t-1606.html (it's a fedora guide, but it works w/ CentOS, RHEL, etc.)
Basically it's a guide on how to setup vnc to talk to gdm. It's very cool. It allows you to connect to your machine via vnc, and have a regular gdm login screen. I find it very useful, because many of my end-users want a stinkin gui. =] And this way I can just run vnc from xinetd for all the users, instead of have a separate Xvnc process for each user.
