Mine works well enough to run mythtv-setup or mythfrontend for setup (if I
want to actually read some of the tiny text or buttons that are lost in
overscan on my TV):
[mythtv at myth1 ~]$ rpm -qi vnc-server

Summary     : A VNC server.
Description :
The VNC system allows you to access the same desktop from a wide
variety of platforms.  This package is a VNC server, allowing others
to access the desktop on your machine.
OpenGL and XV don't work, of course, but the error messages I get are (this
is from starting mythfrontend):

DisplaResX: Unable to XRRgetScreenInfo
Xlib:  extension "GLX" missing on display ":1.0".

I'm using FC5 as you can see from the rpm output. I think the only other
thing I did here was install fvwm from tarball since I like it better than
twm. My usual vncviewers are various versions of tightVNC, but that probably
doesn't matter. Nvidia driver is 9746, x.org is 7.0.0.
