Thanks Niles.  Eventually I will buy a kvm that supports my dvx monitor, but
till then I'm stuck with using vnc and ssh so I don't have to crawl under my
desk every five minutes :)))

It's even easier if you use the GUI (system-config-securitylevel or

FreeNX is not a VNC server. Both provide remote GUI access though. See  
'yum --help', the command is remove, not uninstall.
