GNOME:
[Root @ test vnc-4_1_2-x86_linux] # vi/root/. vnc/xstartup
#! /Bin/sh
[-R $ HOME/. Xresources] & xrdb $ HOME/. Xresources
Xsetroot? Solid gray
Vncconfig? Iconic &
Xterm? Geometry 80x24 + 10 + 10? Ls? Title "$ VNCDESKTOP Desktop "&
Gnome-session &

KDE:
[Root @ test vnc-4_1_2-x86_linux] # vi/root/. vnc/xstartup
#! /Bin/sh
[-R $ HOME/. Xresources] & xrdb $ HOME/. Xresources
Xsetroot? Solid gray
Vncconfig? Iconic &
Xterm? Geometry 80x24 + 10 + 10? Ls? Title "$ VNCDESKTOP Desktop "&

Restart VNCServer after modification.
[Root @ test vnc-4_1_2-x86_linux] # vncserver? Kill: 1 & vncserver: 1
[Root @ test vnc-4_1_2-x86_linux] # vncviewer 192.168.98.32: 1

After the connection, you can use GNOME or KDE Desktop (like WinXP Remote Desktop). You can also access it through the WEB and enter http: // 192.168.0.252: 5801 in the browser, the default VNC port is 5801.
