其实只要修改用户 .vnc目录下的xstartup配置文件即可
[root@localhost ~]# more /root/.vnc/xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
exec /etc/X11/xinit/xinitrc
将最后一样twm & 换成 exec /etc/X11/xinit/xinitrc 即可

继续启动vncserver，可能还有错误，如下
vncext: VNC extension running!

vncext: Listening for HTTP connections on port 5801
vncext: created VNC server for screen 0

xterm Xt error: Can't open display: %s
原因：vncserver默认寻找的X系统的字体路径在/usr/X11R6/lib/X11/fonts/下，但RHEL5却在/usr /share/X11/fonts/下
解决：mkdir /usr/X11R6/lib
cd /usr/X11R6/lib
ln -s /usr/share/X11 X11
