Need Help setting up vnc4server for 2users pls

Im hoping you could help me setup vnc4server for 2users. I have setup ubuntu server at home and both me and a friend would like to login remotely, I have only installed vnc4server and tried to setup for both accounts but when I try connect from my notebook, using vncveiwer I get a greyish checkered screen with no desktop, just a small terminal window.

Im not sure were I messed up, and would really appreciate the help..

below is what I have done so far...

#sudo apt-get install ssh


#sudo apt-get install vnc4server

After it is installed you should be logged as normal user and not root.
#vncserver :1 -geometry 1024x768 -depth 16

the I killed the process using
#vncserver -kill :1

(***thats as far as I could get, after that the following command wouldn't work..***)

The configuration is kept in the file /home/userxx/.vnc/xstartup I edited this file so that I can start the server with gnome. My file looks exactly like below.

#!/bin/sh

and I didnt know were to enter the following...

# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

gnome-session &

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
# xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &


***I should add Im only new to ubuntu/ linux and have been using it to learn, for the last few month.. All help is greatly appreciated...

Thanks in advance
