How to Install a VNC Server in Ubuntu

1Open a Terminal window. The Terminal window can be found under "Start" > "Utilities."2Download vnc4server and xinetd:
sudo apt-get install vnc4server xinetd3Start the vnc4server:
vnc4server

You will be prompted for a password. This password will be used to log into the VNC session.

After providing a password, you will get output that looks like:
New 'laptop:3 (laptop)' desktop is laptop:3

Take notice of the number after the colon (:), in this case it is "3."

Starting the vnc4server will cause a .vnc directory to be placed in your home directory.4Stop the vnc4server
vnc4server -kill :3

Replace the number "3" with the number from Step 3.5Open the .vnc/xstartup file for editing:
gedit ~/.vnc/xstartup

The file will look like:
#!/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 ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &6Change the .vnc/xstartup file and save it.

Uncomment the lines that start with unset and exec. Comment out the lines that start with xsetroot, vncconfig, xterm and twm.

The final file should look like:
#!/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 ] && xrdb $HOME/.Xresources
#xsetroot -solid grey
#vncconfig -iconic &
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &7Change the permissions on the /etc/X11/xinit/xinitrc file to make it executable:
sudo chmod 755 /etc/X11/xinit/xinitrc8Start the vnc4server:
vnc4server

Again, remember the number after the colon (:).9Log into your remote desktop to check the configuration:
vncviewer localhost:3

Provide the password that you chose in Step 3.
