vncserver finally works on my ubuntu 14.04

Finally, the VNCServer works for me on my Ubuntu 14.04.
As I experienced before in Ubuntu 12.04 and other dists, the VNCServer is a good choice to control computer remotely. However, it's changed since I installed Ubuntu 14.04. I can NOT get the "Desktop" when I use the same configurations. After searching, I found the solution!

Generally, install vnc4server first:

# apt-get install vnc4server

Install more:

# apt-get install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal

First start up, I prefer use :1:

# vnc4server :1

and then kill it:

# vnc4server -kill :1

update the xstartup:

# vim ~/.vnc/xstartup

replace the content with the following:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

#!/bin/sh

export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &

gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal &

then, restart vnc4server:

# vnc4server -geometry 1280x800 :1

use vncviewer connect to this server ip, xxx.xxx.xxx.xxx:1!
