I used to access a remote system via VNC viewer, but when I copy some text from the remote system and paste it in my text editor(local system), nothing happens. Do I need to install any additional packages to achieve this task?

Updates:
There is no such option found in the Real VNC properties.

Screenshot

I just get the following output: 

karthick@karthick:~$ vncconfig         
No VNC extension on display :0.0

Updated: 

karthick@karthick:~$ vncserver

Warning: karthick:1 is taken because of /tmp/.X1-lock
Remove this file if there is no X server karthick:1

Warning: karthick:2 is taken because of /tmp/.X2-lock
Remove this file if there is no X server karthick:2

New 'X' desktop is karthick:4

Starting applications specified in /home/karthick/.vnc/xstartup
Log file is /home/karthick/.vnc/karthick:4.log

karthick@karthick:~$ vncconfig -display :1 
vncconfig: unable to open display ":1"

This is turning into a bit of a mess. Can you state somewhere what the setup is. What OS is the client? What OS is the server? What client and server software are you using on each? – Oli♦ May 27 '11 at 15:25
Client runs windows XP and the server runs ubuntu 10.10. And the client runs Real VNC and the server runs vncviewer. Do you need anyother information ? – karthick87 May 27 '11 at 15:31
vncviewer is not a VNC server (the clue's in the name :P) – Oli♦ May 27 '11 at 15:50
I have already installed vnc4server too. – karthick87 May 27 '11 at 16:07

There will be a .vnc directory in your home folder. In this directory there will be few files named like <computer name>:<number>.extension
For example my laptop contains following two files in .vnc directory. 

adnan-laptop:1.log
adnan-laptop:1.pid

The :1 in the above file names shows that the vnc server is running on display :1.

Now connect to your VNC server and from the connected session run vncconfig as follows:

vncconfig -display :1

This will show a small window with clipboard related options. Check all the options and dont close the window. Now you should be able to copy paste from/to remote system.

@karthick87: what command are you using to run vnc server? have you checked .vnc directory in your home folder? does it contain files like karthick:1.pid? – binW Jun 7 '11 at 11:14
Pls see the updates in my question.. – karthick87 Jun 7 '11 at 13:46
@karthick87: the output of vncserver says that "New 'X' desktop is karthick:4" so you should run "vncconfig -display:4" – binW Jun 7 '11 at 14:11
Now i am getting the following output, karthick@karthick:~$ vncconfig -display :5 No VNC extension on display :5 – karthick87 Jun 7 '11 at 14:20

It depends on the VNC client that you are using. If you are using RealVNC then open the VNC Viewer Properties dialog and, on the Inputs tab, turn on Share clipboard with VNC Server.

UPDATE:
Try this. Connect using vncviewer and run vncconfig within the remote window, check the options regarding the clipboard and then try.

@karthick87: you are looking at VNC server's properties. Go to VNC viewer's Properties dialog – binW May 17 '11 at 12:42
No its not there in VNC viewer properties.Look @ the snapshot pls. – karthick87 May 17 '11 at 12:54
@karthick87: I have updated the answer. Plz try the vncconfig method. I believe it will work because it has always worked for me. – binW May 18 '11 at 6:40
Do you want me to type vncconfig in command prompt ? – karthick87 May 18 '11 at 7:07

The VNC viewer you are using has to support this feature otherwise you're just copying it localy on the remote system.

Some commentary on your problem:
RealVNC's is proprietary and it's clipboard support may be entirely incompatible with tightvncserver. I've used both, together, in the past but I don't remember 100% if clipboard sharing worked bettween them.
I do know for sure that RealVNC-server paired with RealVNC-viewer did accommodate clipboard sharing; but RealVNC-server is not free (as in $$s)

You might try:
- tightvnc viewer from http://www.tightvnc.com/download.php It might be more compatible with whatever method tightvncserver used to share the clipboard.
-or-
- perhaps you could go with an alternate protocol, ie NX (nxserver/nxclient ... some info at: https://help.ubuntu.com/community/NomachineNX ). Clipboard sharing worked for me on that without any custom settings.

I use the following line in my login-script:

vncconfig -nowin&

Hope it works for you!?
