RandR extension missing

Help!

I have a linux box wth vncserver setup in it. Now, the problem is when I'm connected to the linux box via vnc session executing the command in terminal xrandr gives me the following:

Code:

$ xrandr
Xlib:  extension "RANDR" missing on display ":1.0".
RandR extension missing

plus the geometry the vnc uses is 1024x768 pixels instead of 1280x1024 that I had set in /etc/sysconfig/vncservers:

Code:

$ cat /etc/sysconfig/vncservers 
# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the lines below to start a VNC server on display :2
# as my 'myusername' (adjust this to your own).  You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.  
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted!  For a secure way of using VNC, see
# <URL:http://www.uk.research.att.com/archive/vnc/sshvnc.html>.

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

# Use "-nohttpd" to prevent web-based VNC clients connecting.

# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel.  See the "-via" option in the
# `man vncviewer' manual page.

# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"

VNCSERVERS="1:tusker"
VNCSERVERARGS[2]="-geometry 1280x1024 -depth 24"

I don't have any idea what to do next, since, xrandr is fine when I'm directly logged in to the linux box.
Anybody can walk me through this xrandr missing please...
Just let me know if you need more information with regards to this issue.

vncpasswd

vncpasswd(1)						     Virtual Network Computing						      vncpasswd(1)

NAME

       vncpasswd - change a VNC password

SYNOPSIS

       vncpasswd [passwd-file]

DESCRIPTION

       vncpasswd  allows  you  to set the password used to access VNC desktops.  It stores an obfuscated version of the password in the given file
       (default $HOME/.vnc/passwd).  The vncserver script runs vncpasswd the first time you start a VNC desktop, and invokes Xvnc with the  appro-
       priate -rfbauth option.	vncviewer can also be given a password file to use via the -passwd option.

       The  password  must be at least six characters long, and only the first eight characters are significant.  Note that the stored password is
       not encrypted securely - anyone who has access to this file can trivially find out the plaintext password, so vncpasswd always sets  appro-
       priate  permissions  (read and write only by the owner).  However, when accessing a VNC desktop a challenge-response mechanism is used over
       the wire making it hard for anyone to crack the password simply by snooping on the network.

FILES

       $HOME/.vnc/passwd
	      Default location of the VNC password file.
