RedHat Screen is shifter to right

Hi Team
I have installed RedHat 6.3 Server on my Dell laptop
While Installation I have seen that my Screen is shifter to right on the desktop.
Right now my screen resolution is set to 1366x768.
I am not able to see the whole screen.

Take a look on this screen
please help

Hi,
How many RPM's you have installed ?
Try
yum groupinstall "Desktop" "Desktop Platform" "X window system"

I also had issue related to display in my Lenovo T430 with RHEL/CentOS 6.0 and 6.3

It got solved after installation of above group and kernel upgrade to ver. 2.6.32-279.19.1.el6.x86_64

Thanks Priy

Can you please guide me how can I upgrade the Kernel ?

Try with yum upgrade kernel-*

Is display proper now ?
