I have follwing hardware configuration of my PC

Intel DG31PR Motherboard 32bit.
This mother board has onboard Intel Graphics Card 
description: VGA compatible controller

Processor:Intel® Core™2 CPU E7500 @ 2.93GHz × 2 Display Monitor: HANNSpree HF225 22"Display

I have install Ubuntu Linux Server 12.04 on my above configuration

The OS Details are as follows

Release 12.04 (precise) 32-bit
Kernel Linux 3.2.0-29-generic-pae
GNOME 3.4.2

As I am new to Linux. This is my first time to work on linux because of a project requirement. I tried to change the resolution of my desktop by going to Applications>System Tools> System Settings>Display But there I got only two options for resolutions i.e 1024 X 768(default selected) 800 X 600

As my graphics card and my monitor supports higher resolutions when I was running Windows 7 on above configuration.

But in this I am not getting the Higher Resolution than 1024 X 768. It is tadious to work with this lower resolution on big display.

So I want to ask the experts that What it the problem with my machine or with the OS.

What should I do to increase the resolution.

Please give me the solution in details as I do not have much information about Linux.

Please guide me experts! Thank You!

If you type xrandr on a console it will show you the resolutions that your monitor supports, you can change it like xrandr -s 1024x768 with a resolution that is listed there. You may need to update your kernel if it doesn't have the drivers for your video card. But in all likelihood it should have them built in unless you've compiled it manually? –  nikhil Feb 8 '13 at 10:47
