Why can't I get the right screen resolution in Ubuntu?

[idata]

Hi

My screen resolution in windows and previous version of ubuntu (9.04) was 1152 x 864.

But in Ubuntu 10.04 it gives me an option of 1024 x 786 and 1360 x 786, how can I change it to 1152 x 864 ?

Is there any way I can change my screen resolution to 1152 x 864 ?

Thanks.

Edit : I am sorry I forgot to mention my graphic card details.

It's http://www.intel.com/p/en_US/support/highlights/graphics/intel945g Intel(R) 82945G Express Chipset Family.

Edit 1 : This is what I have tried according to http://superuser.com/users/41521/matan-eldan Matan Eldan.

searock@searock-desktop:~$ cvt 1152 864

1152x864 59.96 Hz (CVT 1.00M3) hsync: 53.78 kHz; pclk: 81.75 MHz Modeline "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync

searock@searock-desktop:~$ xrandr --newmode "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync

searock@searock-desktop:~$ xrandr --addmode S-video 1152x864

xrandr: cannot find output "S-video"

Then I tried executing xrandr command and it displays the resolution but I think I can't add it to the output.

searock@searock-desktop:~$ xrandr
