xrandr

I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768       61.0* 
   800x600        61.0

1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it.

1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer:

CPU: Intel atom D2500 1.86GHz
Chipset: Intel 945GSE+ICH7M
LCD: 14" TFT 16:9
Resolution ratio: 1280*800
Video Card: Intel integrated GMA950

Does anyone know how to fix this?
