915Resolution: Intel Video BIOS Hack
Steve Tomljenovic [stomljen at yahoo dot com]
915resolution is a tool to modify the video BIOS of the 800 and 900 series Intel graphics chipsets. This includes the 845G, 855G, and 865G chipsets, as well as 915G, 915GM, and 945G chipsets. This modification is neccessary to allow the display of certain graphics resolutions for an Xorg or XFree86 graphics server.
915resolution’s modifications of the BIOS are transient. There is no risk of permanent modification of the BIOS. This also means that 915resolution must be run every time the computer boots inorder for it’s changes to take effect.

debian package: debian package
Download from within Ubuntu to directory or desktop
3. Install debian package
Within terminal:
dpkg -i ‘directory’915resolution_0.4.6-1_i386.deb
4. Display available resolutions
Display the available resolutions :
# 915resolution -l
overwrite the 3c resolution (not used)
915resolution 3c 1920 1200 24
Display the available resolutions :
5. Write script
Note that you need to set the video BIOS with 915resolution before you start up the X server. You don’t need to set them all. Just pick an unused mode with the right number of bits per pixel. Also, the setting is not permanent. You need to set the VBIOS every time you start the machine.

After some playing around, I found the best way to run my startup script was to add it at the end of:
/etc/init.d/rcS.sh
The other menthods mentioned did not work for me.
I have a Dell Inspiron 700m that need a 1280 x 800 screen resolution. I was able to get it to work with a great tool called 855resolution that need to be executed at startup.
Put 915resolution 3c 1920 1200 24 at the end of /etc/init.d/rcS.sh !!!!!!! (edit file as root user)
DOES NOT SEEM TO WORK:
Instructions on Ubuntu: 915resolution
1.Download 915resolution
2.run “915resolution -l” as root
3.Pickup an unused resolution (’3c’ for me)
4.run “915resolution 3c 1400 1050 32″ as root
5.Edit /etc/X11/xorg.conf to add:
Option “ForceBIOS” “1920×1440=1400×1050″
As a result, the /etc/X11/xorg.conf looks like:
