Does Ubuntu use Xorg? Search for the xorg.conf file and in there, under your graphics settings, you can remove the resolutions you don't want and just add the one you do want. That way it won't have the option to use the lower resolution. Just be sure, before you do that, that you are comfortable using a rescue CD to restore the original file in case it causes Ubuntu to stop loading. So backup that file first! I have done this and it does work but I have also experienced problems with the xorg.conf file and needed to take the recovery steps I mentioned.

Run sudo dpkg-reconfigure xserver-xorg. Accept all of the default values (just keep hitting enter, use the tab key to select the OK buttons) until you hit the screen resolutions (they're at the very end of the setup). Select which ones you want.

Available screen resolutions are determined by the display driver. The driver will ignore resolutions its not programed for. When you run "sudo dpkg-reconfigure xserver-xorg" it will change the display driver to an open source version. For example, if you have an Nvidia card or mobo chip set "nv" will be used as the driver. That driver doesn't do direct rendering. Assuming you had perviously installed the proprietary Nvidia driver called "nvidia" you'll need to edit /etc/X11/xorg.conf to change "nv" back to "nvidia".

I am hesitant in piggy-backing to this post, but I am attempting the same thing. I have the 915GM video card, and have ran the 915resolution app to change one of my modes. I am in the process of running the
Code:
sudo dpkg-reconfigure xserver-xorg
and realize, if I change the xorg.conf file afterwords, should I select the I915 or I810, or what changes do I need to make.

My apology to the original poster for adding to this thread. Seemed like a 'fresh' thread.

Back up your /etc/X11/xorg.conf file. Then, just play around with the dpkg-reconfigure and select either the 810 or the 915. Something goes wrong, just restore the xorg.conf file and you are back to square one.

If you've done a proprietary video driver install, before running "sudo dpkg-reconfigure xserver-xorg" record the driver name from xorg.conf. That will be the driver name you restore in xorg.conf.

1024X768 is the most the "vesa" video driver will do. Open a terminal window and enter "lspci |grep VGA" and we'll be able to see what chip set is in your video card. A different driver may be available that will allow higher resolutions. "vesa" is the generic driver that will work with all video chip sets.

Best I can determine, for the 945G chip set, the driver you want is "i810". First make a backup of /etc/X11/xorg.conf, next find "vesa" in xorg.conf and change it to "i810". You'll need to restart X which worst case can be done with a restart/reboot. The i810 driver should already be on your hard disk so no install should be necessary. If you have problems you can revert to the old xorg.conf backup.
