Re: Graphics Resolution- Upgrade /Blank Screen after reboot
With 10.04 you will not have Unity or the test file, so that error message is expected.
I have little detailed knowledge of Intel video cards and I gather the [8086:2a02] GM965 primary  running the i915 driver is normal. The [8086:2a03] as secondary  is something I have not come across before and I have no idea if it is normal for lspci to show it without drivers, or if it should run in parallel like SLI.
Have you checked in Bios to see if there is an option to choose or omit one or other of the GPU's?
Perhaps lshw will be more informative if you can Post its output.
Please also repond to my other query:
sudo lshw -C display
If you are Posting a lot of text, please use some line spacers to break it up into a more readable form.
Please also confirm if it will run OK from a LiveCd/Usb, or, if not, how far it gets, and what errors does it show.?
