I'm sure your are correct about that, so that eliminates that option.

I haven't actually tried to install Ubuntu yet. I have been holding off
and gathering info, hoping to improve my chances of success. However if
I do not disable efi and add nomodeset the live dvd ends at a black screen.

See above. I do remember seeing some screen corruption at one point but
it cleared up and I had a normal looking live dvd desktop. Probably not
the same situation but I just opened the display settings and it shows
1368 x 768(16:) with no other options in the Resolution dropdown.
