That seems like a good thing to do. Another thing you could do is post your grub.cfg. It seems a little odd you haven't. Also from previous discussion I think it's worth mentioning that Grub doesn't actually read /etc/default/grub, update-grub reads it to generate /boot/grub/grub.cfg. So only editing /etc/default/grub doesn't change Grub config in any way. If you're up for it, you could setup a serial terminal and send Grub output to serial and/or console. That way you might be able to boot and wouldn't have to switch video cards to try different configurations. But if you only have that one computer then I guess not.
