Note that later Ubuntu versions start the graphics screen quite early to get their "splash screen" up. If X can't properly control the screen, no surprise the Ubuntu splash screen doesn't work, either. I'm pretty sure there is a grub option at boot time that just disables the graphics entirely. That would at least get the machine booted and the keyboard-screen system working. You can then try stuff a lot more easily with the startx command, and possibly needing to do ctrl-alt-backspace to crash it. If X is running normally but you just can't see the display, then ctrl-alt-F1 should drop into a TTY screen with basic VGA-only access, without killing X. But, I'm wondering if this is actually a MONITOR problem. X reads the screen's capabilities through the DDC pins, but some monitors produce info that confuses some drivers, or just the timing of the interchange causes one or the other to malfunction. With an older nVidia driver, it would scramble my ViewSonic LCD screen, and I had to pull the plug and power it back on (powering-off by the panel button did not work) to get a usable screen. Later drivers have fixed this. So, I would try the problem system with some other monitors to see if that sheds any light.
