So it's a Dell SLI Gaming laptop.

Select an older kernel image in your grub menu, boot with the nomodeset option > find additional drivers... Reboot using the older kernel image (around 2.6.37... you said you had 10.10 on it before).
If that doesn't work, rename your xorg.conf > go to /etc/default/grub...
Uncomment the "GFXMODE=640x480" line in /etc/default/grub in this section
sudo cd /etc/default
sudo gedit grub
Edit it to this:
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
Then go to this line (same file):
Edit to this:
I would say to add a VGA Vesa modeset, to that line, such as vga=795... But since we have some kind of problem quesrying the nvidia chipset to find those modes,,, That's kind of hard to guess those, so
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
That "should" work.
I'm thinking that in previous versions of Ubuntu, the Video was not really "changed" until the Graphics Session started. It then used the settings in Xorg, the "drivers" and conf files to change that. The last 2 versions starting taking kernel modesets to "prep it" previous to the Graphics Session start. This current version of Ubuntu is now querying and trying to set the graphics from the grub level before the kernel even starts. At that level, those initial quesries are confused on your hardware, so we might have to prep the graphics manually.
Using the older kernel? Well that would prevent an invalid parameter or mode from locking up the graphs session by not passing it along to Xorg. Installing an older grub would do the same thing, by not passing on the newer parameters.. Problem with the 2 options in this paragraph, is that they are only a temporary workaround, until that bug was resolved..
