[ubuntu] Purple/Black screen after installing 13.04 64bit

Here is my system:

Note the NVidia 770m + optimus

I have recently with much difficulty managed to install 13.04 64bit.

After setting these paremeters, I have finally managed to see where the boot up process has crashed. I will include some of the output that I managed to write down below:
=================={Bootloader options}==========================
acpi_osi=Linux
acpi_backlight=vendor
video=1920x1080@60
no splash

================={ approximate output}==================================

Given this information, is anybody able to help me make Ubuntu bootable/usable?

Thanks,
