I get black tty screens when I hit Ctrl+Alt+F1. I already read all other similar questions but I can't seem to find a suitable solution.
Here is my setup.
I have a fairly new laptop (Jan 2013, Asus G55VW). It runs with EFI, came with windows 8. I wiped out windows 8 and installed Ubuntu Precise LTS. It has a Nvidia GTX 660M and I am using the 310.14 drivers.
I tried fiddling with the kernel boot options (nomodeset, agp=off, video=efifb, setting some obscure resolutions and mtrr options, etc...) as suggested by other threads. I tried the FRAMEBUFFER=y trick too... I tried booting without splash, or booting in safe mode, etc. nothing worked.
One funny thing though, when removing the "quiet splash" from the kernel boot options, after grub, the screen remains purple (default grub color) and I see black lines appearing one by one on the left, I guess these are the kernel messages that are not being diplayed properly.
In grub, I ran the
videoinfo command and this is what it gave me:
List of supported video modes: Adapter 'Cirrus CLGD 5446 PCI Video Driver': No info available Adapter 'Bochs PCI Video Driver': No info available Adapter 'EFI GOP driver': 0x000 1920 x 1080 x 32 Direct ... ...
(typed it myself from a picture I took, so I shortened it a bit)

In particular, note the following lines:

what should I do?
