lspci list all pci devices.. what I need is your video card name.. ATI, NVidia.. Version etc.. in lspci you'll find the vga info.. The "start from recovery mode" that i said before, was only for reach the terminal..

Have you recently installed the proprietary ATI drivers in your system? What happen before the problem were raised? have you installed updates? Have u try to install some video drivers?
