Should I install original Nvidia drivers, for my Nvidia 8200. When i start installation, it asks me to close xserver. Only way to close it is use the command : "sudo service lightdm stop",because, desktop manager GDM, is not active in Ubuntu 12.02. The problem is that i do stop lightdm , this give to me a login bug also, when i run the command to stop service lightdm i get a black screen. As I do, to stop xserver, avoiding login bug?

It seems to me that for some reason you stay at the active virtual console 7 after stopping lightdm. Try switching to VC-1, login then stop lightdm. The magical accord is Ctrl-Alt-F1. –  Danatela Jul 18 '13 at 7:37
OK, this is not 'some reason', it is default behavior when you stop lightdm from X session active. So just try suggested solution. –  Danatela Jul 18 '13 at 7:46
