I tried again, and I have made a copy of xorg.conf before installing nvidia drivers. Because it is when I install nvidia drivers that there is no more graphic interface after the restart of Ubuntu. Then I modified xorg.conf and configured those two devices, SLI option, which device on the screen, but without succeed.
So I replace the old xorg.conf that don't specify to use nvidia drivers (and I restarted computer), but I still have the same problem... no xorg. So is there any other conf file like xorg.conf that could skip xorg?
