So (I guess) it has a different graphic card. From your forum post I see that that nouveau driver for NVidia cards doesn't know your graphic card. You can try to disable the framebuffer support on boot at all. Replace video=efifb with vga=normal in the grub.cfg. I have updated the article as well. Also in my case the nvidia driver doesn't work in X11. I added Driver "fbdev" into the Device section of /etc/X11/xorg.conf. Could be that in your case this also doesn't work. Try vesa or vga in that case. Maybe you should try a more recent version of Ubuntu, if all of this fails as well. Christian Hi Tim,
