Changing the xorg.conf in order to use HDMI

Asked by Tomas Nilsson

I have a Dell XPS 15z laptop with Ubuntu 11.10 and would like to be able to use an external monitor via HDMI. I understand that Optimus is the reason why it doesn't work.

Until there is a better solution I would be happy if I could use only the external monitor and not the laptop screen. According to https://wiki.ubuntu.com/HardwareSupport/Machines/Laptops/Dell/XPS/15z this is possible:

"The HDMI is physically connected to the nVidia card -- by manually changing the xorg.conf, it is possible to start X on the nVidia card only, getting the HDMI video (at the cost of inactive main laptop screen and the Mini Displayport output). "

What should I add in my xorg.conf file in /etc/X11/ in order to use the external monitor via HDMI?

You should try to ask these guys here: https://github.com/Bumblebee-Project/Bumblebee/issues

I am pretty sure someone managed to use the HDMI output by heavly hacking an older version of Bumblebee. But, basically, to have the HDMI output, you need to make the right calls and they also depends on how the hardware is wired and stuff.. ( this information is basically on the hands of Nvidia ).

On the FAQ of Bumblebee, it is said that work is in progress to make the HDMI port work. =}
