GTS450 + HD4000 Ubuntu 12.10

**scabs** · April 7th, 2013

Hi All,

I wonder if someone could assist with this issue i am having

I am trying to use both the internal HD4000 and external GTS450 at the same time with me install. In the BIOS if i choose to use the internal during boot, i only see my one monitor ( the other remains black ). This happens the same as when changing the BIOS to use the external, the monitor connected to the internal is black.

Is there any way to use both at the same time?
My untimate goal is to have three monitors hooked up.

Thanks in advance for any assistance.

Edit: adding further info

Okay after adding the above to xorg.conf i now get the two monitors attached to the nvidia card displaying correctly and the monitor connected to the intel card is plain white with nothing else showing. I can move my mouse cursor over to this monitor, but i can't move it back and it gets stuck there.

Any help would be greatly appreciated.

Thanks.
