Using onboard and pci-e graphics card at the same time
- by Endle
Hello wonderful people.
I know there are several other posts with similar questions. I also know how to use Google. I also have read up on posts discussing bumblebee, crossfire, ati catylist and many other interesting topics.
I would just like someone to give me advice on how to use the onboard and pci-e graphics at the same time.
I know the computer is capable of doing this. It works in Windows. I can use the VGA and DVI onboard port and the HDMI port of the add on card all at the same time. Works great in Windows 7,
In Ubuntu, it seems only one or the other will work. I can use any combination of two displays on either adapter:
VGA and HDMI..HDMI and DVI..so forth and so on.
I have started experimenting with xorg.conf files, but have not been able to get any of them to work. Here is my last attempt at writing an xorg.conf file:
