Dual Monitors on card and integrated


I know this issue is all over the internet already. But I haven't been able to find a solution. They are all trying to do dual monitors on one card.

I have my main monitor on an nVidia graphics card. I also have a second monitor plugged into my onboard VGA. But...Ubuntu is not seeing the second monitor. I checked the CMOS, and the integrated video is enabled. From here, I'm lost. Thanks in advance.

That sounds unlikely. In my experience, the integrated video rarely can be enabled without having the BIOS treat it as the primary video.

There is info in the file /var/log/Xorg.0.log that can tell you whether the integrated video is really enabled. It is hard to interpret if you haven't seen a lot of prior examples, so attaching the whole file to your next post is probably best.

In my own experience, I've only gotten monitors on separate cards to work by manually editing /etc/X11/xorg.conf

To do that, I always configure the BIOS so the add in video is primary, then get Linux (usually on a liveCD) to configure an xorg.conf for just the plug in video and I save that file away. Then I configure the BIOS so the integrated video is primary and get Linux to configure an xorg.conf for that at save that file as well. Then (with integrated video still primary) I edit the xorg.conf using info from the two saved files to make it use both interfaces at once.

So what your saying is, make a xorg.conf with one having the primary on the card, and the another having the primary on the onboard video? Then take those two files and manually put them together. Sounds like it would work, but I don't know much about editing that file. Could I just post the files on here, and have you edit them together?
