I was able to get the second display to work by using the package ARandR. When I bring up the NVIDIA X Server Settings it does not recognize any display as shown below.



I have been able to get my system to behave correctly by switching to the Intel card in my Laptop. It recognizes both displays. This problem comes up with many hits using Google and I have yet to find a workable solution. I would be interested to know what needs to be added to my xorg.conf file as one option. I am starting to wonder if the problem is in the NVIDIA driver when it has a second display. My impression is also that it does not correctly recognize my Laptop display when it is only connected. My system is:

ASUS R501VM, Core i7 3610QM, 16GB Ram
NVIDIA GeForce GT 630M 2GB

I suspect the problem is an Intel card vs. the nVidia. If the Intel card is active, nvidia-settings can't deal with it. If you have the option to disable the Intel video and run both monitors from the nvidia card then you might have an easier time. If you configure both cards, you'll have to use xorg.conf and tweak it until you get it right.

I think you'll need to add two Monitor Sections and add them to your Screen sections.

You can always just use xrandr if that gets you the results you want. Simple enough to add the xrandr command to xsettings.

I have finally returned to try and get my Nvidia card to work. I have the nvidia-331 files installed and my system still comes up with a black screen for login. I have found that if I enter my password, the system starts correctly with only one screen working. My second screen is not being driven. To solve this, I used arandr to detect and activate the second monitor. I was able to save a shell file from arandr and I execute this file when I boot to get the second screen working. I chose to execute the shell file on reboot, as I can connect my Laptop to different monitors which require their own xrandr settings. I find that System Settings > Display and Monitor shows no Primary monitor defined. I can define a primary monitor but it is not recorded as, when I return to this menu, it is still undefined.

I decided to look at the log file and I found that the nvidia license taints the kernel. The log file of interest is:

My NVIDIA X Server Settings still show no monitor and I am wondering if the above errors are the culprit. Am I barking up the wrong tree or does anyone have any idea on what the best solution is?

Sorry, that's not it. Here's mine:

I have tried connecting my Laptop to a Samsung Digital TV via the HDMI connection and in this case I get a visible login screen. The log file now has:

In this case I do not get a dual screen. It acts like one big screen even though System Settings > Display and Monitor shows two screens. I also do not get any sound from my Laptop on the TV with the HDMI connection. I am wondering if you are able to get sound on the device connected via the HDMI?
