Second Display is not detected ubuntu 12.04 on Dell Precision 390 desktop

Question

I have a Dell Precision 390 desktop. I just did a clean install of Ubuntu 12.04, ran all of the updates (~150), and updated the NVIDIA drivers. Then I restarted. My second monitor was not working before or after any of the updates. I'm a huge beginner with Linux, so bear with me. Can anyone help with this?

Solution

I had a same problem on one computer.. after some time of trying to solve problem I decided to return to native driver and then everything works fine - Deactivate Nvidia driver and native driver will be activated, then go to monitor preferences and setup dual monitor. If you realy need 3D try with different conigurations.

If it worked, then stop working after updates, then this question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here.

If you are using the Nvidia driver, start Nvidia-settings in the dash and you will be able to activate the monitor by clicking on the second screen and selecting Twinview.

Twinview is useless for most of users including me... it is better to have 2D on two different screens than 3D on twinview...

@linomans: Is there a reason for that? I just enabled TwinView and it works perfectly fine.
