I just installed 12.04.1 on an HP Pavilion dv6-2106ea. I have a second monitor plugged in the VGA port which was detected during the install (and used as a duplicate display). Now the install is complete it is not being detected.

According to System Settings | System | Details | Graphics I have an "Unknown" driver, but System Settings | Hardware | Additional Drivers says I have NVIDIA accelerated graphics driver (currently the Recommended release, but the other has the same effect).

This may be a duplicate of the unanswered Unable to use second monitor

Any help would be appreciated.

Is your graphics card actually an nVidia card? If so, try updating the nVidia drivers. – bdares Sep 4 '12 at 1:51
To check graphics card, try "lspci" without the quotation marks in a terminal window and check for yourself the information about your graphics card and add it as an edit to your post. – Oyibo Sep 26 '12 at 21:37

I had similar issue on my Ubuntu 12.04 setup. In my case the problem was with the X Windows setup. I had to start Dash Home → NVidia Xserver Settings → X Server Display Configuration.

The second monitor was Disabled, so I have to first enable it and the select configuration TwinView. You do need administrator privileges to save the new X Configuration to file, but it will give clue whether your problem is with your drivers or X Windows setup.
