Week 39 - Nvidia machine not detecting 2nd monitor

[Nice Testhouse]

Ubuntu 12.04 Precise with ppa:unity-team/sru

Issue: Nvidia machine not detecting 2nd monitor.

Additional info:- Did a fresh install of 12.04 and ran the updates, installed nvidia-current driver.
In Nvidia X server settings, both monitors were shown as diabled. I set both to twin view and restarted the machine. This did not help.
Now opening Nvidia X server settings shows this message "You do not appear to be using the Nvidia X driver. Please edit your X configuration file (just run 'nvidia-xconfig as root), and restart the X server".

O/P of command jockey-text -l:

xorg:nvidia_173 - NVIDIA accelerated graphics driver (Proprietary, Enabled, In use)
xorg:nvidia_173_updates - NVIDIA accelerated graphics driver (post-release updates) (Proprietary, Disabled, Not in use)
xorg:nvidia_current - NVIDIA accelerated graphics driver (Proprietary, Disabled, Not in use)
xorg:nvidia_current_updates - NVIDIA accelerated graphics driver (post-release updates) (Proprietary, Disabled, Not in use)
