The tool provided along with NVIDIA driver changes your resolution in /etc/X11/xorg.conf but not in monitors.xml as gnome’s “Monitors” tool does. As a consequence you need to edit /home/username/.config/monitors.xml manually:

<monitors version="1">
 <configuration>
 <clone>no</clone>
 <output name="default">
 <vendor>???</vendor>
 <product>0x0000</product>
 <serial>0x00000000</serial>
 <width>1920</width>
 <height>1080</height>
 <rate>0</rate>
 <x>0</x>
 <y>0</y>
 <rotation>normal</rotation>
 <reflect_x>no</reflect_x>
 <reflect_y>no</reflect_y>
 <primary>no</primary>
 </output>
 </configuration>
</monitors>

Julien Lavergne provided a fix which isn’t yet available in the Ubuntu main repository but you can download a fixed version of the package from his PPA: 0.1.2-6~ppa6. Checkout this doc from launchpad to add a PPA and its key to your Ubuntu repositories.

If as soon as you select the Widget settings the widget disappear it means that the Widget layer plugin is activated in your compiz fusion options. Inactivate this option in CompizConfig Settings Manager.
 
The goal of the widget layer is to have the widgets displayed on top of all your windows when pressing a special key – F9 is the default key.
