I am experiencing nearly the same issue with my Dell Latitude E6510 w/ Nvidia NVS 3100M under Windows 7 x64. It's driving me nuts, makes using my docked laptop a huge PITA.

Here is a description of what I'm seeing:

Monitors go into power saving mode (according to "Turn off the display" setting in Windows power management).
I move the mouse or tap the keyboard to turn the displays back on.
One of the two monitors attached to my docking station via DVI as well as my DisplayLink monitor turn back on.
The 2nd of the two monitors attached to my docking station via DVI doesn't turn back on (and LED indicates it is still in power saving mode)
In this state I can move the mouse cursor around the two monitors that are on but can not click anything.
- If I hit CTRL+ALT+DELETE the monitor still in power saving mode will turn on and display the appropriate Windows menu.
  - If I choose Cancel from the menu I am returned to all black screens with a mouse cursor.
    - I have left the computer in this state for some time and the graphics never seem to return.
  - If I choose Lock Computer from the menu I am returned to the login screen and can log on again which produces all black screens with a mouse cursor.
    - Some times after a minute or so the graphics and mouse seem to return.
- If I unplug the DisplayLink from the docking station's USB port the two physically connected displays both turn on and the mouse works.

I would be happy to provide logs or help with testing if it might lead to this issue being resolved.
