Windows 7 dual physical screens remain blank after remote desktop

Description: If you running Win7 Enterprise version on a Dell Optiplex 755 ,780 or 790  with an ATI Radeon HD2400Pro PCIe card and the ATI 9.11 Catalyst Drivers/Control Center, you might have encountered this issue.
Error: "No Such Error"

Resolution:
There is no such solution available so far but there are couple of workarounds that might work out:

  • Unplugged the DVI cables from  monitors, swapped the cables over and plugged them back in (this is because monitor #1 was on the right and not set as primary. 
  • Try to update the Graphics driver.
  • At console session... Keep in mind, you will not see any change in the main screen until after you have completed the steps.

    1)  Hit CTR-ALT-DELETE
    2)  Type your password
    4)  Hit ENTER twice.

    This actually will work.
  • Log in another computer and check the Windows Desktop Manager service, if it is stopped, try starting and check if it works.

In Windows 7, the Java Control Panel icon may be damaged / corrupted. Attempting to launch the icon results in "Explorer.exe : Application not found". Note the generic icon: When working properly, the circled icon should look like this: This problem appears to be an artifact from previous JRE installations and Sun's installation routines were flawed. Re-installing JRE (the Java Runtime Environment) does not resolve the problem. Immediate workaround: If needed, the Java Control Panel can be manually launched using this location: C:\Program Files (x86)\Java\JRE6\bin\Javacpl.exe As a side note, when launching, other-mouse-click the .exe and choose "Run as Administrator".  Running as Administrator resolves a bug where changes in the Control Panel (especially Auto-update changes) do not stic
