[Bug 71030] Lock Screen blanks screen instead of showing screensaver (on external monitor)

[Vikas BN]

Public bug reported:

Binary package hint: gnome-screensaver

Hi,

    When I choose either "Lock Screen" or the "Activate Screensaver" options,
   the screen blanks and remains that way. It doesn't show the screensaver.

   Also note, when i choose "fullscreen preview"  to select a screensaver, it works
   perfectly well.

   Also, this happens when I connect an external monitor and works fine on my 
  laptop screen.
  
   Details:
     Ubuntu edgy (upgraded from Dapper)
     Dell Latitude D610 
       Laptop screen resolution - 1024x768
       External Monitor (Dell 1905FP) - 1280x1024
       Video card - ATI mobility M22 (ATI Open Source drivers with DRI enabled)
