Great - could you also attach the file: "~/.xsession-errors" after the
second monitor fails to wake up?

That would be helpful as well.
Thanks

  I just upgraded my media center to Intrepid via a clean install, and
  there's a strange problem with powering down the displays.
  
  Hardware:
  Foxconn 6150BK8MC-KRSHN2 Socket 939 Motherboard (onboard video, one VGA and one DVI)
  Samsung LNT3253HX 32" LCD HDTV
  
  I'm using the nvidia-glx-177 restricted drivers, and have my screens
  setup with the attached xorg.conf (generated by nvidia-settings).
  
  The HDTV is plugged into the DVI port and set up as the second display
  (within a single X server). There is a smaller LCD plugged into the VGA
  port and set up as the primary display.
  
  After 5 minutes of inactivity, both screens go into powersave mode as
  expected. When I press a key or wiggle the mouse to wake it up, the
  small LCD (primary screen) wakes up, but the HDTV stays dark and
  continues to say "No signal."
  
  If I restart X with control-alt-backspace, the HDTV immediately wakes up
  and works fine until the system turns it off.
  
  I'm not sure if this is an issue with the nvidia driver or with the X
  server itself, so I'm not able to assign this to a specific package. I
  was unable to find a similar bug reported elsewhere.
  
  For what it's worth, I have a similar setup on another computer (same
  driver, similar xorg), but with a PCI-E video card and two DVI monitors
  and that does not exhibit this problem.
