[Bug 545572] Re: Upon resume, external monitor has signal but laptop screen does not

 

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  My Lenovo x200s is connected to an external monitor (Acer AL2016W).
  
  When I suspend by closing the lid on my laptop, I see the login screen
  on the monitor for second before it suspends.
  
  Then after I resume (by opening the lid) the login screen is there on
  the external monitor and after I log in the laptop screen is not showing
  anything. I think the laptop screen is disabled.
  
  When I open display properties it turns on the laptop screen.
