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

 

Public bug reported:

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.
