Comment 0 for bug 1186961

seen on Thinkpad x220 with dock

1. Take a screenshot on your laptop while its undocked - see how it works
2. Suspend your laptop (by closing lid)
3. dock you laptop
4. resume your laptop
5. see how the login screen still uses the laptop resolution on external screen (not this bug)
6. take screenshot of a window using ctr+print key combie

Screenshot does not contain the window, but just black.
