I had just disconnected the projector from the external monitor connector on my Dell 640m, and was taking notes in a kmail composer window, when all of a sudden the screen went black and I was returned to the login screen. Good thing kmail keeps what you were doing. What had essentially happened, I think, is that the screen resolution changed from the 1024x768 it was using while the projector was connected to the native widescreen resolution; this apparently triggered a logout or similar. -- Lamar Owen www.pari.edu
