Comment 6 for bug 379008

I switched the lid close event to blank screen for both on AC/on battery (via Power Management Preferences).

Now, when I close the lid, the display switches over to external but does not blank the screen. Upon reopening the display switches back to internal but an error notification appears (something about virtual size, disappears too fast to read).

I don't know if this auto-switching to external screen on lid close is expected or not. I think it should not happen if lid close is associated with suspend, because it makes no sense to switch the screen if the computer is going to sleep anyway.
