** Description changed: This seems like a recent regression on Oneiric (or perhaps I haven't noticed it before): On resume from suspend, the contents of the desktop are often briefly visible before being hidden behind the lock screen. This is a security problem if there happens to be sensitive information on the screen. + + + =====Analysis from mdeslaur===== + This is likely what happens: + + 1- Something grabs mouse: ie: virtual machine window, or GTK menu in an application or an indicator + 2- Screensaver attempts to start, but cannot get exclusive lock on mouse + 3- DPMS turns monitor black + 4- User moves mouse, which turns the screen back on + 5- Mouse movement causes mouse to get ungrabbed by vm window or gtk menu + 6- Screensaver can now grab mouse, and starts + + This is all related to the fact that X does not have an API that will + let the screensaver tell an application to release mouse and keyboard + grabs.
