I think I've reproduced this same error, though the scenario is slightly different:
System Info - Lenovo thinkpad X200 notebook - Intel GM45 Express graphics - Ubuntu 12.04 32bit (x86-32). up-to-date as of June 2 / 2012 Steps to reproduce - set setting "when the lid is closed"="do nothing" in Power settings - set "Lock" to "On" in Brightness and Lock settings - check "Require my password when waking from suspend" in Brightness and Lock settings - close the lid - open the lid expected results: I see the log in dialog actual result: backlit but dark screen, mouse cursor still moves as normal, mouse cursor changes as I move it around the screen as if it is responding to diff't UI elements. Occasionally the display is different: instead of blank/black screen other windows are visible, such as the dock and the top panel... but when that happens I cannot interact with them. The issue is intermittent. Cannot be reproduced all the time.
