My Dell D610 has got this issue after an upgrade to LL 2.4 from 2.2. I used to open lid and just press the esc button twice and I'd get the login. Now it black screens. Is there a way of going back a version? Meanwhile I fiddled round in power manager and using settings of on ac/hibernate and on battery/suspend I can press menu/logout/suspend and close lid. On opening it goes to login and I can log in no problem. This is with wall power permanently on. I never use the battery alone although there's one in with little charge holding ability.
