When i just close my laptop lid and reopen it, the screen becomes dark with only cursor appearing. I guess it is when the password prompt screen that when launched causes this because for few seconds i can use the laptop before the password prompt comes in. I reproduced this on Kubuntu 13.04 compiled from source and openSUSE rpm. Choosing normal Oxygen before sleeping avoid this issue. Reproducible: Always Steps to Reproduce: 1. Close laptop lid to make sleep 2. Reopen Actual Results: Dark screen with only cursor Expected Results: Prompt for password Kubuntu 13.04 and openSUSE. Require password to login : true
