I am facing the same issue with Intel 915. When I leave the computer for some time, and come back after half an hour or so. I find that the screen remains black with the mouse pointer visible. Seems like the password window appears as well, but does not display.
This does not happen when lock for a minute or two, but after long periods. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/781402 Title: Ubuntu 11.04 / Unity freezing when screen is 'woken up' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/781402/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
