I am also experiencing this but I never use suspend. I have had this problem with both lock on and off in Brightness settings. I am also on intel.
I hope this helps others. I have found a way to restore my session to save any open programs or just to close session cleanly. Once the problem happens I go to a tty(Crtl+Alt+F1), log in and kill compiz and compiz-decorator. Then I run metacity, return to X(Crtl+Alt+F7) and start closing programs. I then opened a terminal (Crlt+Alt+T) and launch gnome-panel which gives me a menu to log out. I do not know if metacity and gnome-panel ship stock or you have to install them. I never installed gnome 3 but it appears as a session option on my login screen. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: Resume from suspend leaves me with black screen or a screen of the desktop before it suspended (though the mouse still moves/changes cursor) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/966744/+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
