LightDM has nothing to do with unlocking the screen. I'm moving this bug to gnome-screensaver.
** Package changed: lightdm (Ubuntu) => gnome-screensaver (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/1062988 Title: blank windows Status in “gnome-screensaver” package in Ubuntu: New Bug description: i cannot figure out how to repeat this bug or even if it is a bug with lightdm, but every now and then when i wake up the screen (after it has been locked) i will see either a blank black screen or a blank screen with my desktop background image. the dialog box for unlocking the screen (where you enter your password) is there but cannot be seen. i can tell it is there because when i move the mouse in certain areas the cursor will change when it is in the 'text input' area. if i type my password and unlock the screen, all my windows remain blank, but again they are there because i can see the mouse cursor changing. the only workaround i've found so far is to switch to a console and restart lightdm.
