I tried the DisplayPriority but it didn't resolve the issue. I'm thinking it's a ubuntu issue. I noticed the filemanager is attempting to load over and over again. Each time the cursor changes to a wait cursor and the desktop flashes. When the password box is displayed (black desktop) the screen is not flashing. Hopefully this will be addressed in alpha 3.
