unity-greeter disappears after 10 seconds following boot

[John Mackoy]

When booting, the unit-greeter will appear as I expect it to, but after approximately 10 seconds the greeter wallpaper and the login prompt disappear. I can still see the mouse pointer (and can move it) but nothing else is visible.

I've learned that I can still login to the system by typing my password in blind, however; this is less than optimal as if an errant click of the mouse is made the focus will be taken off of the password field. This means that I cannot login without a hard reboot.

Thank you for your bug report, does it do at every login? Is your screen still on? Do you use a multimonitor config?
