I have a triple-screen setup on an ATI card. I have the same issue above, but I also have another...
Sometimes when I come to my computer in the morning for work, one screen will not have the input field, but two others will. If I mis-type my password in one of the working screens, the input field then disappears. If I type it incorrectly in the other window, the input field disappears on that one as well. Then I'm back to the issue in this bug. But if I do type it correctly on either of the working monitors, then sometimes I'll get another lock screen, and sometimes I'll get my desktop.
Additionally, if I do end up in a spot where I have visible fields, if I restart lightdm and then login, then I get the lock screen again after logging in and have to enter my password again.
The Unity Lockscreen has been a huge nightmare for me...
Let me add a small twist to this...
