Hi all,

I have a clean install of Ubuntu 13.10 x64 on my Dell Inspiron 3537. Everything is working pretty well except the screen locking. Upon locking the screen (which in turn makes the screen black), if I attempt to unlock the machine, the screen will come back on but no credentials box will appear. I can still type in my credentials blind and unlock the screen, it's almost as if the credentials box is invisible. Has anyone else faced this problem?
