There's an issue with an Alpha/Beta Release of Ubuntu, what should I do?
I am running 12.04 with two users and am hoping I am just over looking something. When one user account idles and locks I am unable switch users. Is there a way for another user to log in once the system locks, or must the first user unlock the computer? I believe in at least some other distros I get an option on the lock screen to log in as a different user - but that option is missing. Any suggestions about anything i'm overlooking here?
