Comment 2 for bug 1385441

Same problem for me.

Lock screen works fine, but if I try to unlock after few minutes, I got the password prompt again.
I got access to my Ubuntu laptop (14.10) only forcing a power cycle, pressing the power button for 5 seconds.

Local user for me as well and it's probably hard to troubleshoot seen I cannot do anything but trying login.
FYI: If I put the wrong password, it recognizes the password is wrong.

If you need any further info from my side, please let me know.

Thanks

GF
