Comment 129 for bug 1311316

I had a new development.. Maybe I should report as a new bug? In case this helps anyone as a workaround or to fix the bug I thought I would post here:

I had the lock screen complain of the wrong password. I sure it was the right one as I tried many times and eventually opened a virtual terminal where the password worked (tried several times again in the lockscreen to be sure) BUT instead of using the unity or compiz trick as usual I found this process with ps -ef:

/usr/lib/unity/unity-panel-service --lockscreen-mode

and killed it, then the lock screen would take the password. This might be something for you to try I guess as as a workaround next time.. At least when I restarted the old way, the desktop, that is the panel, didn't quite work afterwards (at least the time disappears from the panel), and I would restart after getting in to be on the safe side. I might do that now also, but at least I do not seem to have any problems.

[This may not stricly be the same bug, but I guess the bug is in the same program and I would guess both this and the bug in the subject have the same root cause - memory at some point running out and making trouble afterwards.]
