Comment 8 for bug 1261818

Additional info: if I do a software update which results in me having to restart Ubuntu after the update, the bug is temporarily fixed.

What happens is that, following the restart, I can now type straight into the password field on the unity-greeter screen without having to use the mouse workaround described in Comment #6.

However, this 'fix' only happens once: the next time I have to log in, I can only type into the password field using my mouse click workaround.

This temporary fix has occurred more than once, so it's not just random. What is it about a Ubuntu software update that causes this bug in unity-greeter to be temporarily fixed?
