Bug Description

With the lightdm 1.21.5-0ubuntu1 I sometimes find I am shunted back to login screen after entering password.

Appears to depend on how fast I enter the password the first time.

Unable to ubuntu-bug - got 3rd party warning, not sure why.

Finding this to not be an issue when nvidia drivers are installed.

As an observation, it is noticeably slower to show the login screen using nvidia opposed to nouveau.

Which looks like another race condition - I think LightDM has decided that there's nothing running on that seat for some reason and started another greeter.

Face the same issue with lightdm 1.18.3 Seems like a regression to me.
