Subject: [PATCH] loginDialog: Reset auth prompt on vt switch before fade in
At the moment, if a user switches to the login screen vt,
the login screen fades in whatever was on screen prior, and
then does a reset.
It makes more sense to reset first, so we fade in what the
user is going to interact with instead of what they interacted
with before.
