[Pkg-xfce-devel] Bug#785055: lightdm-gtk-greeter: white screen until I click a mouse button, with 2 screens

[Vincent Lefevre]

Package: lightdm-gtk-greeter
Version: 2.0.0-2
Severity: important
Tags: upstream
Forwarded: https://bugs.launchpad.net/ubuntu/+source/lightdm-gtk-greeter/+bug/1426664

After upgrading lightdm-gtk-greeter on my laptop, the screen was
entirely white. I was wondering why, while there was no such problem
on another machine, and after Googling, I've found:

  https://bugs.launchpad.net/ubuntu-mate/+bug/1426664

where it appears that this problem occurs when there are two screens,
which is the case with my laptop.

I also thought that lightdm-gtk-greeter wasn't working at all, until
again I read this bug report, where it is said one just needs to
click. So, there's a workaround, but the user may be blocked without
noticing it.
