Andrew P. has proposed merging lp:~kalgasnik/lightdm-gtk-greeter/focus_fix into
lp:lightdm-gtk-greeter.
Requested reviews:
LightDM Gtk+ Greeter Development Team (lightdm-gtk-greeter-team)
For more details, see:
https://code.launchpad.net/~kalgasnik/lightdm-gtk-greeter/focus_fix/+merge/199652
Switching focus between greeter windows is not handled correctly .
Open/close shutdown dialog to reproduce it - only window under cursor can have
focus (and catch keys press, so you can close this dialog using "escape" key
only when dialog is under cursor).
The solution for this problem is taken (copy/paste) from unity-greeter.
