Bug#511607: only one screen is shaded during password dialog

[Armin Fuerst]

Package: gksu
Version: 2.0.0-6

I have a multihead environment with nvidia-glx and xinerama:

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen  0       "Screen2"
        Screen  1       "Screen1" LeftOf "Screen2"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
        Option          "xinerama"      "on"
EndSection

When I start a gksu-application (like root terminal),
the right screen is shaded and the left one remains
bright. The password dialog appears on the left screen.
Additionally (I think it's the same reason, that's why
I don't file an extra bug) the root terminal appears on
the left screen below an existing window and I have to
switch to it manually.
