Bug#479593: gksudo's dimming feature does not work as intended with nVidia TwinView configured.

[Trygve Vea]

Package: gksu
Version: 2.0.0-5

gksudo's dimming feature does not work as intended with nVidia TwinView
configured. It only dims one monitor, and in my case it is not the monitor with
the gksudo-window.

It is very easy to reproduce; simply run

 # gksudo echo lol

In case it will be helpful to reproduce the error, I have included my xorg.conf
below. lspci says my graphics card is the following:
