Bug#768896: possible fix. NOT WORKING

[Daniel Lange]

The proposed fix from Adi doesn't work here.
Problem still exists with a freshly upgraded wheezy -> jessie Nvidia system.
No issues in wheezy. Same black/white stripes pattern as described by 
everybody else here.

gsettings set org.gnome.desktop.background picture-uri 
'file:///usr/share/backgrounds/gnome/FootFall.png'

as a really ugly workaround after each resume.
