 Launch VLC with no interface, fullscreen, without OnScreenDisplay and cropped (left+top+right+bottom)

+==== Ubuntu bugs and other things ====
+=== White screen on second, third and fourth monitor ===
+Especially with multiple sessions of Xwindow and Xinerama **disabled**.\\
+BUG: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/885989 \\
+Nautilus is buggy. Replaced with Thunar.
+:!: Removing Nautilus from a clean Ubuntu will remove gnome-session and break the desktop. You don't want that. To keep a working gnome-session, I added the gnome3 ppa before removing nautilus. Which actually updated gnome-session in the process.
+<code=bash>sudo add-apt-repository ppa:gnome3-team/gnome3</code>
+And to get something like DISPLAY:=0.1 in the command line, you need to bee in Unity2D. Geez.
+=== Cropping source videos ===
+Since Noemie has done some editing to the videos. She has brought letterboxed videos to display. And since we wanted the image to be fullscreen. I cropped the video using FFMpeg:
+<code=bash>ffmpeg -i input.dvd -vf "cropdetect=24:16:0" dummy.mpeg
+</code>
+detects where the cropping should happend. I could make calculations myself, but it was more fun to have it done by FFMpeg.
+<code=bash>ffmpeg -i input.dvd -vf "crop=720:432:0:72" -sameq -an cropped.dvd</code>
+Crops the video while keeping the quality the same, though removing the unecessary audio.
