As I understand it, in Ubuntu 11.04 setting the AutoHide setting on Compiz Config - Unity (see here) not only hid the launcher but prevented the launcher from influencing window placement.

However, since updating to Ubuntu 11.10 when I open a new window it gets indented the space of the launcher. I just want new windows to open flush left. This is annoying, because I like to have two windows on my large screen, one taking up the left half of the screen and the other taking up the right half of the screen. Indenting causes them to overlap.

How can I stop Ubuntu 11.10 thinking that the launcher takes up desktop space when placing windows?

The following screen shot shows what I'm talking about. I've just opened chromium and the window is indented by the width of the launcher.
