Re: Multihead from readme :)
The input sections of the second keyboard and mouse should also be correct (they should load the right devices). But further even when that works you can't use a single nvidia card for a multihead setup. An nvidia card can only work in twinview or 'cut in two pieces' when using seperate X screens. In case of seperate X screens both displays are in the same X session (so using a single Xserver). Using two displays at the same time from different Xservers is not possible unless you add a second videocard.
