Hi,

I am looking for people who tried (or can try) the following setup with a
dualhead VGA card (like Matrox 450/550, Radeon VE and others) or with 2
VGA cards:

I would like to be able to run two completely independant X sessions for 2
users on the same computer. One would use the normal PS/2 keyboard and
mouse while the second user would use a USB mouse and keyboard.

With all my experiments I was only able to use different modes of cloning
or Xinerama or multiscreen for the same session. Also using more than one
keyboard/mouse for one session is possible (with the SendCoreEvents
options).

However, I was not able to define two Layouts (one for each set of
screen/keyboard/mouse) that would give independant displays (:0 and :1 for
example). The X server (XFree86 4.2.0) always just takes the first Layout
section and ignores the others.

Furthermore, on my Matrox G450, if I try to start X on the secondary
display only, it just doesn't work. X complains about a missing definition
for Screen 0 (the secondary display is Screen 1).

So, did anybody make such a setup or wants to do it or is researching the
same or has any ideas ? I would like to know wether it works before buying
a USB keyboard :-)

Schlomo
