In Squeeze the support for dual monitors changed.  It is no longer in
the configuration file, although it can be optionally placed there.
Now multiple monitor a userland operation using the xrandr interface.
This is nice actually and allows useful scripted configurations.  Use
the 'xrandr --query' to print attached device information and then use
the device information to specify where the monitors are placed in the
larger logical screen.

I have the following in my init files.  I will avoid mentioning the
file I am using because I doubt you are launching the same way and it
would just cause confusion.  But this is how I turn on dual monitor
support these days.

if xrandr --query | grep -q HDMI2; then
  xrandr --auto --output HDMI2 --right-of HDMI1
