Ok, I got multiseat working with ubuntu 9.10 with gdm-2.20 .
It cost me some time to figure out the gdmgreeter was crashing.(but not in gdm 
2.18)Changing this setting to gdmlogin works ok(but it's the old style debian 
greeter).I believe that gdm is too much attached to gnome,because with dual 
screens, not only the greeter is crashing also gnome-panel.
Maybe something to do with xrandr.
