Hola sectarios

La verdad es que no se muy bien como plantear mi problema, ya que no estoy 
seguro de lo que estoy haciendo mal. 

Hace un tiempo puse una segunta tarjeta de video al ordenador para poder 
aprovechar un viejo monitor que tenia cogiendo polvo. Edite el XF86Config-4 
para poner las dos tarjetas y los monitores y funcion� bien, porque podia pasar 
el raton de un monitor a otro (aunque no arrastrar ventanas y me apetecia 
bastante). Para hacer esto desinstal� el gdm y arrancaba las X con startx a 
pelo.

Hace dos dias hice un upgrade y se actualizaron bastantes paquetes de gnome 
(uso sid, por cierto) con lo que los escritorios del segundo monitor y el uso 
de aplicaciones se me fue al carajo. Me explico: Creo que antes se me abrian 
dos sesiones X :0.0 y :0.1  Ahora cuando abro una aplicacion en el segundo 
monitor, el cursor no se situa en esas aplicaciones aunque estas si responden a 
clics del raton (???) y ademas el raton baja unos centimetros al pasar de un 
monitor a otro

He instalado hoy el gdm y me he puesto a cacharrear con el gdm.conf y sobre 
todo con la seccion servers e intentando activar la opcion xinerama (porque 
hacer startx +xinerama me da error) y no he encontrado ninguna configuracion 
que haga lo que quiero (tener un mismo escritorio en los dos monitores y poder 
arrastrar ventanas de uno a otro)

No se si el problema esta en alguno de los ficheros de configuracion, en haber 
actualizado gnome o que. Inserto a continuacion los ficheros y perdon por la 
chapa que estoy metiendo.

Gracias
