configuracion del xorg y gdm

[Edward Carrasco]

estoy tratando de configurar una pc con ubuntu para que trabaje con
dos monitores dos teclados y dos mouse y con sus respectivas sesiones,
el problema
me resulta que al iniciar esta dos sesiones solo me responden el
teclado y el mouse de la que carga ultima (algo asi como si esta
bloqueara el teclado y mouse de la primera).
eh provado de todo y buscado sin exito por ahi derepente me falta
algo, si alguien antes lo a echo haber que alcance me puede dar.
espero su ayuda.
les mando los archivos de configuracion de xorg.conf y gdm.conf
