Su GDM non so, faccio sempre il login in shell, ma per -layout è molto
semplice.

Si tratta di moltiplicare le istanze "Screen" (e di conseguenza quelle
"Device" e "Monitor"). Dopodichè creare diversi "serverlayout" con
identificatori diversi e chiamarli ad esempio in questo modo:

$ startx -- -layout double

Attenzione che il primo doppio-dash è necessario perchè l'argomento
successivo venga letto da X e non da startx stesso!

Il layout che parte di default è il primo che sta scritto nel file
xorg.conf.

Allegato trovate il mio xorg.conf (scheda intel), per dubbi o
perplessità chiedete pure :)
