X no me cambia de resolución.

[Frostwarrior]

Resulta que a veces cuando X inicia desde gdm, se pone medio tonto en lo que respecta a cambiar de resolucion.
Trato de cambiar incluso con xrandr y nada.

Lo killeo/logouteo, restartea X y la res me anda perfectamente.

aca el xorg.conf:

# cat /etc/X11/xorg.conf | grep -v '#' | grep "."

[Rumpelstiltskin]
