dual head v linuxu

rad bi uporabljal dual head v fedori sem zagnal system-config-display kar naj bi blo dovolj... pa mi se vedno uporablja samo en monitor... so mi rekl da bi moru peš popravlat /etc/X11/xorg.conf
zanima me če je to res pa kje oz kaj moram popravit a je to tuki?:


# Xorg configuration created by system-config-display
