Radeon MultiHead no xorg para FC5. So um monitor liga

Amigos,

Tenho um HP-Compaq NX9005. Laptop com uma placa de video Radeon 320M. Ele tem uma saida de video CRT para ligar outro monitor.
Plugo um monitor e configuro xorg para usar 2 monitores 2 devices e 2 screens. Dai a tela fica estendida, percebo movendo o mouse para a direita q ele se move bem para a direita, como se fosse para o segundo monitor, mas o segundo monitor fica desligado.

Ja troquei a opcao de LVDS, CRT para CRT,LVDS. Ja tentei muitas coisas. Se troco, ele acende o CRT e apaga o LCD do Lap. Nao consigo deixar os 2 ligados para usar a area estendida.

Alguem ja teve este problema, como resolveu. No windows o mesmo problema se resolve teclando Fn+F5, mas a tecla FN no linux nao faz funcao alguma, Nao sei se pode ser um caminho.

Muito obrigado,

Segue meu xorg.conf:

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))

# To disable the XKEYBOARD extension, uncomment XkbDisable.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
