multihead layout - external monitor and lcd laptop
 

warning: Debian newb

setup:

debian
minimal install
gdm/icewm
I'm trying to setup dual monitors.
I have a laptop lcd screen and an external crt monitor.

The config file below loads fine without any parsing errors and gdm loads..



Problem:

Using my edited config file below the external monitor properly loads the left side of my icewm when i start gdm but the lcd screen - it stays blank as if it was off.

Questions:
Can anyone spot out what i did wrong?
Can anyone redirect me to setting up an LCD screen with an external monitor? Ive looked around a bit now.

Partial newb solutions that I am going to try next:
maybe the depth/resolution has to be the same to load properly?
xinerama, something i need to apt or is it packaged with the xserver stuff?
try setting up vga on the external monitor, even though the ati card should work on both?

Thanks in advance,
+_+
