Dual-screen setup on a Mobility FireGL 7000M7

Fri Aug 8 03:53:01 PDT 2008

Hallo!

I am trying to (re-) setup Zaphod-mode one more time.
After I found the device-sctions had the same identifier, I am back to
the original problem: LVDS is off, image only on the 2nd head.

There is a panel connected at the LVDS port, and there is one at the
VGA-0 port. The notebook only has one more S-Video connector.

The setup is as follows:
(==) ServerLayout "Default Layout"
(**) |-->Screen "Default Screen" (0)
(**) |   |-->Monitor "Generic Monitor 0"
(**) |   |-->Device "ATI Technologies Inc Radeon RV200 LX [Mobility 
FireGL 7800 M7] 0"
(**) |-->Screen "External Screen" (1)
(**) |   |-->Monitor "Generic Monitor 1"
(**) |   |-->Device "ATI Technologies Inc Radeon RV200 LX [Mobility 
FireGL 7800 M7] 1"

On initliaization I get the following messages:

And I do not get a second screen:
ludwig at client16:~$ DISPLAY=":0.1" icewm-gnome
IceWM: using /home/ludwig/.icewm for private configuration files
IceWM: Can't open display: :0.1. X must be running and $DISPLAY set.
ludwig at client16:~$

The module I run has the following version:
(II) LoadModule: "ati"
(II) Loading /usr/lib/xorg/modules/drivers//ati_drv.so
(II) Module ati: vendor="X.Org Foundation"
         compiled for 1.4.2, module version = 6.9.0
         Module class: X.Org Video Driver
         ABI class: X.Org Video Driver, version 2.0
(II) LoadModule: "radeon"
(II) Loading /usr/lib/xorg/modules/drivers//radeon_drv.so
(II) Module radeon: vendor="X.Org Foundation"
         compiled for 1.4.2, module version = 4.3.0
         Module class: X.Org Video Driver
         ABI class: X.Org Video Driver, version 2.0

There is no difference if I set up "ati" or "readeon" driver directly in 
the xorg.conf.

Any hint, what to do?

Saluti!
