Dual-screen setup on a Mobility FireGL 7000M7

Hallo!

I used to have a two-screen setup (0.0 and 0.1) with two device-sections
respectively. Since I updated Xorg from 1.3.0 to 1.4.2 that setup does
not work any more.

When I plug in the external TFT to VGA-0, the radeon-driver seems to get
confused and "forgets" about the other connectors (in special, LVDS).
xrandr tells me there exists only VGA-0, if the server was not running
before the plugin.
If the server was already running when I plug in VGA-0, xrandr detects
the new monitor and the supported modes correctly.

A look in the Xorg.0.log shows the driver detects the LVDS-panel
correctly, but then the first instance of the driver "RADEON(0)" says
DVI-0 is connected, while the second instance "RADEON(1)" says VGA-0 is.


In single-screen setup Port0 is VGA, Port1 DVI-D, Port2 LVDS and Port3 STV.

Is there a way to tell the driver instance explicitally what connector
to use?





Saluti!

Ludwig
