Radeon Multi-Headed displays

[Jim Durham]

Hello,

Has anyone been successful in getting a Radeon Mobility 9000 chipset to work 
multiheaded with X on FreeBSD?

I have a Dell Inspiron 600M and I have X working nicely in "non-multiheaded" 
mode.

I have tried everything in the man page, tried a couple of XF86Config files 
from  folks who claim they work on their laptop, all to no avail. 

The external monitor works, but the laptop LCD screen stays blank unless you 
switch it manually using the function key, then the external monitor goes 
blank. When you switch back to the external monitor, it is in the loser 
resolution of the LCD (1025x768).

Here is a typical try at the monitor/screen/server layout portion of my  
XF86Config file.

Am I doing something really wrong or is this just broken? I am running X 
version 4.3.0  .  BTW, I have tried options "DPMS" and "NoDDC", etc.

-Jim
