[GRLUG] Notebook with ATI chip, dual-screens, XGL?

[Benjamin Eavey]

I'm setting up a new HP notebook I just received through work (Compaq 
nc8430), and it's *almost* working the way I want it to.  Using Ubuntu 
6.10 as the distro.  I have have the main LCD display running at 
1680x1050 using the fglrx driver from ATI, and I have a second monitor 
attached to the VGA port running at 1280x1024 for a nice dual-screen 
setup.  No problem there.

Last night, I got XGL working (can't use AIGLX with ATI) on the notebook 
display.  Excellent.  Today, I decided to try and get XGL working across 
the dual displays, but so far, I haven't had any luck.  There isn't much 
out there on Google for ATI chips, although there are plenty of people 
who have it working with NVidia.

Does anyone have any experience with this stuff?  Specifically, has 
anyone successfully created an XGL dual-screen setup using an ATI card? 
  The notebook comes with a X1600 chip, if it makes any difference.

I'm starting to think this can't be done, but if anyone has any 
suggestions, I'm all ears...

Thanks!
