[opensuse-xorg] xinerama not working with 10.3/64-bit

21 Jun 2008

      Hi all,

I'm new to this list, though I've run Suse and opensuse for a couple of 
years now, and linux for much longer than that.

I manage a small cluster of machines that ran a mix of suse 9.1 to 10.1. 
I finally was able to successfully bring them all up to x86-64 opensuse 
10.3.

The last machine I worked on was originally a 32-bit installation. The 
CPU was upgraded to 64 bit. Up till this point, I was able to drive a 
pair of viewsonis vp 181s with a matrox 450 with Xinerama in "clone off" 
mode, to esssentially give an extended desktop.

With 10.3, I am unable to re-create that setup.  I am stuck with X in 
clone/mirror mode.

Below are the relevant parts of the xorg.conf. Am I missing something, 
or should I file a bug report ?

Thanks much folks.

cheers
