OpenGL hardware acceleration with FreeBSD 5.3

[Geoff Glasson]

Michael,

This might sound like a stupid question but...Did you load the DRI kernel 
module for the card before start the X server?

3D acceleration under X is a two part system.  There is the X server and the 
DRI module for X, but it also requires a kernel module for the hardware being 
accelerated.  

The main DRI web site is at: http://dri.sourceforge.net

There is also Eric Anholt's web site which is a little out of date, but you 
might find the troubleshooting section of use.  
http://people.freebsd.org/~anholt/dri/

Regards...Geoff
