When you download mesa, you also get a open source driver with it. I was trying to understand more about the internals on the driver acceleration e.g., what openGL APIs are accelerated etc. ? -mohan On Tue, Jul 8, 2008 at 4:25 PM, Gernot Ziegler <[email protected]> wrote: > Hej Mohan, > > Mesa is a purely software-based driver. > > Do you have any graphics card in your system?
