I don't think you can easily control which dri driver the server opens, but I might be wrong. So, if you have LIBGL_ALWAYS_SOFTWARE set and LIBGL_ALWAYS_INDIRECT unset, then you should get direct rendering with the swrast. To review, LIBGL_ALWAYS_INDIRECT: use the X server's GLX context. This used to mean you'd also get software rendering, but with AIGLX you'll probably get the hardware DRI driver. LIBGL_ALWAYS_SOFTWARE: tell libGL to use the software renderer. This only works with direct rendering because otherwise you're getting the DRI driver that the X server opened, and it's not controlled by this variable. -- Dan </pre> </blockquote> </body> </html>
