I'm new to DRI.
I just found out that the creator3d card isn't that bad of a card. It should even be able to accelerate 3d. So rebuilded my kernel (2.6.3) so I could load the ffb module. Now I only need X to use it. In the module section of XF86Config I load glx and dri. Both are loaded well without any errors. In /usr/X11R6/lib/modules/dri I see there is a driver
Now when I use that driver in the driver propertie of the card section in XF86Config, it says it can not be found. When I use the regular sunffb driver I can start X, but running glxinfo segfaults.
When I want to use DRI/DRM/DRX (what is it called these days?) what driver do I need to load for my card?

I can't comment on the kernel 2.6.3 problem, but I can comment on the rest.

The Segfault is bug 19776, which see. It is sparc specific, independent of
kernel version.

The short answer is that when you build xfree on sparc, of you want to
use (xfree's) opengl, you must apply the December 6, 12 patches during
the build process. is a variation on the same theme. is sunffb's helper
for hardware acceleration; it is not a Creator driver (which is sunffb).

xfree+sunffb try to load when you are set up like you describe.
Unfortunately, they can't. is not complete: it is supposed to
pretty much take over from sunffb in your situation, but the low-level code
to talk directly to the ffb card was never finished, and the interface between
the source module to do that and OpenGL is way out of date.

I don't know why xfree even tries to build because it doesn't
compile the critical source module. cannot ever load because
there is an unresolved external: the entry to to the module that won't
compile. :roll:

So, your best approach is to rebuild X with the 19776 fixes and to use
sunffb. Then glxinfo will spin its gears.

Hope this helps. (There is a detailed description of all this buried in 19776).
