I post this message also to dri users mailing list.
However I post also to this list because I think that
it could be more appropriate (the problem appears
when I try to launch glxgears with dri enabled). I have
some trouble trying to make dri works with my card. It is a S3 savage 4 card with 16384 k video memory.
Suggestions about what to do (recompile, re-configure anything) could be useful..
I include logs here (I follow dri.freedesktop.org steps on troubleshooting):

> glxinfo | grep "direct rendering"
direct rendering: Yes
lsmod lists these modules : savage, drm, via_agp, agpart, i2c_savage4, i2c_algo_bit, i2c_viapro, i2c_core
All these with:
- Slackware 11.0, kernel, X.org 6.9.0, savage_dri.so driver downloaded from snapshots (savage-20060403-linux.i386.tar.bz2),
  OpenGL renderer string: Mesa DRI Savage4 20050829 AGP 1x x86/MMX/SSE
the computer hangs with glxgears after a little movement of mechanics.
I tried also with:
- Foresight 1.0, kernel, X.org 7.1.1
glxinfo complains : "libGL warning: 3D driver claims to not support visual 0x4B", so does glxgears but then hangs.
- Zenwalk, kernel, X.org 7.1.1
launching glxgears appears a black window (but no hangs).
