SiS, DRI and DRM

[cckuo]

Would you please attach the dmesg and Xorg.0.log file?
I am not sure whether it was caused by improperly drm, dri loading or 3d
driver fail.
Sincerely Yours,
cckuo

When there is no DRM support, 3D falls back to using the software patch.
 I'm sure you also notice in that case that it's *much* slower.

As for problems with the SiS driver, I don't think it has gotten any
support in a long time.  Do you see errors in all applications (e.g.,
glxgears), or just some?  Could you post a link to a screen shot?  Could
you also post the output of glxinfo?
