On Intel HW, you can get turn TFP on by exporting LIBGL_ALWAYS_INDIRECT=1; how well the TFP will work depends on how recent your drivers is; at least in theory it should work OK on a 945 card with the current drivers. > (2) If yes for (1), can I get clutter to use GLX TFP by running a > software emulation? MESA? IIRC yes, but the last time I tried using Mesa, the OpenGL performance was abysmal. > (3) What is the fallback in metacity-clutter if GLX TFP is not available > - XShm? If XShm is supported, Clutter uses XShm, it not it falls back further onto XGetImage. Tomas -- To unsubscribe send a mail to [email protected]
