Description ndv 2006-10-24 18:04:42 UTC

The savage driver and possibly the hardware itself is not supporting a function
"non power of two textures" nor a software workaround.
This prevents (at least) Beryl/Compiz to work with 3D accelerated hardware with
(but not limited to) SuperSavage or Twister (KN 133) chips [S3 Savage "family"].
the displayed error is:
"beryl: Support for non power of two textures missing".
Although it may be clearly a Beryl/Compiz bug, may be that a workaround can be
made in the driver side.
thank you

Unfortunately, the hardware doesn't support NPOT textures.  It would probably be
a better idea to teach compiz/beryl to use regular POT textures then to use
software NPOT textures.  POT textures would be wasteful memory-wise, but but
should work fine.
