I've tried 16 bit ambient, tried to change the resolution, etc, and it still hangs.

I've compiled the tinygl examples, and none of them work ("Failed to open Glut window").

However some programs that use 3D (like MangoQuest) run without problems, and the textures don't look "pixelized", so there must be a sign that mipmapping is working...

I will try with another card...
