I've put a screenshot of the misrendered sphere at http://web.hexapodia.org/~adi/nurbsphere.png I got that result on a fairly standard RedHat 7.1 system, but I can't tell if it's using Mesa (client-side rendering) or indirect-software rendering. % ldd ./a.out|head -5 libGLU.so.1 => /usr/lib/libGLU.so.1 (0x40024000) libGL.so.1 => /usr/lib/libGL.so.1 (0x40038000) libm.so.6 => /lib/i686/libm.so.6 (0x4029a000) libc.so.6 => /lib/i686/libc.so.6 (0x402be000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x403ee000) % ls -l /usr/lib/libGL*.so lrwxrwxrwx 1 root root 19 Sep 10 2001 /usr/lib/libGL.so -> libGL.so.1.2.030401* lrwxrwxrwx 1 root root 20 Sep 10 2001 /usr/lib/libGLU.so -> libGLU.so.1.1.030401* % rpm -qf /usr/lib/libGL.so Mesa-devel-3.4-13 % rpm -qa|grep Mesa Mesa-3.4-13 Mesa-devel-3.4-13 % glxinfo display: :0.0 screen:0 direct rendering: No server glx vendor string: SGI server glx version string: 1.2 server glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context client glx vendor string: SGI client glx version string: 1.2 client glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_ARB_get_proc_address GLX extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context OpenGL vendor string: VA Linux Systems, Inc.
