===== OpenGL (libGL.so) =====

Different OpenGL drivers - Nvidia, Mesa, Intel - which one to choose?

Usually it's enough to use:

<code bash>LD_LIBRARY_PATH=/path/to/libgl # Ubuntu (/usr/lib/libGL.so)</code> 

There's also ''%%LIBGL_DRIVERS_PATH%%''. And if all doesn't work, you can still use ''%%LD_PRELOAD%%'' to load another libgl first.

But there is no guarantee, which libGL is used by which App to compile- and/or run-time.???
