appropriate hardware driver for each screen on the local X display.
The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/
directory. Drivers are named with the convention <name>_dri.so where
-<name> is a driver such as "tdfx", "i810", "gamma", etc.
+<name> is a driver such as "radeon", "i965", "nouveau", etc.
The LIBGL_DRIVERS_DIR environment variable may be used to specify a
different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/.
libGL.so is thread safe. The overhead of thread safety for common,
single-thread clients is negligible. However, the overhead of thread
safety for multi-threaded clients is significant. Each GL API call

DRI drivers may not be. Please consult the documentation for a driver
to learn if it is thread safe.
