utility for switching the GLX implementation
In setups with several GLX providers (e.g. the free MESA implementation and proprietary graphics hardware vendor implementations) this utility allows one to switch between the different implementations.
Use 'update-glx --config glx' to select an implementation.
In addition to updating the alternatives, this will trigger further actions needed to complete the switch.
