Unofficial protocol requires the use of NVIDIA GLX libraries on both the client and the server. Note: GLX protocol is used when an OpenGL application indirect renders (i.e., runs on one computer, but submits protocol requests such that the rendering is performed on another computer). The above OpenGL extensions are fully supported when doing direct rendering.</p> <p>GLX visuals and FBConfigs are only available for X screens with depths 16, 24, or 30.</p> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href= "displaydevicenames.html">Prev</a> </td> <td width="20%" align="center"><a accesskey="u" href= "appendices.html">Up</a></td> <td width="40%" align="right"> <a accesskey="n" href= "dpi.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top"> Appendix C.
