Support is not added for new X server versions until after the video driver ABI is frozen, which usually happens at the release candidate stage. Prerelease versions that are not release candidates, such as "1.10.99.1", are not supported.</p> <p>If you are setting up the X Window System for the first time, it is often easier to begin with one of the open source drivers that ships with XFree86 and X.Org (either "vga", "vesa", or "fbdev"). Once your system is operating properly with the open source driver, you may then switch to the NVIDIA driver.</p> <p>These software packages may also be available through your Linux distributor.</p> </div> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href= "introduction.html">Prev</a> </td> <td width="20%" align="center"><a accesskey="u" href= "installationandconfiguration.html">Up</a></td> <td width="40%" align="right"> <a accesskey="n" href= "selectdriver.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top"> Chapter 1.
