Using the XRandR Extension</h2> </div> </div> </div> <p>X.Org version X11R6.8.1 contains support for the rotation component of the XRandR extension, which allows screens to be rotated at 90 degree increments.</p> <p>The driver supports rotation with the extension when 'Option "RandRRotation"' is enabled in the X config file.</p> <p>Workstation RGB or CI overlay visuals will function at lower performance and the video overlay will not be available when RandRRotation is enabled.</p> <p>You can query the available rotations using the 'xrandr' command line interface to the RandR extension by running:</p> <pre class="screen"> xrandr -q </pre> <p>You can set the rotation orientation of the screen by running any of:</p> <pre class="screen"> xrandr -o left xrandr -o right xrandr -o inverted xrandr -o normal </pre> <p>Rotation may also be set through the nvidia-settings configuration utility in the "Rotation Settings" panel.</p> <p>SLI and rotation are incompatible. Rotation will be disabled when SLI is enabled.</p> <p>TwinView and rotation can be used together, but rotation affects the entire desktop. This means that the same rotation setting will apply to both display devices in a TwinView pair. Note also that the <code class="computeroutput">TwinViewOrientation</code> option applies before rotation does. For example, if you have two screens side-by-side and you want to rotate them, you should set <code class="computeroutput">TwinViewOrientation</code> to <code class="computeroutput">Above</code> or <code class= "computeroutput">Below</code>.</p> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href= "configtvout.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= "configlaptop.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top"> Chapter 16.
