Xephyr

<h2 id="features">Features</h2>
<p>Unlike the similar <i>Xnest</i>, Xephyr supports modern X extensions (even if the host server does not) such as composite, damage, and randr. It uses <a href="/facts/MIT-SHM/ho8xYnaK">SHM</a> images and shadow framebuffer updates to provide good performance. It also has a visual debugging mode for observing screen updates.
</p>
<h2 id="limitations">Limitations</h2>
<p><a href="/facts/Xorg/7AaPmYtV">Xorg</a>'s version of Xephyr uses only <a href="/facts/Software_rendering/NzSxPkSP">software rendering</a> for <a href="/facts/OpenGL/xQoMWePr">OpenGL</a>, but Feng Haitao has developed a <a href="https://github.com/fenghaitao/xserver-with-gl-accelerated-xephyr">forked version of Xephyr</a> which can do hardware-accelerated rendering if the underlying X server has the capability.
