; {{Anchor|XWayland}} XWayland
: XWayland is a series of patches over the X.Org server codebase that implement an X server running upon the [[Wayland (display server protocol)|Wayland]] protocol. The patches are developed and maintained by the Wayland developers for compatibility with X11 applications during the transition to Wayland,<ref>{{cite web|title=X Clients under Wayland (XWayland)|url=http://wayland.freedesktop.org/xserver.html|publisher=Wayland Project|access-date=10 February 2014}}</ref> and were mainlined in version 1.16 of the X.Org Server in 2014.<ref name="xorgserver1160">{{cite web |url=http://lists.x.org/archives/xorg-announce/2014-July/002457.html |title=ANNOUNCE: xorg-server 1.16.0 |publisher=[[freedesktop.org]] |date=17 July 2014}}</ref> When a user runs an X application from within [[Wayland (display server protocol)|Weston]], it calls upon XWayland to service the request.<ref>

; {{Anchor|XQuartz}} XQuartz
: XQuartz is a series of patches from [[Apple Inc.]] to integrate support for the X11 protocol into their [[Quartz Compositor]], in a similar way to how XWayland integrates X11 into [[Wayland compositor]]s.
; Xspice
: Xspice is a device driver for the X.Org Server. It supports the QXL framebuffer device and includes a wrapper script<ref>{{cite web|url=http://cgit.freedesktop.org/xorg/driver/xf86-video-qxl/tree/README.xspice |title=XSpice README |publisher=Cgit.freedesktop.org |access-date=2013-10-25}}</ref> which makes it possible to launch an X.Org Server whose display is exported via the [[SPICE (protocol)|SPICE]] protocol. This enables use of SPICE in a remote desktop environment, without requiring [[Kernel-based Virtual Machine|KVM]] virtualization.
; Xephyr
: [[Xephyr]] is an X-on-X implementation. Since version 1.16.0, Xephyr serves as the primary development environment for the new 2D acceleration subsystem (Glamor), permitting rapid development and testing on a single machine.<ref name="xorgserver1160" />
; RandR
: '''RandR''' (''resize and rotate'') is a [[communications protocol]] written as an extension to the [[X Window System core protocol|X11]]<ref>{{cite web|url=http://cgit.freedesktop.org/xorg/proto/randrproto/tree/randrproto.txt|title=The X Resize, Rotate and Reflect Extension Version 1.3.1}}</ref> protocol. XRandR provides the ability to resize, rotate and reflect the [[root window]] of a screen. RandR is responsible for setting the screen refresh rate.<ref name="Tyler2008">{{cite book |last1=Tyler |first1=Chris |title=X Power Tools |date=2008 |publisher="O'Reilly Media, Inc." |isbn=9780596101954 |pages=86–87 |url=https://books.google.com/books?id=X9YRMIA899gC&q=%22XRandR%22+-wikipedia&pg=PA87 |access-date=14 September 2018 |language=en}}</ref> It allows for the control of multiple monitors.<ref name="Gultsch2009">{{cite journal |last1=Gultsch |first1=Daniel |title=Dual Image » Linux Magazine |journal=Linux Magazine |date=2009 |issue=106 |url=http://www.linux-magazine.com/Issues/2009/106/Multi-heading-with-RandR}}</ref>
