You will need to reinstall the package:x11/nvidia-driver[] package so glx is built again.

+[[x-wayland]]
+== Wayland on FreeBSD
+Wayland is a new software for supporting desktops, but it differs from Xorg in several important ways.
+First, Wayland is not an X server; it is a protocol that acts as an intermediary between clients such as the X server and applications that run in the graphical environment.
+Since Wayland is not an X server, traditional X screen connections will need to utilize other methods such as VNC or RDP for remote desktop management. Second, it can manage composite communications between clients and a compositor as a separate entity which does not need to support the X protocols. The adage of doing one thing and do it well seems to be a primary goal of the developers.
+
+Wayland is relatively new, and not all software has been updated to run natively without `Xwayland` support. Currently, a lot of software will function with minimal issues on Wayland, including Firefox.
+And a few desktops are also available, such as the Compiz Fusion replacement, known as wayfire, and the i3 window manager replacement, Sway.
+
+For compositors, a kernel supporting the man:evdev[4] driver must exist to utilize the keybinding functionality.
+This is built into the [.filename]#GENERIC kernel by default; however, if it has been customized and man:evdev[4] support was stripped out, the man:evdev[4] module will need to be loaded.
+In addition, users of `Wayland` will need to be members of the `video` group.
+To quickly make this change, use the `pw` command:
+
+[source,shell]
+----
+pw groupmod video -m user
+----
+
+Installing Wayland is simple; there is not a great deal of configuration for the protocol itself.
+Most of the composition will depend on the chosen compositor.
+By installing `seatd` now, a step is skipped as part of the compositor installation and configuration as `seatd` is needed to provide access to certain device access to non-root users.
+All of the compositors described here should work with package:[graphics/drm-kmod] open source drivers; however, the NVidia graphics cards may have issues when using the proprietary drivers.
+Begin by installing the following packages:
+
+[source,shell]
+----
+# pkg install wayland seatd
+----
+
+Once the protocol and supporting packages have been installed, a compositor must create the user interface.
+Several compositors will be covered in the following sections. All compositors using Wayland will need a runtime directory defined in the environment, which can be achieved with the following command in the bourne shell:
+
+[source,shell]
+----
+% export XDG_RUNTIME_DIR=/var/run/user/`id -u`
+----
+
+It is important to note that most compositors will search the XDG_RUNTIME_DIR directory for the configuration files.
+In the examples included here, a parameter will be used to specify a configuration file in [.filename]#~/.config# to keep temporary files and configuration files separate.
+It is recommended that an alias be configured for each compositor to load the designated configuration file.
+
+[WARNING]
+====
+It has been reported that ZFS users may experience issues with some Wayland clients because they need access to `posix_fallocate()` in the runtime directory.
+While the author could not reproduce this issue on their ZFS system, a recommended workaround is not to use ZFS for the runtime directory and instead use `tmpfs` for the [.filename]#/var/run# directory.
+In this case, the `tmpfs` file system is used for [.filename]#/var/run# and mounted through the command `mount -t tmpfs tmpfs /var/run` command and then make this change persist across reboots through [.filename]#/etc/fstab#.
+The XDG_RUNTIME_DIR environment variable could be configured to use [.filename]#/var/run/user/$UID# and avoid potential pitfalls with ZFS.
+Consider that scenario when reviewing the configuration examples in the following sections.
+====
+
+The seatd daemon manages access to shared system devices for non-root users; this includes graphics cards.
+To enable and start the `seatd` daemon now, and on system initialization:
+
+[source,shell]
+----
+# sysrc seatd_enable=”YES”
+# service seatd start
+----
+
+Afterward, a compositor, which is similar to an X11 desktop, will need to be installed for the GUI environment.
+Three are discussed here, including basic configuration options, setting up a screen lock, and recommendations for more information.
+
+=== The Wayfire Compositor
+
+Wayfire is a compositor that aims to be lightweight and customizable.
+Several features are available, and it brings back several elements from the previously released Compiz Fusion desktop.
+All of the parts look beautiful on modern hardware. To get Wayfire up and running, begin by installing the required packages:
+The `alacritty` package provides a terminal emulator.
+Still, it is not completely required as other terminal emulators such as `kitty`, and XFCE-4 `Terminal` have been tested and verified to work under the Wayfire compositor.
+Wayfire configuration is relatively simple; it uses a file that should be reviewed for any customizations.
+To begin, copy the example file over to the runtime environment configuration directory and then edit the file:
+Within the configuration file, items like the famous `cube` are pre-configured, and there are instructions to help with the available settings.
+A few primary settings of note include:
+
+[.programlisting]
+....
+[output]
+mode = 1920x1080@60000
+position = 0,0
+transform = normal
+scale = 1.000000
+....
+
+In this example, from the configuration file, the screen's output should be the listed mode at the listed hertz.
+For example, the mode should be set to `widthxheight@refresh_rate`.
+The position places the output at a specific pixel location specified.
+The default should be fine for most users.
+Finally, transform sets a background transform, and scale will scale the output to the specified scale factor.
+The defaults for these options are generally acceptable; for more information, see the documentation.
+
+As mentioned, Wayland is new, and not all applications work with the protocol yet.
+At this time, `sddm` does not appear to support starting and managing compositors in Wayland.
+The `swaylock` utility has been used instead in these examples. The configuration file contains options to run `swayidle` and `swaylock` for idle and locking of the screen.
+This option to define the action to take when the system is idle is listed as:
+
+[.programlisting]
+....
+idle = swaylock
+....
+
+And the lock timeout is configured using the following lines:
+
+[.programlisting]
+....
+[idle]
+toggle = <super> KEY_Z
+screensaver_timeout = 300
+dpms_timeout = 600
+....
+
+The first option will lock the screen after 300 seconds, and after another 300, the screen will shut off through the `dpms_timeout` option.
+
+One final thing to note is the <super> key.
+Most of the configuration mentions this key, and it is the traditional `Windows` key on the keyboard.
+Most keyboards have this super key available; however, it should be remapped within this configuration file if it is not available.
+For example, to lock the screen, press and hold the super key, the kbd:[shift] key, and press the kbd:[escape] key.
+nless the mappings have changed, this will execute the swaylock application.
+The default configuration for `swaylock` will show a grey screen; however, the application is highly customizable and well documented.
+In addition, since the swaylock-effects is the version that was installed, there are several options available such as the blur effect, which can be seen using the following command:
+
+[source,shell]
+----
+% swaylock --effect-blur 7x5
+----
+
+There is also the `--clock` parameter which will display a clock with the date and time on the lock screen.
+When package:x11/swaylock-effects[] was installed, a default [.filename]#pam.d# configuration was included.
+It provides the default options that should be fine for most users.
+More advanced options are available; see the PAM documentation for more information.
+
+At this point, it is time to test Wayfire and see if it can start up on the system.
+Just type the following command:
+
+[source,shell]
+----
+% wayfire -c ~/.config/wayfire/wayfire.ini
+----
+
+The compositor should now start and display a background image along with a menu bar at the top of the screen.
+Wayfire will attempt to list installed compatible applications for the desktop and present them in this drop-down menu; for example, if the XFCE-4 file manager is installed, it will show up in this drop-down menu.
+If a specific application is compatible and valuable enough for a keyboard shortcut, it may be mapped to a keyboard sequence using the [.filename]#wayfire.ini# configuration file.
+Wayfire also has a configuration tool named Wayfire Config Manager.
+It is located in the drop-down menu bar but may also be started through a terminal by issuing the following command:
+
+[source,shell]
+----
+% wcm
+----
+
+Various Wayfire configuration options, including the composite special effects, maybe enabled, disabled, or configured through this application.
+In addition, for a more user-friendly experience, a background manager, panel, and docking application may be enabled in the configuration file:
+
+[.programlisting]
+....
+panel = wf-panel
+dock = wf-dock
+background = wf-background
+....
+
+[WARNING]
+====
+Changes made through `wcm` will overwrite custom changes in the [.filename]#wayfire.ini# configuration file.
+The [.filename]#wayfire.ini# file is highly recommended to be backed up so any essential changes may be restored.
+====
+
+Finally, the default launcher listed in the [.filename]#wayfire.ini# is `wofi`, which is not available on FreeBSD.
+This can be changed to any Wayland supporting launcher. The following line needs to be updated inside of [.filename]#wayfire.ini#.
+In this next example, the launcher has been changed to `lavalauncher`.
+An example configuration file for `lavalauncher` is available at the end of this section.
+
+[.programlisting]
+....
+command_launcher = lavalauncher
+....
+
+=== The Hikari Compositor
+
+The Hikari compositor uses several concepts centered around productivity, such as sheets, workspaces, and more.
+In that way, it resembles a tiling window manager.
+Breaking this down, the compositor starts with a single workspace, which is similar to virtual desktops.
+Hikari uses a single workspace or virtual desktop for user interaction. The workspace is made up of several views, which are the working windows in the compositor grouped as either sheets or groups.
+Both sheets and groups are made up of a collection of views; again, the windows that are grouped together.
+When switching between sheets or groups, the active sheet or group will become known collectively as the workspace.
+The manual page will break this down into more information on the functions of each but for this document, just consider a single workspace utilizing a single sheet.
+Hikari installation will comprise of a single package, package:x11-wm/hikari[], and a terminal emulator `alacritty`:
+
+[source,shell]
+----
+# pkg install hikari alacritty
+----
+
+[NOTE]
+====
+Other shells, such as `kitty` or the Plasma `Terminal`, will function under Wayland. Users should experiment with their favorite terminal editor to validate compatibility.
+====
+
+Hikari uses a configuration file, [.filename]#hikari.conf#, which could either be placed in the XDG_RUNTIME_DIR or specified on startup using the `-c` parameter.
+An autostart configuration file is not required but may make the migration to this compositor a little easier.
+Beginning the configuration is to create the Hikari configuration directory and copy over the configuration file for editing:
+The configuration is broken out into various stanzas such as ui, outputs, layouts, and more.
+For most users, the defaults will function fine; however, some important changes should be made.
+For example, the $TERMINAL variable is normally not set within the user's environment.
+Changing this variable or altering the [.filename]#hikari.conf# file to read:
+
+[.programlisting]
+....
+terminal = "/usr/local/bin/alacritty"
+....
+
+Will launch the `alacritty` terminal using the bound key press.
+While going through the configuration file, it should be noted that the capital letters are used to map keys out for the user.
+For example, the kbd:[L] key for starting the terminal kbd:[L+Return] is actually the previously discussed super key or Windows logo key.
+Therefore, holding the kbd:[L/super/Windows] key and pressing kbd:[Enter] will open the specified terminal emulator with the default configuration.
+Mapping other keys to applications require an action definition to be created.
+For this, the action item should be listed in the actions stanza, for example:
+
+[.programlisting]
+....
+actions {
+ terminal = "/usr/local/bin/alacritty"
+ browser = "/usr/local/bin/firefox"
+}
+....
+
+Then an action may be mapped under the keyboard stanza, which is defined within the bindings stanza:
+
+[.programlisting]
+....
+bindings {
+ keyboard {
+SNIP
+ "L+Return" = action-terminal
+ "L+b" = action-browser
+SNIP
+....
+
+After Hikari is restarted, holding the Windows logo button and pressing the kbd:[b] key on the keyboard will start the web browser.
+The compositor does not have a menu bar, and it is recommended the user set up, at minimal, a terminal emulator before migration.
+The manual page contains a great deal of documentation it should be read before performing a full migration.
+Another positive aspect about Hikari is that, while migrating to the compositor, Hikari can be started in the Plasma and GNOME desktop environments, allowing for a test-drive before completely migrating.
+
+Locking the screen in Hikari is easy because a default [.filename]#pam.d# configuration file and unlock utility are bundled with the package.
+The key binding for locking the screen is kbd:[L] (Windows logo key)+ kbd:[Shift] + kbd:[Backspace].
+It should be noted that all views not marked public will be hidden.
+These views will never accept input when locked but beware of sensitive information being visible.
+For some users, it may be easier to migrate to a different screen locking utility such as swaylock-effects, discussed in this section.
+To start Hikari, use the following command:
+
+[source,shell]
+----
+% hikari -c ~/.config/hikari/hikari.conf
+----
+
+=== The Sway Compositor
+
+[NOTE]
+===
+The Sway window manager is not expected to work on propriety NVidia drivers.
+This is an upstream choice, so the package:x11/nvidia-driver[] should be used if possible.
+===
+
+The Sway compositor is a tiling compositor that attempts to replace the i3 windows manager.
+It should work with the user's current i3 configuration; however, new features may require some additional setup.
+In the forthcoming examples, a fresh installation without migrating any i3 configuration will be assumed.
+To install Sway and valuable components, issue the following command as the root user:
+In the previous example, the `xkb` rules for man:evdev[4] events are loaded, and the $mod key is set to the Windows logo key for the key bindings.
+Next, the terminal emulator was set to be `alacritty`, and a screen lock command was defined; more on this later.
+The output keyword, the mode, the position, a background wallpaper, and Sway is also told to stretch this wallpaper to fill out the screen.
+Finally, `swaylock` is set to daemonize and lock the screen after a timeout of 300 seconds, placing the screen or monitor into sleep mode after 600 seconds.
+The locked background color of 000000, which is black, is also defined here.
+Using swaylock-effects, a clock may also be displayed with the `--clock` parameter.
+See the manual page for more options.
+The man:sway-output[5] manual page should also be reviewed; it includes a great deal of information on customing the output options available.
+
+While in Sway, to bring up a menu of applications, hold the Windows logo key (mod) and press the kbd:[d] key.
+The menu may be navigated using the arrow keys on the keyboard.
+There is also a method to manipulate the layout of the bar and add a tray; read the man:sway-bar[5] manual page for more information.
+The default configuration adds a date and time to the upper right-hand corner.
+See the `Bar` stanza in the configuration file for an example.
+By default, the configuration does not include locking the screen outside of the example above, enabling a lockout timer.
+Creating a lock key binding requires the following line to the `Key bindings` section:
+
+[.programlising]
+....
+# Lock the screen manually
+bindsym $mod+Shift+Return exec $lock
+....
+
+Now the screen may be locked using the combination of holding the Windows logo key, pressing and holding shift, and finally pressing return.
+When Sway is installed, whether from a package or the FreeBSD Ports Collection, a default file for [.filename]#pam.d# was installed.
+The default configuration should be acceptable for most users, but more advanced options are available.
+Read through the PAM documentation for more information.
+
+Finally, to exit Sway and return to the shell, hold the Windows logo key, the shift key, and press the kbd:[e] key.
+A prompt will be displayed with an option to exit Sway.
+During migration, Sway can be started through a terminal emulator on an X11 desktop such as Plasma.
+This makes testing different changes and key bindings a little easier prior to fully migrating to this compositor.
+To start Sway, issue the following command:
+
+[source,shell]
+----
+% sway -c ~/.config/sway/config
+----
+
+=== Using Xwayland
+
+When installing Wayland, the package:x11-servers/xwayland-devel[] package should have also been installed.
+If the [.filename]#/usr/local/bin/Xwayland# file does not exist, install it using the following command:
+
+[source,shell]
+----
+# pkg install xwayland-devel
+----
+
+[NOTE]
+====
+The development version of Xwayland is recommended and was most likely installed with the Wayland package.
+Each compositor has a method of enabling or disabling this feature.
+====
+
+Once `Xwayland` has been installed, configure it within the chosen compositor.
+For Wayfire, the following line is required in the [.filename]#wayfire.ini# file:
+
+[.programlisting]
+....
+xwayland = true
+....
+
+For the Sway compositor, `Xwayland` should be enabled by default.
+Even so, it is recommened to manually add a configuration line in the [.filename]#~/.config/sway/config# like the following:
+
+[.programlisting]
+.....
+xwayland enable
+.....
+
+Finally, for Hikari, no changes are needed.
+Support for `Xwayland` is build in by default.
+To disable that support, rebuild the package from the ports collection and disable Xwayland support at that time.
+
+After these changes are made, start the compositor at the command line and execute a terminal from the key bindings.
+Within this terminal, issue the `env` command and search for the `DISPLAY` variables.
+If the compositor was able to properly start the Xwayland X server, these environment variables should look similar to the following:
+
+[source,shell]
+----
+% env | grep DISPLAY
+----
+
+[.programlisting]
+....
+WAYLAND_DISPLAY=wayland-1
+DISPLAY=:0
+....
+
+In this output, there is a default Wayland display and a display set for the Xwayland server.
+Another method to verify that `Xwayland` is functioning properly is to use install and test the small package:[x11/eyes] and check the output.
+If the `xeyes` application starts and the eyes follow the mouse pointer, Xwayland is functioning properly.
+If an error such as the following is displayed, something happened during the `Xwayland` intitialization and it may need reinstalled:
+
+[.programlisting]
+....
+Error: Cannot open display wayland-0
+....
+
+[WARNING]
+====
+A security feature of Wayland is that, without running an X server, there is not another network listener.
+Once `Xwayland` is enabled, this security feature is no longer applicable to the system.
+====
+
+For some compositors, such as Wayfire, `Xwayland` may not start properly.
+As such, `env` will show the following information for the `DISPLAY` environment variables:
+
+[source,shell]
+----
+% env | grep DISPLAY
+----
+
+[.programlisting]
+....
+DISPLAY=wayland-1
+WAYLAND_DISPLAY=wayland-1
+....
+
+Even though `Xwayfire` was installed and configured, X11 applications will not start giving a display issue.
+To work around this, verify that there is already an instance of `Xwayland` using a UNIX socket through these two methods.
+First, check the output from `sockstat` and search for X11-unix:
+
+[source,shell]
+----
+% sockstat | grep x11
+----
+
+There should be something similar to the following information:
+This can be further verified by attempting to execute `Xwayland` manually within a terminal emulator running under the compositor:
+
+[source,shell]
+----
+% Xwayland
+----
+
+If an X11 socket is already available, the following error should be presented to the user:
+
+[.programlisting
+....
+(EE)
+Fatal server error:
+(EE) Server is already active for display 0
+ If this server is no longer running, remove /tmp/.X0-lock
+ and start again.
+(EE)
+....
+
+Since there is an active X display available using display zero, the environment variable was just set improperly, to fix this, change the `DISPLAY` environment variable to `:0` and attempt to execute the application again.
+The following example uses package:mail/claws-mail[] as the application which needs the `Xwayland` service:
+
+[source,shell]
+----
+export DISPLAY=:0
+----
+
+After this change, the package:mail/claws-mail[] application should now start using `Xwayland` and function as expected.
+
+=== Remote Desktop Using VNC
+
+Earlier in this document it was noted that Wayland does not provide the same X server style access as Xorg provides.
+Instead, users are free to pick and choose a remote desktop protocol such as RDP or VNC.
+The FreeBSD Ports collection includes the `wayvnc`, which will support wlroots based compositors such as the ones discussed here.
+This application may be installed using:
+
+[source,shell]
+----
+# pkg install wayvnc
+----
+
+Unlike some other packages, `wayvnc` does not come with a configuration file.
+Thankfully, the manual page documents the important options and they may be extrapolated into a simple configuration file:
+
+[.programlisting]
+....
+address=0.0.0.0
+enable_auth=true
+username=username
+password=password
+private_key_file=/path/to/key.pem
+certificate_file=/path/to/cert.pem
+....
+
+The key files will need to be generated, and it is highly recommended they be used for increased security of the connection.
+When invoked, wayvnc will search for the configuration file in [.filename]#~/.config/wayvnc/config#.
+This could be overwritten using the `-C configuration_file` option when starting the server.
+Thus, to start the `wayvnc` server, issue the following command:
+
+[source,shell]
+----
+% wayvnc -C ~/.config/wayvnc/config
+----
+
+[NOTE]
+====
+At the time of this writing, there is no rc.d script to start `wayvnc` on system initialization.
+If that functionality is desired, a local startup file will need to be created.
+This is probably a feature request for the port maintainer.
+====
+
+=== Useful Utilities
+
+One useful Wayland utility which all compositors can make use of is the waybar.
+While Wayfire does come with a launch menu, an easy-to-use and fast taskbar is a good accessory for any compositor or desktop manager.
+A Wayland compatible taskbar that is fast and easy to configure is waybar.
+To install the package and a supporting audio control utility, issue the following command:
+
+[source,shell]
+----
+# pkg install pavucontrol waybar
+----
+
+To create the configuration directory and copy over a default configuration file, execute the following commands:
