Virtual reality is the process of simulating an environment for a user, using a variety of peripherals, head mounted displays or CAVEs, and trackers. Instead of showing you a static viewpoint from a screen, it renders your viewpoint relative to where you are standing, on a head-attached or projected surface, to give an effect identical to your own eyes.
A number of peripherals have been released or are about to be released recently which have brought affordable, extremely immersive virtual reality to everyone. Most of these peripherals have full or partial Linux support, and many have AUR packages.

Peripherals and toolkits
See Oculus Rift.
OpenVR is an effort by Valve to create an open API for VR development. Unfortunately, while the API is open, the actual default implementation (SteamVR) is not. Fortunately, OSVR (another, more open toolkit with support for a much wider variety of products via plugins) can work as an alternative OpenVR implementation via the OSVR-SteamVR plugin, letting you use any OSVR compatible peripherals with OpenVR compatible games and programs.
Install Steam, and from it install SteamVR from the tools menu.
Configuration or startup errors
SteamVR/OpenVR create a config directory ~/.openvr that can get misconfigured over the various versions. Delete that directory and completely uninstall/reinstall SteamVR.
It can also apparently have trouble accessing the Rift under some configurations. An alternative is to use the OSVR-SteamVR driver and the OSVR-Oculus-Rift plugin.
OSVR is a joint effort by Sensics, Inc (a long standing VR company) and Razer to create a completely or nearly completely open software API for VR, in which end developers only need to hook their individual headsets into a few functions in order to get first-rate support. It supports the widest variety of peripherals, as well as having extremely flexible config via the JSON config files.
It also provides a plugin which allows it to act as an OpenVR implementation, letting you use it to play OpenVR/SteamVR games with any peripherals it supports.
InstallAUR, and whatever plugins are neccesary to support your individual device. Currently available external plugins include:
If wish to use OSVR with SteamVR/OpenVR games and applications, installAUR and symlink the driver to your SteamVR installation.
Run the OSVR server and leave it running in the background, by calling it with
You may wish to customize the configuration to suit your individual needs.
To test that your installation is working and your trackers are available, install
OSVRTrackerView. You should see a set of axis for each tracker OSVR can pick up. If you do not, run
osvr_print_tree to see what trackers are available or if there is a configuration issue.
The Leap Motion is an incredibly affordable hand tracker which can easily be mounted on the faceplate of an HMD to allow you to interact with virtual objects. Unfortunately, the latest Orion software is not available for Linux while it is awaiting porting, so the currently available tracking is functional but excessively buggy. As such, it is only really suitable on Linux for social interaction, but seeing as it costs less than 1/10th what an HMD or equivalent tracking system, it is still a fairly useful device.
InstallAUR, AUR and optionally AUR.
To configure, enable and start
leapd.service and run
LeapControlPanel. To test that tracking works, run the
Playground demo included with the installation.
OpenHMD aims to provide a Free and Open Source API and drivers for immersive technology, such as head mounted displays with built in head tracking. The aim is to implement support for as many devices as possible in a portable, cross-platform package.
OpenHMD supports a wide range of devices such as Oculus Rift, HTC Vive, Sony PSVR, Deepoon E2 and others.
Bindings for .NET, Java, Perl, Python and Rust are available from third-parties.
It is possible to use OpenHMD with SteamVR. To do that, you need to installAUR and create symlink that points to the OpenHMD SteamVR driver inside your SteamVR drivers directory, e.g.:
ln -s /usr/lib/steamvr/openhmd ~/.steam/steam/steamapps/common/SteamVR/drivers/openhmd
Currently there are a handful of apps which work well on the Rift and Linux, with several of them being in the AUR.
Dolphin (original VR fork)
AUR is an emulator for Gamecube, with patches to allow it to have full headtracking stereoscopic rendering, as well as a number of customizations to make games work well out of the box in VR (for example, disabling culling functions to let you view the entire world).
Support has for the most part been discontinued, in light of the Dolphin project beginning to officially support OSVR upstream.
Dolphin (official OSVR support)
The Dolphin project has begun to work on adding support for VR officially using OSVR, available through the packageAUR. It can even use OSVR's path tree inputs as controller inputs, such that you can use a pinch or sixaxis controller input as a wiimote input. Support is limited in places however, as the fork is not as far along as the original Oculus-only fork was.
Games/Programs in Wine
A number of applications have some level of compatibility when using Wine, but often require some level of tweaks to make them function as expected.
AUR is a utility to patch up the differences between the Linux and Windows versions of the Oculus SDK when running Wine. It creates a shared memory context for the Wine application to use, letting the app access the native Oculus SDK. No installation of the SDK to the wineprefix appears to be necessary.
To get the best performance in Unity based games, ideally you should force them into OpenGL mode with the
-force-opengl. However this is not currently possible with an unpatched wine, as the WGL context it tries to force has some differences from a typical GLX context, as described here. Using the AUR package will allow you to run these games with native OpenGL, allowing you to play them with decent performance on your machine. Unfortunately they often try to change the video mode or mess with other settings, so supplying default screen settings may be neccesary. Additionally, since it is using native OpenGL, nvidia's __GL_THREADED_OPTIMIZATIONS may give a significant performance gain. Overall, the command should look something like this:
env __GL_THREADED_OPTIMIZATIONS=1 wine UnityGame.exe -screen-height 1080 -screen-width 1920 -popupwindow -force-opengl
Or when usingAUR:
env __GL_THREADED_OPTIMIZATIONS=1 oculus-wine-wrapper UnityGame.exe -screen-height 1080 -screen-width 1920 -popupwindow -force-opengl
Minecrift (Minecraft VR)
A guide is available here to run an existing Minecrift version with the very latest JRift (native java rift runtime) build. You will likely want to install an older version when using the Rift, as JRift has been updated continuously to match the Oculus SDK.
Additionally, many users have reported much better performance with JRE8, rather than JRE7.
"janusVR: an immersive, collaborative, multi-dimensional internet." JanusVR is an application that lets you explore 3D websites in a multiplayer experience. An AUR package is available:AUR
The AUR package does not automatically update when JanusVR does, but the application will tell you when a new version is available. Simply re-build the package when this happens.
Leap Motion support
The Leap Motion allows you to be more expressive with gesture input, seen by other people within the world. You will want to mount your Leap to the front of your HMD and ensure that you are using the default avatar.
