A lightweight OpenXR/OpenVR overlay for Wayland and X11 desktops, inspired by XSOverlay.
WlxOverlay-S allows you to access your desktop screens while in VR.
Compared to similar software, WlxOverlay-S aims to run alongside your other VR games or experiences and have as little performance impact as possible. The UI looks and rendering methods are kept simple and efficient as much as possible.
This is the coming-together of two of my previous projects:
- WlxOverlay (SteamVR overlay written in C#)
- WlxOverlay-X (OpenXR overlay using StereoKit, written in Rust)
We are available on either:
- Discord: https://discord.gg/gHwJ2vwSWV
- Matrix Space:
#linux-vr-adventures:matrix.org
Questions/issues specific to WlxOverlay-S will be handled in the wlxoverlay chat room.
- Grab the latest AppImage from Releases.
chmod +x WlxOverlay-S-*.AppImage- Start Monado, WiVRn or SteamVR.
- Run the overlay
AUR package is wlx-overlay-s-git.
You may also want to build from source.
If you get a screen share pop-up, check the terminal and select the screens in the order it tells you to.
SteamVR users: WlxOverlay-S will register itself for auto-start, so you will not need to start it every time.
Please continue reading the guide below.
Much of the functionality in WlxOverlay-S depends on what color of laser you are using to interact with a UI element.
Using the default settings, there are 3 modes:
- Regular Mode: Blue laser
- Right-click Mode: Orange laser
- Middle-click Mode: Purple laser
Please see the bindings section below on how to activate these modes.
The guide here uses the colors for ease of getting started.
Check your left wrist for the watch. The watch is your primary tool for controlling the app.
Hovering a pointer over a screen will move the mouse. If there are more than one pointers hovering a screen, the pointer that was last used to click will take precedence.
The click depends on the laser color:
- Blue laser: Left click
- Orange laser: Right click
- Purple laser: Middle click
- Stick up/down: Scroll wheel
To curve screens, grab them with one hand, then with the other hand, hover the laser over the overlay and use the scroll action.
See the bindings section on how to grab, move and resize screens.
The keyboard is fully customizable via the keyboard.yaml file.
Download it into your ~/.config/wlxoverlay/ folder and edit it to your liking.
Typing
- Use the BLUE laser when typing regularly.
- While using ORANGE laser, all keystrokes will have SHIFT applied.
- Purple laser has no effect as of now.
Modifier Keys are sticky. They will remain pressed until you press a non-modifier key, or toggle them off.
If your bindings are not supported, please reach out.
We would like to work with you and include additional bindings.

This seems to only affect SteamVR 2.4.4 (stable as of writing). Try switching to temp_v1.27.5 or beta using the SteamVR beta selection if this bothers you. (The linux-v1.14 branch will not work.)
This is a rare issue that can make your desktop not react to click or keys due to a modifier being stuck somewhere. Restarting the overlay fixes this.
This seems to be an issue specific to Electron apps (Discord, Element, Slack, Spotify) on Wayland. Scrolling will work when using these in your web browser.
- DPI scaling is not supported and may cause the mouse to not follow the laser properly.
- Upright screens are not supported and can cause the mouse to act weirdly.
- Screen changes (connecting / disconnecting a display, resolution changes, etc) are not handled at runtime. Restart the overlay for these to take effect.
