This repo contains a collection of tools to enable virtual desktop environments for gaming and productivity on Linux using supported XR glasses.
There are two installations at the moment. Note: Don't manually install either of these if you're running the Decky plugin on the same machine, as they invalidate each other's installations. This is only temporary.
- Breezy GNOME for desktop support, primarily in GNOME Linux desktop environments
- Breezy Vulkan primarily for gaming but would work with pretty much any application that uses Vulkan rendering.
Breezy GNOME is a virtual workspace solution for Linux desktops that use the GNOME desktop environment (support GNOME versions 42 through 47); see non-GNOME setup if you want to try it without a GNOME desktop environment. It currently supports one widescreen virtual monitor and multiple physical monitors. See upcoming features for more improvements on the horizon.
For the best performance, ensure you have the latest graphics drivers installed for your distro. Also, double-check that your glasses are extending your workspace and not just mirroring your primary monitor by opening up the Displays settings dialog and choosing the Join option for multiple displays.
Breezy GNOME is in AUR (but not pacman, yet). To install, run these commands from a terminal:
- If you've previously installed Breezy GNOME using the setup script, you must uninstall it first with
breezy_gnome_uninstall yay -S breezy-desktop-gnome-gitsystemctl --user enable --now xr-driver.service- Log out and back in, then proceed to usage.
- Download the Breezy GNOME setup script and set the execute flag (e.g. from the terminal:
chmod +x ~/Downloads/breezy_gnome_setup) - Run the setup script:
~/Downloads/breezy_gnome_setup - Log out and back in, then proceed to usage.
Steam Deck's desktop mode runs KDE Plasma, so, for now, Breezy Desktop can only be run by launching a nested GNOME shell, and requires the read-only file system to be disabled to get setup. If you're interested, and willing to accept any risks that come with disabling the read-only file system, check out the wiki entry.
A workable solution (with some QoL improvements needed) is to use your preferred desktop environment with a GNOME window open in nested mode. To do this:
- Install
gnome-shellusing your distros package manager (e.g. apt-get, pacman, dnf, etc...). This will currently only work with GNOME Shell versions 42-47, so check that usinggnome-shell --version - Run the GNOME setup steps. You shouldn't need to log out and back in since GNOME will be running nested.
- Launch the nested GNOME Shell using
MUTTER_DEBUG_DUMMY_MODE_SPECS="1920x1080@60" dbus-run-session -- gnome-shell --nested
After setup, you'll have an application called Breezy Desktop installed. Launch that and follow any instructions. You will need to log out and back in at least once to get the GNOME extension working. You can also configure keyboard shortcuts for the most common toggle actions. The Breezy Desktop app doesn't have to be running to use the virtual desktop or the keyboard shortcuts once you've configured everything to your liking.
For a double-wide screen, enable "widescreen mode" using the toggle in the Breezy Desktop application. Note: this can be significantly more resource intensive than non-widescreen, you may notice performance dips on older hardware.
- Port to KWin Effect (KDE Plasma support)
- Multiple virtual monitors + multiple physical monitors
- Supported nested or AppImage style deployment. QoL improvements:
- clipboard support
- snapping to proper monitor
- hide window chrome/title bar
Breezy GNOME comes with 2 free trial months. After that, it requires an active Productivity Tier license. Payments are currently only accepted via Ko-fi. Here's the pricing structure:
| Payment period | Price | Upgrade window * |
|---|---|---|
| Monthly | $5 USD, recurring | Within 7 days to upgrade to yearly |
| Yearly | $50 USD, recurring | Within 90 days to upgrade to lifetime |
| Lifetime | $125 USD, one-time | — |
* If you pay for a plan and decide to upgrade to a longer-term plan, you may pay the difference within this window.
If you have enough funds, your license will renew automatically within 7 days of expiration so you never experience an unexpected outage. Your device is never required to be online to continue using Productivity Tier features when enabled, but if your access expires while offline (even if you have enough funds), the features will be disabled until the next time your device goes online and the license can be refreshed. Be sure to check for expiration warnings prior to travel.
To make Breezy widely accessible, Productivity Tier is currently free of charge for qualified individuals using it for non-commercial purposes. Eligible groups include:
- Students
- Public school educators
- Active duty service members and veterans of the U.S. Armed Forces
- Individuals experiencing financial hardship or special circumstances that make electronic payments prohibitive
- Individuals affected by active war zones or humanitarian crises (e.g. Ukrainian citizens)
If you believe you qualify, please email [email protected]. You may be asked to provide documentation to verify your eligibility.
After your first payment, you should immediately receive an email (to your Ko-fi email address) with a verification token. Once you receive that, enter it in the License Details view of the Breezy Desktop application, available from the menu in the top window bar.
If you don't receive a token, you can request one in the License Details view by entering your email address.
For Steam Deck users, the driver is now available via the Decky plugin loader. Just search "xr" in the Decky store to install and use without leaving Gaming Mode. You can now enable or disable the driver and manage other driver settings via the Decky sidebar menu.
You may still opt to do a manual installation using the instructions below if you enter Desktop Mode.
- Download the setup script and set the execute flag (e.g. from the terminal:
chmod +x ~/Downloads/breezy_vulkan_setup) - Run the setup script as root (e.g.
sudo ~/Downloads/breezy_vulkan_setup) - If you're not on Steam Deck, you'll need to set the
ENABLE_VKBASALTenvironment variable to1. You'll either need to set this globally to enable it for all games, or set it as a launch option for individual games (e.g. in Steam's Launch Options fieldENABLE_VKBASALT=1 %command%).
See XRLinuxDriver's supported devices.
Once installed, you'll want to make sure you've enabled the driver (xr_driver_cli -e) and then you can go into whichever output mode you'd like using (xr_driver_cli -m) where -m is for mouse mode, -j for joystick, -vd for virtual display, and -sv for sideview; note that these two commands can't be combined, they have to be done separately. From there, you should be able to launch any Vulkan game, plug in your glasses (at any point, not just after launching), and see a floating virtual display or a sideview screen (depending on which mode you've chosen).
There's a wait period of 15 seconds after plugging in XREAL glasses where the screen will stay static to allow for the glasses to calibrate. Once ready, the screen will anchor to the space where you are looking.
To see all the configuration options available to you, type xr_driver_cli with no parameters to get the usage statement. There are some things you can't trigger from the script, like re-centering the virtual display or entering SBS mode; you can achieve these things through multi-tap or through the physical buttons on the glasses, respectively.
I've implemented an experimental multi-tap detection feature for screen re-centering (2 taps) and re-calibrating the device (3 taps). To perform a multi-tap, you'll want to give decent taps on the top of the glasses. I tend to do this on the corner, right on top of the hinge. It should be a firm, sharp tap, and wait just a split second to do the second tap, as it needs to detect a slight pause in between (but it also shouldn't take more than a half a second between taps so don't wait too long).
Breezy Vulkan's Supporter Tier features are enhancments to core functionality, offered as a way to reward those who have supported the project. Core features -- like Virtual Display mode, VR-Lite mouse/joystick modes, and Follow mode's display positioning/resizing settings -- will always remain available to everyone regardless of supporter status. Here's the pricing structure:
| Payment period | Price | Upgrade window * |
|---|---|---|
| Yearly | $10 USD, recurring | Within 90 days to upgrade to lifetime |
| Lifetime | $25 USD, one-time | — |
* If you pay for a plan and decide to upgrade to a longer-term plan, you may pay the difference within this window.
If you have enough funds, your access will renew automatically within 7 days of expiration so you never experience an unexpected outage. Your device is never required to be online to continue using Supporter Tier features when enabled, but if your access expires while offline (even if you have enough funds), the features will be disabled until the next time your device goes online and the license can be refreshed. Be sure to check for expiration warnings prior to travel.
Features currently offered:
- Smooth Follow (in Follow mode)
- Automatic Recentering (in Virtual Display mode)
- Side-by-side support (in Virtual Display mode)
If you donate at least $10, you should immediately receive an email (to your Ko-fi email address) with a verification token. If you don't, request it using the config script:
xr_driver_cli --request-token [emailAddress]Once you have a token, verify it using:
xr_driver_cli --verify-token [token]
xr_driver_cli --refresh-licenseTo disable the floating screen effect, either disable the driver (xr_driver_cli -d), unplug the glasses, or hit the Home key (you'll need to bind this to your controller, if on Steam Deck).
Rerun the breezy_vulkan_setup script. No need to re-download this script, as it will automatically download the latest installation binary for you.
If you wish to completely remove the installation:
- For Breezy GNOME:
- If you installed via the setup script run the following:
~/.local/bin/breezy_gnome_uninstall - If you installed via
yayrun the following:pacman -R breezy-desktop-gnome-git, you may also want to uninstall the base driver withpacman -R xr-driver-breezy-gnome-git
- If you installed via the setup script run the following:
- For Breezy Vulkan run the following:
~/.local/bin/breezy_vulkan_uninstall. This won't uninstall the base driver package, follow the instructions at the end of the uninstallation to do this manually.
Your right to privacy and the protection of your personal data are baked into every decision around how your personal data is collected, handled and stored. Your personal data will never be shared, sold, or distributed in any form.
In order to provide you with Supporter Tier features, this application and its backend services have to collect the following pieces of personal information:
- Your email address is sent to this application's backend server from either the payment vendor (Ko-fi) or from your device (at your request). Your email address may be used immediately upon receipt in its unaltered form to send you a transactional email, but it is then hashed prior to storage. The unaltered form of your email address is never stored and can no longer be referenced. The hashed value is stored for later reference.
- Other personal data may be sent from the payment vendor, but is never utilized nor stored.
- Your device's MAC address is hashed on your device. It never leaves your device in its original, unaltered form. The hashed value is sent to this application's backend server and stored for later reference, and -- up to version 0.8.7 -- to Google Analytics.
Hashing functions are a one-way process that serve to anonymize your personal data by irreversibly changing them. Once hashed, they can never be unhashed or traced back to their original values.
