UHF X11

X11 built for VisionOS and Apple Vision Pro.

A modern X11 built for basking in the past. Send your favorite Xlib clients to spatial windows, and live out the future you were promised.

Objective

UHF X11 turns Apple Vision Pro into a full X11 display server.

Attach X clients and vintage machines to send X11 calls into native, pixel-pretty spatial windows in visionOS.

X11 MATERIALIZES IN SPACE.

Specification

Rootless Spatial Windows

Each X11 top-level opens as its own visionOS window. Position them anywhere in your space.

External X11 Clients

Accept connections from trusted machines over standard, native X11 TCP.

Beautiful Pixel Rendering

X framebuffer content is presented at native resolution with nearest-neighbor scaling for small surfaces.

80s-Soaked Display Effects

CRT scanlines, phosphor masks, glow, and vignette presets for classic display character.

MIT-MAGIC-COOKIE-1

X authority cookies are generated on device and copied to client machines for authenticated connections.

Experimental Indirect GLX

3D in 2D in 3D. OpenGL clients can use GLX rendering over X11. Compatibility varies, as it did in the 2000s.

Custom Font Packs

Import bitmap font directories from visionOS folders. Core X11 fonts ship with the app.
