Xios (IOSurface X server)

Xios is the native X11 server behind the Xios iOS app, built for the fastest display path. It's xorg-server 1.20.11 (the same source as Xvfb) with a custom backend that draws straight into a GPU-shared image the app shows on screen, with no per-frame copying.

Xios writes a small config file at `/var/jb/tmp/xios.json` so the app picks this fast path automatically, and touch and keyboard input are passed back into X11. If you need the simpler, more portable version instead, install x11-xvfb and use `x11-server.sh`.

• Built from source for rootless, signed to install on device
• Starts cleanly on rootless, with the keyboard set up correctly
• Includes the `xios-server.sh` launcher at `/var/jb/usr/bin/xios-server.sh`
• Pair with a window manager (`fluxbox`), `xterm`, and the `x11-fonts-sf` package

Built for iPadOS/iOS rootless (palera1n/Dopamine, `/var/jb`).
