Xvfb (virtual framebuffer X server)

Xvfb, the X virtual framebuffer server, rebuilt from source for rootless jailbreaks. It runs a full X11 server with no real display hardware, drawing everything into an off-screen image in memory.

It's the engine behind the native Xios iOS app: Xvfb draws into a shared image that the app puts on screen, and touch and keyboard input are passed back into X11.

Stock X servers crash on launch under rootless because they expect a system shell at `/bin/sh`, which isn't present (it lives at `/var/jb/bin/sh`). This build uses the right path, so the keyboard sets up correctly.

• The same Xvfb from xorg-server 1.20.11, built from source
• Installs cleanly and registers `/var/jb/usr/bin/Xvfb`
• Pair with a window manager (`fluxbox`), `xterm`, and the `x11-fonts-sf` package

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