@sxpert @drewdevault I presume that if someone really wanted to put in the work, they could create a new stand-alone X server based on the modern KMS/DRM graphics stack, the same one used by Wayland compositors, using Xorg code as a starting point. I think it would be much less work, though, to write a script that starts cage and Xwayland. Then you could invoke that script as if it were a good old X server.
