Hi there, arkenoi,
I’ll look more into Liteqube after reading this! I was daydreaming of a dom0 supporting VR by having X windows supported in VR. I think this dynamic xorg attacher is an elegant solution since X windows may not be the only kind of GUI process spawned for a lightweight hypervising server. I’m not sure but I’m still investigating VR processes like what I describe. Could this methodology work for Windows-compatible Qubes systems, too? (not to add more to our plate, happy developers, happy developers!!)
