Edit: rootless in this context means the remote windows appear like local windows; not in a big "desktop" window. It's nothing to do with the root account. Sorry, I didn't come up with that confusing term. If anyone can think of a better term let's use that!
This should be a simple task. I ssh to a remote server. I run a GUI command. It appears on my screen (and isn't laggy as hell).
Yet I've never found a solution that really works well in Linux. Here are some that I've tried over the years:
- Remote X: this is just unusably slow, except maybe over a local network.
- VNC: almost as slow as remote X and not rootless.
- NX: IIRC this did perform well but I remember it being a pain to set up and it's proprietary.
- Waypipe: I haven't actually tried this but based on the description it has the right UX. Unfortunately it only works with Wayland native apps and I'm not sure about the performance. Since it's just forwarding Wayland messages, similar to X forwarding, and not e.g. using a video codec I assume it will have similar performance issues (though maybe not as bad?).
I recently discovered wprs which sounds interesting but I haven't tried it.
Does anyone know if there is a good solution to this decades-old apparently unsolved problem?
I literally just want to ssh <server> xeyes and have xeyes (or whatever) appear on my screen, rootless, without lag, without complicated setup. Is that too much to ask?
Yes that's to much to ask
You are adding a ton of overhead and complexity. Expecting it to just work is underestimating the difficulty of it all. With that being said, Xpra is probably what you are looking for. However, I would suggest that you take a look at your use case as there is probably a better solution. What app are you trying to use?
Also, Xorg is a bit of a dinosaur at this point. It isn't going away but gnome and kde have both made plans to drop support long term. We still have a few years but from a longevity perspective I would start thinking about new solutions. KDE and Gnome both support RDP and there are plenty of modern web interfaces for managing servers like Cockpit.
