Just to note the best VNC client to use, whether you are on Windows, Mac or Linux is RealVNC imo. You may need to disable some remapping that RealVNC attempts to do under macOS & also disable the local cursor under all OS's when using RealVNC. UltraVNC is fast and interesting, but ultimately I felt RealVNC did a better job overall and is cross platform.

Can't really think of anything else to note here. Of course it is best to tunnel your correction or use secure means of using VNC. This solution appears to work surprisingly well over all.

Other things to note I guess is that under Virtualization of Vmware workstation vs HyperV.. HyperV appears to perform better, but I need to do more extensive tests and make sure it wasn't HyperV that caused the slow downs for Vmware in the first place. Either way it is very positive to see it perform well with a virtualization solution like HyperV imo, it is not preferred and usually due to a lack of performance, but responsiveness has been very good.

Oh other thing to note about HyperV is that your keyboard inputs event id will often change.. so on the server end if you create a service you may be best off querying and parsing the event id on each boot. I will follow this up later with more info.

Reading online some Linux DEs or compositors like Marco might be better off disabled while using VNC? I am not sure, I have not tried that, and I tend to use Budgie any ways, so not a DE that uses Marco any ways (Mate, xfce, etc).

On macOS Jump Desktop is actually better than RealVNC - Jump Desktop is the only one that will allow you to go full screen without creating a new Space (edit in preferences). This makes it easier to switch to apps in your dock vs being kicked out of your "Space" as fullscreen apps often don't allow other apps to overlay on top of your fullscreen app.

I've gotten almost everything to work, except for the x11vnc that ist redirecting my input.
At first it said that /root/.XAuthoritiy didn't exist, so I touched it, but now it still fails. Any idea why?

Setup: macOS via Jump Desktop (latest, respectively) using RDP to Ubuntu 22.04 with xrdp.
