synergy-core VS deskreen

No one has mentioned ShareMouse yet? (https://www.sharemouse.com/) In my experience it has worked way better than Synergy. I switched after getting fed up with the synergy developers not responding to various multi-year old bugs that made the software unworkable for me (e.g. https://github.com/symless/synergy-core/issues/5992).

The only downside is that you have to "renew maintenance" to continue receiving updates to ShareMouse after a year. But I haven't done that yet and it still works fine for me.

I want to be able to do things like Synergy, Steam Link, Unified Remote, and Media Servers between any of these devices, with as little added latency as possible (especially important for steam link)

i've got several fedora linux machines running and sharing their monitors via synergy (https://symless.com/synergy) , all controlled by the keyboard/mouse on the primary synergy server.

Not sure if this is what you're asking, but I've been using Synergy Pro (Windows, macOS, Linux) for years, and it works seamlessly. It lets you share your mouse and keyboard across multiple systems (with or w/o encryption), copy and paste between computers, etc.

I've got an M2 MacBook Air

Per the Advanced... screen under Displays in System Settings, you can link to a Mac or iPad to control it a la Synergy[0]

I have not done it myself, but I do not see why you could not do it with a current-gen Mac Mini

I previously used a software solution to do the same thing and it was actually really good, better even. It might have been this software but I have to check to be sure - https://symless.com/synergy - as I’m not at my laptop right now.

Or if you are an experienced user of your operating system, you can find solutions on how to create a virtual display without a need for Virtual Display Adapter in the following link: https://github.com/pavlobu/deskreen/discussions/86

Use a vnc client on your android device and setup a virtual monitor on your desktop that is really a vnc server.

I know how to do that with Sway and swayvnc on wayland, as well as with xorg.

This is particularly helpful to people using asahi linux and wanting to connect an external monitor. That can be done with something as simple as a raspberry pi.

EDIT: apparently this project help achieving the same thing on different OS but using webRTC and a browser:

Screen sharing apps are good for this. You can access your pc from your phones browser and local pc IP. https://github.com/pavlobu/deskreen is free one i use.

No it is not necessary. The screen mirroring and sharing single application window functionality of Deskreen are working without any need for Virtual Display Adapter. The Virtual Display Plug is needed only if you want to extend your computer desktop to have a full secondary screen experience with Deskreen.

I use Deskreen with Windows, it has a Linux version that probably works similarly. I think it leverages browser streaming tech.

Easiest way to get it working is with a dummy plug, but maybe there's more options on Linux to fake a display in software.
