Apollo
Sunshine fork - The easiest way to stream with the native resolution of your client device (by ClassicOldSong)
Project mention: IronRDP: a Rust implementation of Microsoft's RDP protocol | news.ycombinator.com | 2025-03-21> in sunshine/moonlight such as you still have monitor output
Apollo[1] fixes this problem really neatly - there's a "Virtual Desktop" option that adds a virtual desktop, and you can disable all the local monitors while in this session so that a local person doesn't see your desktop while you're remoted into it (just remember to lock after you end your session!).
I believe it also preserves monitor layouts when starting/ending sessions.
I used Sunshine and had a bunch of hacks in the startup/teardown scripts to get the same behavior but it was really brittle. Apollo makes this work out of the box.
