Steam link so my kids can play remotely on my machine and I can continue to work

[Kaballas]

I am using RDPWrapper to allow more than one user to be signed into my machine at a time, this workd great.

So I have steamlink installed on a laptop for the kids to play, when they connect to my machine all they see is a black screen.

Steam signed in on user account A, I work on user account B.

Has anybody attempted this edge case setup before and got it working?

Further info. When they RDP into the machine and game, I continue working without even realising they are remoting in. This is option B as they do get, in their words, glitches always.

I know steam link has more "advanced" controls so to speak over the latency and image quality, and this would just be the perfect solution.

Library/family share was made so parents can share their game library with their kids.
So that multiple devices with separate accounts can share a library.

Steam needs a game to render on the actual GPU, to a screen believed to be real by the graphics driver. Looks like your RDPWrapper doesn't give a bona-fide, 3D-accelerated drawing surface. Or maybe it really only supports RDP connections and doesn't give two ♥♥♥♥♥ about anything else.

So it's either your option B, or option C that is running the games in and streaming the games from a virtual machine. The folks over @ the streaming forum have been talking about 3D rendering in VMs (and streaming from them) for years. I suggest you check up on the existing material on that. Long story short, you need to either assign one of your GPUs to the VM (if you have more than one, i.e. a card and an on-board one) or partition the one GPU so it can get used by the VM.
