Does Steam Link run on Linux?

Steam Link is on Flathub, published by Valve and marked verified, which means it comes from Valve rather than a third party. It does the same job as the Windows version: connect a controller, pick a computer on your network that is running Steam, and play its games on this machine.

This is useful in two directions during a switch. You can keep the Windows PC in another room as the machine that actually runs the games, and use the Linux laptop as the screen. Or you can point it the other way and stream from a Linux desktop to something smaller.

The limits are the ones streaming always has. Everything goes over your network, so a wired connection or a strong 5GHz signal makes the difference between good and unplayable. There is a small delay, fine for most games and noticeable in fast shooters. Picture quality drops when the network is busy.

Nothing needs migrating. Steam Link holds no games of its own, just the connection to a computer that does.
