Xbox Cloud Gaming controller not connected or idle

[Kaenargh]

I tried playing some games on Xbox Cloud Gaming in Chrome, Edge, Firefox but none of them recognized the built in controller. Anyone got this working yet?

for chrome the changes are pending and for now you had to map keyboard and mouse for it to work.

You could try running the chrome flatpak from a terminal window with the command

flatpak override --filesystem=/run/udev:ro com.google.Chrome

Alternatively you could grant the filesystem access using flatseal[flathub.org] (under "Other FIles[askubuntu.com]" in the filesystem section for the web browser flatpak).

The same workaround is documented here for Edge[github.com]

However that's an unsupported hack - it relies on the version of libudev used when the web browser was compiled for the flatpak matching the version in the SteamOS base system, as there is no guarantee of compatibility between versions (see here[github.com]). If they don't match it might work, but isn't supported and could break (possibly causing a crash) at any time after an update of either SteamOS or the web browser flatpak.

Seems that Microsoft has posted a support article describing how you can setup the Edge browser for Cloud Gaming on Steam Deck. My issue is resolved.
