NVIDIA already has been offering GeForce NOW for Valve's Steam Deck while now they are offering it as a Flatpak build for the typical Linux desktop. At launch the Flatpak build is also just for x86_64 Linux with no AArch64 Linux builds or similar at this time. If you are using NVIDIA graphics the NVIDIA R580 series or newer is recommended while using the X.Org session. While the native GeForce NOW application for Linux is built as a Flatpak, NVIDIA is not going to be distributing it via Flathub. Those wanting to initially download GeForce NOW for Linux will be able to access the Flatpak via NVIDIA.com beginning today.
