After a few hours of working on all the gotchyas I encountered, I think I'm finally at a spot to comfortably game on my NixOS machine. These components all together made the setup full of a bunch of little papercuts: - Nvidia GPU (5070 Ti) - Completely headless gaming setup powered by Sunshine and Moonlight - Autologin with KDE But, here's the NixOS configuration I came up with for Sunshine + KDE autologin: - https://github.com/heywoodlh/nixos-configs/blob/master/nixos/roles/gaming/sunshine.nix And NixOS configuration for Nvidia-Patch (drastically improves performance for Linux+Nvidia for streaming): - https://github.com/heywoodlh/nixos-configs/blob/master/nixos/roles/gaming/nvidia-patch.nix - Powered by: https://github.com/icewind1991/nvidia-patch-nixos An example of one of the multiple gotchyas I encountered: - On sleep, monitor gets removed on X11 with Nvidia: https://bugs.kde.org/show_bug.cgi?id=460341 - (Causes Sunshine to be unable to stream)
