New x86_64 host for a 4th-gen Core i7 (Haswell) with a GTX 1070 8 GB, wired to a television and driven with a Bluetooth controller. Session: greetd gets an initial_session, so the machine autologins into the gamescope Steam session at boot with no greeter and no keyboard. Quitting Steam falls back to greetd's default_session (ReGreet), where the ordinary Sway session is available for keyboard-and-mouse work. Graphics: the GTX 1070 is Pascal, so it needs driver branch 580 (nvidiaPackages.legacy_580) like the Mac Pro's Quadro P400 -- the nixpkgs default (production, 595.x) dropped Pascal support. Games: RetroArch built through retroarch-bare.wrapper with 17 cores covering NES through PS2, GameCube and Wii; Clone Hero; and Steam with Proton-GE and protontricks. RetroArch's menu toggle is bound to L3+R3, without which there is no way to exit a running core on a machine with no keyboard. Proton prerequisites beyond what programs.steam already arranges: the esync file-descriptor hard limit is raised from systemd's default 524288 to 1048576 (soft limit untouched), and Proton-GE is wired in via extraCompatPackages. vm.max_map_count already defaults high enough in nixpkgs and needs no override. Content lives in a shared /srv/games tree created by systemd.tmpfiles, laid out one directory per system under roms/ using the libretro/ES-DE naming convention, plus bios/, saves/, states/, a Steam library folder and Clone Hero's songs. RetroArch is pointed at it declaratively. hardware-configuration.nix is a placeholder, not a hardware scan: the machine is not installed yet. It assumes partition labels `nixos` and `BOOT` and must be replaced with nixos-generate-config output. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
