 codebam | okay, cool | 19:38:38 |
 K900 | You can systemd.user.services.steamos-manager.enable = false for now | 19:38:50 |
| K900 | If you don't mind TDP controls and such not working | 19:38:55 |
| K900 | (or if you're not on a Steam Deck, in which case it probably won't work anyway) | 19:39:22 |
| codebam | oh yeah sorry forgot to answer. it is a steam deck yes, oled model | 19:40:06 |
| codebam | okay I'll probably just deal with it and use suspend | 19:40:34 |
| codebam | anyways, here's the config:
jovian = {
steam = {
enable = true;
user = "codebam";
autoStart = true;
desktopSession = "plasma";
};
devices = {
steamdeck = {
enable = true;
autoUpdate = true;
enableControllerUdevRules = true;
enableSoundSupport = true;
enablePerfControlUdevRules = true;
enableOsFanControl = true;
enableDefaultStage1Modules = true;
enableFwupdBiosUpdates = true;
enableGyroDsuService = true;
};
};
hardware = {
amd = {
gpu = {
enableBacklightControl = true;
enableEarlyModesetting = true;
};
};
};
steamos = {
useSteamOSConfig = true;
};
};

| codebam | https://github.com/Jovian-Experiments/Jovian-NixOS/issues/496
is it because I'm on linux_testing? | 19:44:04 |
| codebam | * https://github.com/Jovian-Experiments/Jovian-NixOS/issues/496
is it because I'm on linuxPackages_testing? | 19:44:20 |
|  @rhapsodos:tedomum.net joined the room. | 19:50:21 |
| K900 | Yes | 19:54:39 |
| K900 | And you can disable all of those options | 19:54:44 |
| K900 | We should document this better | 19:54:49 |
| K900 | But basically all you need is devices.steamdeck.enable | 19:54:57 |
| K900 | Everything else will be pulled in automatically | 19:55:12 |
| K900 | They're internal opt-out knobs | 19:55:15 |
| codebam | ah okay | 19:55:45 |
| codebam | so I unset the kernel like you said to do in that issue, but the values conflict in modules, so how do I resolve that?
error: The option `boot.kernelPackages' is defined multiple times while it's expected to be unique.
Definition values:
- In `/nix/store/b15p9l85pzy934qvdxvq149wm2771dy8-source/modules/devices/steamdeck/kernel.nix'
- In `/nix/store/h6f2qc39h0nkjyfrivi1y9gk9sbyhzf6-source/nixos/modules/tasks/filesystems/bcachefs.nix'
Use `lib.mkForce value` or `lib.mkDefault value` to change the priority on any of these definitions.
| 19:57:24 |
| K900 | Uhh what | 19:57:56 |
| K900 | Oh god bcachefs | 19:57:59 |
| K900 | Yeah you can't do bcachefs on Valve kernel | 19:58:05 |
| K900 | It doesn't have it | 19:58:07 |
| codebam | ah okay I see | 19:58:11 |
| K900 | Also it will probably explode in funny ways with casefolding | 19:58:27 |
| K900 | But that's more of a general casefolding problem | 19:58:34 |
 Alison Jenkins | Does anyone have a better solution than setting LD_PRELOAD="" in the steam game command line to stop the stuttering issue that Gamescope gets under NixOS? It has an annoying side effect of breaking Steam Input. | 19:58:49 |
| K900 | Oh and it will definitely explode with ino64 if you're planning on running 32-bit games | 19:58:51 |
| K900 | I think this is fixed in latest gamescope | 19:59:01 |
| codebam | so I should use... btrfs? | 19:59:05 |
