 matthewcroughan | it shows up in wivrn, interacts, no errors, it's just that nothing shows up in the headset running wivrn | 16:56:38 |
| matthewcroughan | gnome believes that screen sharing is taking place however | 16:56:49 |
| matthewcroughan | Ah maybe it's dmabuf related https://github.com/galister/wlx-overlay-s?tab=readme-ov-file#crashes-blank-screens | 16:57:22 |
| matthewcroughan | are nvidia drivers also something that hold the kernel back like zfs? | 17:18:56 |

| matthewcroughan | just so buggy | 17:27:07 |
 K900 | Yes | 17:34:31 |
| K900 | There's no stable kernel API | 17:35:05 |
| K900 | So any out of tree driver can and will break | 17:35:10 |
| matthewcroughan | And there's no way to opt out of the open nvidia driver really anymore | 17:40:00 |
| matthewcroughan | so that's pretty bad | 17:40:03 |
| matthewcroughan | it's like zfs but non-optional | 17:40:35 |
| K900 | There is, you can just run Nouveau | 17:42:10 |
| matthewcroughan | rofl | 17:42:19 |
 olivia | nvk is genuinely pretty good these days if you have a turing+card. If you haven't tried it recently you might be surprised | 19:54:32 |
| olivia | if this thing you're trying to run is cuda only that won't work though | 19:54:39 |
| olivia | * if this thing you're trying to run is cuda-only that won't work though | 19:54:45 |
 ElvishJerricco | I'm guessing nvk is vulkan only, and that that's ok as long as you only play windows / proton games because they're almost universally adapted to vulkan? | 20:13:49 |
| olivia | it's vulkan but mesa 25.1 defaults to zink/nvk for opengl on Turing cards now | 20:32:07 |

nvk is genuinely pretty good these days if you have a turing+card. If you haven't tried it recently you might be surprised Are there any docs on how to set it up? I feel very lost when touching NVIDIA related settings. | 23:18:06 |

| ElvishJerricco | it sounds like if it's anything like amdgpu you just remove any nvidia related code from your config and mesa will do the right thing on its own (as long as you're on a nixpkgs revision with a new enough mesa) | 23:20:06 |
| ElvishJerricco | but I'm only guessing | 23:20:53 |

it sounds like if it's anything like amdgpu you just remove any nvidia related code from your config and mesa will do the right thing on its own (as long as you're on a nixpkgs revision with a new enough mesa) I think it used to be like that so seams reasonable. | 23:21:32 |
| srestegosaurio (on tchncs.de) | And what about nvidia-offload? | 23:22:01 |
| olivia | yeah, this is accurate | 23:22:42 |
| olivia | specifically you'll get zink-by-default if you have https://github.com/NixOS/nixpkgs/pull/399388 (which was merged 12 hours ago) | 23:23:14 |
| olivia | yeah, you'll want to remove that | 23:23:57 |
| ElvishJerricco | I'm guessing it's the same story with nvidia-offload? i.e. Mesa just already knows how to use another GPU for rendering and lets the app choose? | 23:24:21 |
