 hexa | ok, apparently not | 15:44:08 |

| hexa | * it seems like nvidia_uvm doesn't get loaded at boot anymore | 15:44:31 |

| SomeoneSerge (back on matrix) | Yeah, somehow softdep breaks with the open driver? | 16:03:59 |
| hexa | nope, reformat | 16:03:59 |
| hexa | ok, has been there since 2023.11 | 16:04:16 |
| hexa | and yeah, I'm on the open driver | 16:04:19 |

anyone touch the nvidia driver code? packaging i mean. The long standing bug of "use xrandr twice and you get a segfault in X11" doesn't happen to me anymore apparently

 connor (he/him) | Ah right that thing
I was told CMake is supposed to understand it’s a header-only library and not try to actually link against a shared object file, so not sure why it’s doing exactly that and causing the build to fail | 01:48:43 |
| connor (he/him) | Ah I need to actually respond to the issue after I try their suggestion | 01:50:04 |
| connor (he/him) | How is there so little time in a day 😭 | 01:50:57 |
| connor (he/him) | ugh, my main desktop is gone from my tailscale network and unreachable from the other hosts. Damn Intel chip probably did a voltage whoopsy and needs to be hard reset. | 04:05:37 |
| connor (he/him) | Cool that shit is gonna be broken until I can fly home at the end of the month lmao | 04:42:54 |
 Moritz Sanft | If I'm not mistaken, this brings in a dependency of nvidia-x11 upon all of the packages listed here, right?
https://github.com/NixOS/nixpkgs/blob/eac1633a086e8e109e00ce58c0b47721da1dbdfd/pkgs/os-specific/linux/nvidia-x11/generic.nix#L112
I wondered why perl is included in my closure, and thus discovered the mesa dependency of the driver, then got confused. If this is really the case, this is something you wouldn't want on a space-constrained system, right? | 15:20:27 |

 sielicki | hey connor -- I can't request a github review on https://github.com/aws/aws-ofi-nccl/pull/745 for some reason, but I would like a review from you (or anyone else idling here) if you can find time. It's using the external cuda flake. | 04:07:57 |
| sielicki | I have a very thorough libfabric derivation on my personal laptop that I intend to finish over the holidays and propose to nixpkgs proper | 04:08:36 |
| sielicki | * hey connor -- I can't request a github review on https://github.com/aws/aws-ofi-nccl/pull/745 for some reason, but I would like a review from you (or anyone else idling here) if you can find time. Specifically asking you because it's using your external cuda flake. | 04:09:30 |
| sielicki | want to call it out here (mostly as a reminder to myself): the openmpi drv in nixpkgs should be capable of completely detaching from ucx/ucc, but it's not simple to make that happen today. On aws you shouldn't need ucx/ucc at all. | 04:13:37 |
