@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)I think https://github.com/NixOS/nixpkgs/pull/411574 should fix everything00:05:08
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)(I mean, everything broken by the rename, not like, everything related to CUDA)00:05:27

@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)Okay work was very busy so I didn’t get a chance to review your changes since last week to the db PR Serge, apologies03:53:28

@little_dude:matrix.orglittle_dude So fwiw setting hardware.nvidia.open = false; fixed the issue. 14:32:37

@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)Got halfway through reviewing your PR today Serge, hopefully I can knock the rest out tomorrow if work's not too busy07:58:13
