 mwoodpatrickmx | I'm having a problem adding quickgui to my NixOS flake its failing with:
[ +5 ms] Failed obtaining PRETTY_NAME for Linux: PathNotFoundException: Cannot open file, path = '/usr/lib/os-release' (OS Error: No such file or directory, errno = 2)
Indeed the path /usr/lib/os-release does not exist on my NixOS install which is running as a WSL-2 distro. Should this file exist any suggestions as to why its missing or best way to debug?

 Sandro 🐧 | There is no /usr/lib on NixOS | 12:55:35 |
| Sandro 🐧 | os-release exists distro wide at /etc/os-release | 12:55:53 |
| mwoodpatrickmx | Running qemu on wsl-2 using:
nix run microvm#graphics neverball
I'm getting the following errors does anyone have any suggestions on how to fix/debug:
[2025-02-08T17:04:33.342691105+00:00 ERROR gpu_display::gpu_display_wl] missing interface linux_dmabuf

 K900 | It's not going to run the way you think | 17:25:32 |
| K900 | Nested virt is not good, especially on WSL | 17:25:42 |
| mwoodpatrickmx | Can you elaborate as to why I have none graphical qemu guests running without issue. | 17:28:18 |

Can you elaborate as to why I have none graphical qemu guests running without issue. Because you're trying to do nested virtualization, that's inherently problematic | 17:35:26 |
| K900 | But also NixOS on WSL doesn't have graphics acceleration working properly half the time | 17:35:39 |

| mwoodpatrickmx | Where can I find the bugs filed against graphics acceleration issues on WSL? | 12:44:25 |
| mwoodpatrickmx | In my NixOS WSL distro the /etc/groups file shows
kvm:x:302
But
ls -l /dev/kvm
crw-rw---- 1 root 104 10, 232 Feb 9 04:14 /dev/kvm
How can I fix this?

Other distros (e.g. Debian) show the correct group id. How can I fix this in NixOs?

It doesn't do that for me | 12:52:01 |
| mwoodpatrickmx | NixOS specific issues I'm not seeing the same graphics issues on other Distributions | 12:53:36 |
| K900 | I don't know if there's a specific issue | 12:54:05 |
| K900 | But fundamentally it's just that Windows provides the Linux side d3d12 drivers | 12:54:28 |
| K900 | And those are dynamically linked | 12:54:39 |
| K900 | And don't work as-is on NixOS | 12:54:44 |
| K900 | Actually I think recent Nvidia should work now? | 12:55:03 |
| K900 | AMD definitely not | 12:55:15 |
| K900 | Intel I don't have | 12:55:23 |
| mwoodpatrickmx | I have Intel currently, hoping to get an NVidia digits system when released. Are there other NVidia systems where you think it might work? | 13:00:24 |
| K900 | I don't think those Nvidia systems can even run Windows/ | 13:01:59 |
| K900 | * I don't think those Nvidia systems can even run Windows? | 13:02:00 |
| K900 | They're aarch64 | 13:02:15 |
| K900 | Also they're likely not going to run NixOS out of the box | 13:02:22 |
| K900 | Because they're completely bespoke and don't have drivers in mainline | 13:02:33 |
