sway does not start with EGL_NOT_INITIALIZED error

[lunik1]

Describe the bug

When trying to launch sway (from tty) I get the error

libEGL warning: MESA-LOADER: failed to open : /run/opengl-driver/lib/dri/_dri.so: cannot open shared object file: No such file or directory (search paths /run/opengl-driver/lib/dri)

(It seems strange that sway is trying to use _dri.so)

I'm not completely sure whether this is nixpkgs or home-manager's issue, but it seems to have occurred when bumping nixpkgs from 51bb9f3 to b27eaa1. If I pin nixpkgs at b27eaa1 and just update home-manager sway still runs. I am working on finding the specific commit with the breakage.

To Reproduce
Steps to reproduce the behaviour:

1. Try to launch sway from tty

Expected behavior
Sway should launch

Additional context
I am using home-manager to manage sway, tracking nixpkgs-unstable but my system configuration tracks 21.05. My flake-based config can be found here.

Seems like you're hitting the issues described in #119558 and #120325. Try to make sure to use the same Nixpkgs revisions for NixOS and home-manager, that should fix it. This new limitation should likely also be mentioned in the home-manager documentation for Sway.

Another fix (for sway at least) is to set wayland.windowManager.sway.package to null and then enable the sway module in NixOS. Although form what I understand while this allows sway to work other programs depending on mesa can also break?

Good idea. IMO that's preferable anyway. I once suggested that in nix-community/home-manager#1288 (comment) but I'm not sure if it was ever documented.

Yes, unfortunately (IIRC I also observed this issue with XWayland).

First, thank you very much for spending time on this issue. Second I don't get what you exactly mean 😢

To use e.g 21.05 version for both nixos and home-manage 🤔 ?

Sorry for the noise, I answered my question myself. I switched back from unstable to 21.05 and forgot to switch the sway package back from unstable to normal in my home-manager configuration 🤦 after doing this everything works as expected 😄
