Latest nixpkgs-wayland breaks GLX on wayland

[dmayle]

I use nixpgs-wayland with the nvidia driver, and that ensures that my experience under sway is flicker free.

Sometime over the last month, GLX stopped working. If I remove the nixpkgs-wayland overlay, I get GLX working again (but now with all of the flickering).

With the nixpkgs-wayland overlay, EGL and Vulkan work just fine, but GLX fails to load hardware (mesa only)

You should bisect and report the issue to the offending projects repo

Okay, I'm working to do that now. Previous revision 511bd3364d5bab789093d774c7c276d9b7e51011 is good, while revision 791da42b6442870964b11ea28cf5932a76483548 is no longer working:

The offending commit is 298b728f5bb64eca3a57e7767cc649cfecf308fb, which is responsible for updating sway-unwrapped.

Previously, sway was at revision fa294a9094b673e99e5de0c456dc5a6b9ff7db55 from January 2nd.

This commit brings sway up to revision ae33f4eb37a8ee647907e4fef72c6a488b8b1138 from January 19th

That's exactly the issue. It looks like good progress is being made on fixing the issues. I'm freezing my nixpkgs-wayland for the moment until all of the various broken pieces get picked up (XWayland, libva, and sway)

[Artturin]

You can launch sway with -Dlegacy-wl-drm

[dmayle]

Is that a runtime flag, or a compile-time flag?

That is a runtime flag! Once the new sway hits nixpgs-wayland (if it hasn't already), I'll give it a shot.

[colemickens]

Merged last week, I'd expect it to be there. Let us know. This is probably why I've had to run Steam under gamescope.

[Artturin]

Mpv was segfaulting for me and that flag fixed it
