SwayFX Fails to Run on Ubuntu 24.04

[FelixSchladt]

• Swayfx Version:
  • 0.4

Hi All,

first, thanks for maintaining and providing SwayFx, I really would love to be able to run. I am running Ubuntu 24.04 and compiled swayfx using nix, which worked fine. Unfortunately I am unable to run it and get the following errors:

❯ nix develop .
felsch01@fw-felsch01:~/git/swayfx$ nix run .
00:00:00.003 [wlr] [render/egl.c:209] EGL_EXT_platform_base not supported

00:00:00.003 [sway/server.c:150] Failed to create fx_renderer

This seems to be related to mesa/opengl

Did anyone manage to get it running on ubuntu? Is this a bug or a bad setup? SwayWm from the ubuntu repositories runs just fine on my system.

I would really appreciate any help, greetings Felix :)

You're using nix to run it, right? Does it run without nix?

[FelixSchladt]

Same issue, it does not make a difference wether I run it from inside the nix devshell or in the system env:

❯ swayfx
00:00:00.003 [wlr] [render/egl.c:209] EGL_EXT_platform_base not supported
00:00:00.003 [wlr] [render/egl.c:524] Failed to create EGL context

[ErikReider]

Seems like you're missing a driver? You're rocking an AMD IGPU, so Mesa is fine. I'm guessing that trying to run regular Sway is also a problem? What Mesa drivers do you have installed?

[FelixSchladt]

I am currently using sway from the Ubuntu repositories and it works just fine.

My installed mesa driver is Mesa 24.2.8-1ubuntu1~24.04.1

glxinfo -B

Unfortunately a known nix issue, I should add a bit to the README about it. This happens when the nix version of egl is out of sync with your system's version. NixGL is the solution: https://github.com/nix-community/nixGL

[WillPower3309]

Feel free to reopen or add more info if nixGL doesn't work!

Maybe this would help? https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3612

Thanks for the tip with NixGL, unfortunately this still does not fix the issue for me

At least a new error 🤷

@ErikReider You could try the version from Git--- SwayFX has been rebased off a newer Sway version, 1.10.1.
