The logs you posted indicate a core dump, but I don't think you have debugging symbols for xdpw, so that won't help. I have a theory that xdpw is trying to exit gracefully (for one reason or another) but is segfaulting trying to free memory that was never allocated. I created an issue for that already, but it is secondary to your issue and it just means we don't have any nice log messages. Can you share the versions of pipewire, xdg-desktop-portal, and xdg-desktop-portal-wlr that you're using? On arch, the output of I think your real issue (including slow to start GTK apps) is improperly set environment variables. I wrote up an explanation here, but long story short, you should probably do what the sway wiki suggested, but for the XDG_CURRENT_DESKTOP variable. This particular writeup is new, and if it is helpful (or not), I'd appreciate feedback. Let me know how it goes. If you have no luck with tweaking variables or updating packages, we can gather logs from manual runs and possibly get a build with debugging symbols to test. |

Thank for the explanation. Unfortunately, setting the XDG_CURRENT_DESKTOP variable does not help either (in theory it is already correctly set in These are the versions of the installed packages: |
|
Okay, let's try starting xdpw manually. Kill both xdg-desktop-portal and xdg-desktop-portal-wlr and run the following: /usr/lib/xdg-desktop-portal -vr & /usr/lib/xdg-desktop-portal-wlr -l DEBUG 2>&1 | tee xdpw.logThat log should help shed some light on what's going on. |
|
Ok, here is the log: And after that the following started to appear: |
This is your issue. Are you sure pipewire is running? It should start automatically via socket activation, but for debugging, I would recommend ensuring that it is already running. If you can confirm it is, do its logs contain anything of interest? It would have been better if you had run the exact command I shared, which would have increased the log level and given us more information. Also, can you confirm that you killed all existing xdp/xdpw instances first. |
|
Oh, I wrote it by hand and somehow didn't noticed the entire line. Here it is now: Pipewire is definitely not starting. The systemd unit is inactive and if I try to start it manually I get this: I will install the git version and see if that changes anything. Edit: |
You can start pipewire like this for more debugging output. The line mentioned in those pipewire logs is just a generic error handler, so we may need more verbose output.
Edit: Also, even though pipewire is giving that error, is it exiting? I'm assuming it is, but pipewire creates noisy logs. Some errors may not be fatal. |

OK. So I run The two red lines: Edit: The output: |
I can't say at this point why pipewire is failing to start on boot (or, more likely, as a result of socket activation), but starts fine when run manually. That's a pipewire issue (and one that I can't reproduce, as I have an identical setup with no issues). My recommendation might be to try uninstalling and reinstalling pipewire in case some service/socket files have gotten messed up. Also check on any systemd overrides that might be present for pipewire configs. It seems like xdpw is working as expected when pipewire is running though, so I am going to close this issue. As you continue to debug pipewire, if you have other questions I can help with, you can @ mention me in this closed issue, or I usually hang around #sway on freenode. If you try to reach me on IRC, nick mention me (danshick) so I get a notification. |

Thanks for your time @danshick ! I solved the problem! (I gues at least). The systemd units for |

No idea how it would have gotten masked. It definitely shouldn't be. Happy to help and glad it's fixed! |

Interestingly, I'm getting the same issue. It fails because it can't connect to pipewire, but the pipewire services are available: $ systemctl --user status pipewire.service

Hi,
I am running Archlinux with sway and I don't know exactly when this started happening, but xdg-desktop-portal-wlr does not work for me anymore. The following error is shown:
Maybe related: I am also experiencing this problem with GTK apps taking a while to start. However, the solution stated there does not work for me.
