DBUS Issues

Hey,
I have issues with one of my Artix systems (oddly enough, I don't experience the issues on one of the other systems).
Unfortunately, it's one where I also lack the knowledge on how to debug that, so I'm looking forward to learning from you!
Anyways, the gist of the issue is that Apps that somehow rely on dbus start extremely slowly.
Thunar, the dialog to unlock the pass passwords database, pavucontrol, blueman, etc.etc. all start very slowly, they take ~30 secs until they first open.
I'm using lightdm + awesomewm and I start my session from
Code: [Select]
.xinitrc
using
Code: [Select]
exec dbus-launch --sh-syntax awesome
.
Thanks in advance for your help, I'm more than willing to share relevant logs (as soon as I know which ones are relevant...)
Best,
dasnacl

If you use lightdm, how do you start your session from .xinitrc?
It is possible through xinit-xsession, but that is hardly a supported package. It's in AUR.

@OP: If you are using that package, you should try upstream.

Ok, so how do I setup DBUS correctly assuming I don't rely on .xinitrc?
But why are you so sure that this is dbus which causes aforementioned issue? This might be everything from misconfigured X-server up to degrading HDD, DDoSed network interfaces included.

I can't be 100% sure, yes. However, an online search has revealed that this is a common issue and it really seems to only appear for apps that rely on dbus.
To verify this, I've ran thunar with dbus-run-session and noticed the issue immediately:

Code: [Select]

So, the issue seems to have something to do with org.freedesktop.secrets, it blockingly waits to establish that service and I'd like to either remove the timeout duration or fix the warning.
Not sure how to do that, though. The threads over on archlinux's forum have solutions that don't seem to apply on my system, e.g. one user reported uninstalling gcolor3 helps, but I don't have that package installed to begin with.

The problem is here, it lies not in dbus itself, but in programs communicating via dbus. Something wrong with fuse (Filesystem in USErspace), it fails to mount a filesystem.

Do you have the xdg-desktop-portal package installed? Do you use any flatpak applications?

Yes, I do have xdg-desktop-portal installed, a dependency of obs-studio for capturing audio via pipwire.
But, I don't have any flatpak installations.

Sorry for double-posting.
I've removed the package and everything works now, looks like I don't need it for obs anyways.
Thanks again, my system is way more usable and not annoying anymore!
