Where did you get this idea?

I didn’t knew about Microsoft taking over the fsf either, and I am getting concerned about the real freedom behind my beloved Linux.

I think you are confusing FSF with the Linux Foundation, and you can see MS as part of the platinum LF members. Was that it, or you really meant FSF?

If you have installed wlroots, that’s why. Wlroots has a hard dependency on libseatd, which is provided by seatd. Labwc also directly depends on it. Sway as well can use seatd as both documented by sway itself, and its arch wiki, but for some reason it doesn’t directly depend on it, though it depends on wlroots, :). This is not a problem on arch since the seatd service can co-exist with logind/systemd, and on arch you can use the seatd service combined with libseatd for software build on top of libseatd, and users on arch can then choose between seatd or policy kit on that software. On other non systemd distros like artix, the seatd daemon is in conflict with logind (on artix it’s extracted from systemd), precisely because you can get away without logind as long as you use acpid to provide some of the functionality logind also provides besides session administration. Not sure if besides wlroots on archthere’s additional software depending on seatd. Several wayland compositors are based on wlroots, which attempts to somehow offer a standard for compositor and applications developers.

So it might be xdg-desktop-portal behaves differently for sandboxed apps such as flatpak ones than regular apps, hmm. So I’d still like to know how required d-bus is…

Thanks a lot !

Hey, sorry to take adantage of your answer, perhaps you can help me out though.

Is dbus actually necessary for xdg-desktop-portal? I understand from this flatpak post that xdg-desktop-portal is actually a bunch of d-bus interconnections, which of course make d-bus fundamental for xdg-desktop-portal, but wanted to confirm. xdg-desktop-portal is a must on wayland if one wants to share screen through webrtc, or electron apps like slack or teams-for-linux (probably zoom which is Qt as well). But I’ve read some people (this for example) start sway from console without d-bus, without logind/systemd, just seatd on the background (wlroots and sway support seatd). So perhaps those people are not interested on sharing screen, I don’t know. Or perhaps such d-bus plumbing is only required for flatpaks apps, which are sandboxed, thus requiring all that interconnection to access resources and such, and then I’m not sure about a thing…

Thanks !
