From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Differences between Wayland and X11 (lemmy.ml)

I stumbled upon this post regarding an earlier rant about wayland, but now it seems fine, according to the author.

After using Linux for nearly 5 years, using both depending on distros defaults, I have to admit that I never got the core/main/game changing differences between wayland and x11.

To be said, that I also dont do fancy linux things other than basic sysadmin stuff and from time to time repair the mess my curiosity left behind.

Could somebody explain the differences between those two and afterwards maybe also say some words about what this has to do with the difference between window managers and desktop environments?

I am also happy about links to good blog posts or stuff, that target this very questions (as long as the questions make sence of course). Thanks beforehand :)

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 !

Looks like XDG Desktop Portal is using dbus and expects it: https://flatpak.github.io/xdg-desktop-portal/docs/common-conventions.html

XDG Desktop Portal uses D-Bus in a slightly uncommon way, due to the potentially long-running nature of some of its requests.

And for the one user in your link https://snoo.habedieeh.re/r/voidlinux/comments/1471jbk/why_do_i_need_to_start_sway_with_dbusrunsession/jnxpxz7/?context=3#jnxpxz7 stating instead using d-bus, would use seatd, I assume it has compatibility with d-bus. He recommends to uninstall d-bus in that case. I have no idea what seatd can do and if this is applicable to other distributions than Void Linux. So unfortunately I don't know more than you. It makes sense that some sort of messaging is required in sandboxed environments.

Funny enough I just looked in my Archlinux based system and look what we have, seatd is installed already. And dbus is also installed.
