Rooms have a homeserver as far as I was aware and stuff goes through that?

I don't fully understand this task. What do you mean with "rooms that are still on :matrix.org?" Matrix rooms aren't "on a server", they are shared by all rooms participating in it and there isn't a central authority.

KDBus single instance API in every single application

I can not, seems fixed.

As for the unnecessary window decorations like the close button, they can be hidden with a 000-gschema.override file. See postmarketOS packaging to see how it's done.

I tested this patch as a fix for https://bugs.kde.org/show_bug.cgi?id=411517 and it did the trick, it doesn't crash anymore.

@graesslin I'm not sure about compiling twice with different settings, but there is most definitely a use-case for this patch: mobile distros.

I have been working on Plasma Mobile packaging for postmarketOS.

@PureTryOut, after following your instructions, this what I get when running the virtual machine:

What am I doing wrong?

For completeness repeating what was said on Telegram, yes that installation guide will do. We also have https://wiki.postmarketos.org/wiki/Plasma_Mobile for Plasma Mobile specific, but the former will do nicely. I assume most people understand they need to choose "plasma-mobile" when promped for a UI choice.

We at postmarketOS already provide a relatively straight forward to use a Qemu VM with Plasma Mobile.

Note that we have already packaged Plasma Mobile for postmarketOS. This already made it possible to run Plasma on whole bunch of new devices (in this list basically every device with a working screen). Besides making it really easy to install it on your phone (as long as it's supported), it also makes Plasma Mobile a "apk add postmarketos-ui-plasma-mobile" away from a regular Alpine Linux installation if our repo is being used. Obviously not many people use Alpine on their computers, but it's a start. postmarketOS also provides a relatively straight forward Qemu VM to use.

Could this be updated? Over at Alpine Linux and postmarketOS we'd love to use this patch as we don't have systemd (but do have consolekit2), but currently it fails to apply.

Noticed this fix was submitted already https://phabricator.kde.org/D6596
