Kinoite: broken Setup, only "startx" working, no sddm, no Wayland

I need help troubleshooting this install.
It was some while ago, installing it

Hardware: Acer Swift 5, AMD Ryzen, weird hardware but should work
OS: Former Fedora Kinoite 37, now Ublue 38 (verified ISO after rebasing to unverified)

Its really weird and currently I cant find the reasons.

  • the user has regular groups and permissions, like mine on my regular machine.
uid=1000(user) gid=1000(user) Gruppen=1000(user),10(wheel) Kontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

First Problem: rpm-ostree permissions

But I cant do rpm-ostree update as it has no permission. The /usr/share/polkit-1/rules.d/org.projectatomic.rpmostree1.rules looks vanilla though.

The only overrides in /etc/polkit-1/rules.d/ are one for udisks mount and for udisks LUKS unlock, which I have on my machine too.

Second Problem: flatpak permissions

Also the wheel user cant update flatpaks but gets this weird error:

Warning: Failed to get revokefs-fuse socket from system-helper: Flatpak system operation GetRevokefsFd not allowed for user
Warning: Flatpak system operation Deploy not allowed for user

After doing (manually!)

groupadd flatpak
sudo usermod -aG flatpak user

I can now update Flatpak seemingly, but it crashes anyways with the error

Warning: Flatpak system operation Uninstall not allwed for user

It was like this by default afaik, this is the weird thing. I install all my Flatpak apps as system apps on my main machine too, to have them in all users.

Doing both actions with sudo works, but afaik this breaks Discover and more apps.

Third Problem: No SDDM or Wayland

This is crazy too. I upgraded my entire system, but still I get a blackscreen when SDDM should show. So I press Ctrl+F4 to get into TTY.

startx works from here, startplasma-wayland or sudo sddm both result in total freeze and nothing showing.

I am currently backing up the home and reinstalling the system, but this is pretty worrying and I would really prefer to fix this system, especially as it should be rather easy.

It should not be the case, but X11 saves my day here, as I can use Syncthingy Flatpak to sync the data. This would not be possible on Wayland.
