I did a bit more rebooting just for testing and I also encountered the same problem with the previous image:
● ostree-image-signed:docker://ghcr.io/ublue-os/bluefin:latest
Digest: sha256:be6ec9f7b9940fdd1ecdb9c15a35fc2b67a61b60995c794c47ae7aab11c0a220
Version: 40.20240503.0 (2024-05-03T16:50:25Z)
So it’s not a completely fresh problem.
Edit: I disabled autologin and the login prompt from GDM shows up. Everything looks fine. I can even switch to a TTY via ctrl+alt+F3. But after I enter the right credentials, Gnome sometimes doesn’t start up. I’m using the zsh at the moment and I wonder if this has something to do with this: Double-extra s*rewed: Can't login with GUI or TTY, can't rebase, can't change shell
