google-trogdor: Gnome fails to load after upgrading to postmarketos-base-32-r0

Describe your issue

What's the expected behaviour?

The device boots into the Gnome login screen

What's the current behaviour?

The console login screen appears briefly (this seems new) and after 1 or 2 seconds, a blinking cursor appears. After some more seconds it stops to blink and that's it.

One can use ttyescape to get back to a virtual terminal.

During the short period where the console login screen is shown there is an opportunity to switch to another TTY using Alt+Arrow-right before one gets stuck on the failing Gnome session.

How to reproduce your issue?

$ sudo apk upgrade -avvs
(1/4) Upgrading postmarketos-base-nofde (31-r1 -> 32-r0)
(2/4) Upgrading postmarketos-base (31-r1 -> 32-r0)
(3/4) Upgrading postmarketos-base-mesa (31-r1 -> 32-r0)
(4/4) Upgrading postmarketos-base-nftables (31-r1 -> 32-r0)
OK: 976 packages, 3527 dirs, 63516 files, 3869 MiB

Then reboot

What device are you using?

google-trogdor (Wormdingler variant)

On what postmarketOS version did you encounter the issue?

edge (master branch)
v23.12
v23.06 (supported until 2024-01-18)
I confirm that the issue still is present after running sudo apk upgrade -a

On what environment did you encounter the issue?

Environments

How did you get postmarketOS image?

from https://images.postmarketos.org
I built it using pmbootstrap
It was preinstalled on my device

What's the build date of the image? (in yyyy-mm-dd format)

Additional information

Here is a logfile from /var/log/gdm/greeter.log: greeter_32-r0.log

On IRC it was suggested to set permissions on the X11-related files in /tmp. Doing sudo chmod -R a+rwx /tmp/.X1* and then sudo rc-service gdm restart indeed improves the situation: the login screen appears, but logging in fails. Maybe I was missing /tmp/.ICE-unix. This second logfile is from that situation. greeter_32-r0_777.log

I think the ownership of /tmp/.{X11,ICE}-unix was changed from root:root to gdm:gdm?

Ah, could it have something to do with 1229616e?

Plasma Mobile doesn't seem to be affected, I did a quick test with pmbootstrap install on an SD card
