Description Alexander Scheel 2021-06-07 20:29:04 UTC 
Description of problem:

After logging out from an existing session, logging in again as the same user causes gnome-shell to crash. This does not happen on clean reboot, but restarting gdm (sudo systemctl restart gdm) isn't sufficient to fix this.

Removing the file mentioned below (/tmp/.X11-unix and restarting gdm does work though).

(Implying this path got created not by systemd-tmpfiles-setup but by gnome-shell running as user gdm).

This means the owner/group-owner is wrong on this file, which I can confirm by manually looking at it. Changing the owner back to root:root does indeed fix this problem.
