[SOLVED] GNOME session manager hangs until terminated at login

Ever since yesterday, I have been unable to log into GNOME. I do not remember changing anything that would have caused gnome's session manager to hang forever.

After some looking into the journal and around the forums, I have not been able to find any error messages related to gnome session manager failing like this.

This happens with both GNOME and GNOME Classic on both X11 and Wayland. Starting other window managers with GDM also works as expected.

$ journalctl -b --user --unit=gnome-session-manager@gnome.service

Re: [SOLVED] GNOME session manager hangs until terminated at login

Turns out that gnome-session trips over large directories in $XDG_DATA_HOME/applications. I had accidentally symlinked a very large directory instead of the desktop file I meant to and didn't realize it before rebooting.

Modifying /usr/lib/systemd/user/gnome-session-manager@.service to pass --failsafe worked in the short term, and removing the symlink fixed the problem altogether.
