Glad it's solved! Thanks for letting us know and for telling us what caused it: it may help other users who run into the same login loop.

If anything else comes up, we're here.

Thanks for letting us know. That loop back to GDM usually has a specific cause, and we can narrow it down from a TTY. Press Ctrl + Alt + F3 at the login screen, log in with your user and try this:

1. Check that the disk hasn't filled up, neither space nor inodes:

df -h
df -i

2. Look at the errors from the current boot:

journalctl -b -p err --no-pager | tail -n 60

3. Check that your home folder and its files belong to your user and not to root:

ls -ld ~ ~/.profile ~/.cache ~/.local

4. See which snaps you have installed. If you suspect one of them, you can remove it from the TTY:

snap list
sudo snap remove NAME

5. To rule out a damaged profile, create a test user, log out and try to log in with it:

sudo adduser test

If it works with the new user, the problem is in your profile. Please paste the output of steps 1 to 4 here and we'll take a look.

Thanks and best regards,
