After updating my system using pacman, I can no longer login in from my display manager lightdm, nor from the TTY (using ctrl+ alt + f2 for example).
I tried to chroot from a live usb with an archiso, and the password works fine from it. I can change it using passwd, perform everything I need from there, but when I go back to logging in from lightdm or tty, password does not work.
I tried to create a new user with no password, but I cannot login with it either. I tried to change the password to something very simple, e.g., “test” or a single character, to check if it wasn’t a keyboard layout issue. Does not work either.
Even after chrooting again from a live usb, the password changes I made are still here so it is beiing applied.
Other stuff I tried that did not worked:
- Deleting the
.Xauthorityfile in my home directory
- Unlocking my user using
faillock --user myUsername --reset
Here are the logs from /etc/var/lightdm/lightdm.log :
It worked perfectly fine before this update and never had any issues.
Let me know if I can provide any other informations that could help.
