I started up this morning, only to find my password is not working and I am locked out. When I enter the correct password, or when I try to login as a guest, the screen resets and goes back to the same login screen. In normal usage, I have disabled the lock screen, so I have no idea why it is occurring.
I can access my system via tty1. What can I do to remove the lock screen? I have tried several other threads, including changing the password via grub (no help). Thanks.
