I have an error that seems to have been reported before but not solved by previous answers. When I try to log in as my primary account, I get a blackscreen and go back to the login menu. I am very confident this is due to me foolishly changing my password via terminal ("sudo passwd [user]") as I have been able to log in successfully, not to mention this started happening immediately after I restarted the computer from doing that. I would think I lost rights, or something like that.
What I have tried ("user" is symbolizing my actual account name, not the folder in root):
sudo chown -R user:user /home/user/ sudo chmod a+wt /tmp sudo chown user:user .Xauthority
Any help is greatly appreciated. Thank you.
P.S. Attempting to change my password via grub terminal gives something about a missing keyring...
