I am able to login in through the terminal without any problem but when I enter my password in the login box(GUI) it doesn't show any error, just that is prompts me again to enter my credentials. I tried to enter other passwords but it gives me error.
This issue started after I created another user account on my system. Any ideas how cant I sort it out?
There can be many causes why that happened but here are a couple of things you can try.
sudo chmod -R ug+rwx /home/[username] and try logging in (return using Ctrl + Alt + F7)That should change .Xauthority permissions to yourself.
If that doesn't work try sudo chmod a+wt /tmp
If none of the above works you can try:
dpkg-reconfigure lightdm
