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?

  • Do you get any output when you log in through tty (a.k.a. 'terminal')? – Eduardo Cola Jan 10 '16 at 17:05
  • it works fine, the steps i follow now to login are: 1.login as guest, CTRL+ALT+F2 to switch to CLI, login with user and pass and it works – Raz Lets Jan 10 '16 at 17:22
  • Does any of the solutions to the question linked below solve your problem? I think you're experiencing a login loop which is a common problem caused by wrong usage, but which is usually easily fixable. – Byte Commander Jan 10 '16 at 17:32
  • You don't need to login as guest to use a tty. Just press Ctrl+Alt+F1...6 when you are in the login screen. – Eduardo Cola Jan 10 '16 at 17:33

There can be many causes why that happened but here are a couple of things you can try.

  1. Login into tty with your user (Ctrl + Alt + F1)
  2. Type 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
  • Reinstall Ubuntu

  • Hello guys, seems that i messed up something during my experimental exercise of creating/modifying usernames available for GUI login. After trying all the commands i found on forum i reinstalled Linux and everything works fine! good luck – Raz Lets Jan 11 '16 at 18:13
