I have installed Ubuntu 18.04.2 (LTS). It was working smoothly for some days. But now I can't login. When I try to get into the desktop by entering the valid password and hit enter button, after 5-6 seconds the screen splashes and the login screen appears again. I can login into my account with the shell by pressing `Ctrl`+`Alt`+`F2` and get back into the GUI login screen by holding `Alt`+`Left` until that appears. I have tried all solutions in the question [Ubuntu gets stuck in a login loop](https://askubuntu.com/questions/223501/ubuntu-gets-stuck-in-a-login-loop). But all failed to login into my account. One answer suggested me to create new user with permission to use the sudo command. With that new account I can login. But when I try to login with the previous account the login loop continues. I need to access that account. An answer suggested me to check the permission of .Xauthority, but it doesn't exists. I have also tried to get into the GUI by executing `startx` command in the shell. This works and appears a GUI on the new account but not on the previous account. Unfortunately I don't get an have an internet connection on Ubuntu. So I can't use apt or apt-get command. But I have a Windows PC with administration rights and internet connection. May something occurred in my home directory.
