One day, suddenly it turned that I couldn’t login desktop even if I enter correct password. Stackoverflow said that the reason is ~/.Xauthority permisson.
$ ls -lA ~/.Xauthority
-rw------- 1 aminami aminami 51 4月 26 21:11 .Xauthority
$ chown {user_name}:{user_name} ~/.Xauthority
It solved the problem.
