갑자기 올바른 비밀번호로 로그인이 안됩니다. (greeter,tty)

이것은 다른 비밀번호 관련 질문과 중복될 수 있지만 조금 이상합니다.

내 계정에 3개가 있어요우분투12.10시스템(표준 1개와 관리자 2명). 관리자 계정 중 하나가 내 기본 개발 계정인데 갑자기 어제 이상하게 동작하기 시작했습니다(최신 업데이트 이후 - 커널 및 기타:

• 존재하다웰컴 데스크, 비밀번호를 입력하면 즉시 "잘못된 비밀번호"가 반환됩니다. 확인도 하지 않습니다. (참고: 비밀번호는 절대적으로 정확합니다)
• 존재하다텔레타이프라이터, 로그인할 수 없습니다. 로그인 후 비밀번호를 입력하면 즉시 로그인하라는 메시지가 다시 표시됩니다... 계정을 인증하는 경로가 실수로 잠겼거나 액세스가 봉쇄된 것 같은 느낌이 듭니다.

두 번째 관리자 계정을 사용하여 로그인하고 문제가 있는 계정의 비밀번호를 운 좋게 변경하여 비밀번호를 원래 값으로 되돌리고 계정을 자동 로그인으로 설정했습니다. 다시 시작하고 계정이 로그인되었습니다. 그러나 예외 사항은 여전히 ​​​​존재합니다.

• 나루트 권한 작업을 수행할 수 없습니다(sudo 및 gksudo).. 비밀번호를 입력한 후에는 아무 일도 일어나지 않습니다. 비밀번호가 허용되는 유일한 시간은 화면이 잠겨 있고 화면 잠금을 해제하려면 비밀번호를 입력하라는 메시지가 표시될 때입니다.

내 홈 폴더의 소유권을 확인했는데 문제가 없습니다. 정말 도움을 주시면 감사하겠습니다.

요약하면: - lightdm을 통해 로그인할 수 없습니다. - sudo, gksudo 및 pkexec가 성공하지 못했습니다. - su 명령이 실패했습니다. - sudo 명령에 잘못된 비밀번호를 제공하면 확인하고 "비밀번호가 올바르지 않습니다."를 반환하지만 올바른 비밀번호를 제공하면 아무것도 반환하지 않습니다. - 자동으로 로그인하면 비밀번호 키링이 허용됩니다. - 화면 잠금을 해제하면 비밀번호가 승인됩니다.

• 비밀번호를 변경하고 내 사용자 이름이 그룹(sudo, admin, adm, ....) 등에 속하는지 확인했습니다.
