Debian Wheezy 설치 문제

나는 최근에 4GB nVidia 그래픽 카드가 장착된 노트북에 Debian Wheezy 7.6을 설치했습니다. 기본적으로 로그인하면 그놈 클래식 모드로 부팅되어 보고됩니다."Gnome 3를 로드하지 못했습니다.". 또한 마우스 포인터가 일관성이 없는 경우도 있습니다(스크롤 및 클릭 시 표시되지 않음).

이것은 다음의 출력입니다 .xsession-errors.

나는 이것이 무엇인지 모른다. 구글링을 했는데 해결책을 찾을 수 없었습니다. 내 그래픽 카드 때문인가요? 그렇다면 어떻게 해결할 수 있습니까?

업데이트: 저는 정말 gnome-3을 원하지 않지만 클래식 모드는 원하지 않습니다. 따라서 클래식 모드가 충분히 완벽하면 충분합니다.
