Linux Mint에서 화면 해상도 변경

방금 Linux Mint 14를 설치했는데 화면 해상도를 변경할 수 없습니다. 1920 x 1200의 적절한 해상도는 옵션이 아닙니다.

나는 열심히 노력했다이것솔루션이지만 다음과 같이 보고합니다.

xrandr: cannot find output "VGA1"

나도 시도했다이것, 하지만 다음과 같이 보고됩니다.

Fatal server error:

    If this server is no longer running, remove /tmp/.X0-lock
    and start again.
