우분투7.04 에서 듀얼 모니터 사용 문제

아무리 찾아봐도 알수가 없네요 ㅠ,.ㅠ;

조언좀 부탁 드립니다.

우분투 7.04에서 듀얼 모니터를 사용하고자 합니다.

ATI x300 모델 사용중이고 19인치랑 17인치 모니터 이렇게 사용하고 있습니다.

Ati에서 드라이버 다운 받아서 실행 하니 아래와 같이 에러 메시지 뜨면서 되질 않네요.

xf86cfg라는 프로그램으로 xorg.conf 파일 설정을 만들라는데, xf86cfg라는 프로그램은 찾을 수가 없네요.... 우분투에만 없는 건지.. ㅡ,.ㅠ

제. xorg.conf 파일도 첨부 합니다.
