리눅스에서 듀얼 모니터를 사용할
 수 있다구 해서 kldp에서 xinerama문서를 보구 따라 해봤습니다
XF86config는 건드려본적두 없구 워낙 초짜라서 무슨말인지 모르구
헤메던 중에 xf86cfg라는 프로그램을 발견(?)하구 이걸루 설정 했습니다
 우선.. 제가 설정해 노은 XF86config-4입니다

 전 레드햇 71을 쓰구
노트북을 사용 하기때문에 비디오 카드 한개구
디바이스 세션에  버스아이디는 PCI:1:0:0이걸루똑같이 했구요
문서랑 비교해보면 별루 틀릴게 없는데 왜 안되는 지 모르겠네영
 실행 할때두 startx -- +xinarama 이렇게 하구,그넘을 쓰는데....
 혹시...xinarama이넘이 프로그램인가여?????-_-;
 듀얼 모니터에 관한 내용은 어디 가두 찾을 수가 없던데...오직 문서만 딸랑 -_-;
듀얼 모니터 설정에 성공 하신 분은 꼭 답변좀 부탁드립니다
제 모니터가 썩구 있어여 (비싼곤데..ㅡ.ㅜ)-- 요즘은 초보라는 핑계를 대는것보단 머리가 
나빠서 그런가 보다 하구 생각이 드네요... ㅡ.ㅜ
oh~~~~jesy~~~~~
