radeon 2100(740g integrated) *ERROR* Raw EDID

예전에 ATI로는 해본적이 없던가..?
아무튼 처음에 부팅할때 이상하게 화면이 자주 깜빡이고 모니터도 색상이 이상하게 나오다가
겨우잡는 현상이 발생되서 자세히 보고 있으니, 부팅메시지 중에도 EDID Error가 나오길래
dmesg로 보니 아래와 같이 촤르르르륵

그래서 찾아보니 머.. 결론은 i2c를 통해서 EDID정보를 받는데 그 부분의 드라이버 설정이 오류가 있는지
다시 컴파일을 해주어야 한다~ 머 이런거.. 지금와서 ATI에서 다시 드라이버 리눅스용으로 받으면 해결이 되려나?

혹시나 해서 찾아봤지만.. 리눅스 내장 드라이버 아닌, ATI 공식 드라이버는 XP/VISTA용 밖에 없는듯 하다.
