[해상도문제]KUBUNTU 설치하신 분 중에 Geforce6600쓰시는 분요..도와주세요..

최후에 수단을 사용합니다.. 도저히 안되겠어서..-_-;; 이렇게 글을 올립니다.
요근래 우분투에 미쳐서 살고 있습니다만.. 데스크탑에만..
nVidia 드라이버를 설치한 뒤에 컴이 느려지거나 (Gnome에서)
해상도 고정 640*480으로 고정이 되는 그런 문제가 발생합니다.(KDE에서)

제 파일입니다.

이렇게 했는데도 불구하고..-_-;; 컴퓨터를 부셔버리고 싶을 정도로..-_-;;
베릴설치는 고사하고 해상도 맞추는것만 벌써 일주일째입니다.ㅜㅜ
고수분들의 의견을 듣고 싶습니다.. 부탁드립니다.
