우분투 브리지 + ati9250 + dual 설치하기...

우분투 브리지 + ati9250 + dual 설치하고 있습니다만 잘 안되네요...
ati 홈페이지에서 ATI Driver Installer 8.21.7 을 다운받아 Installer instructions에
따라서 드라이버를 설치했고, /usr/X11R6/bin/aticonfig를 실행하여 xorg.conf를
구성하였습니다.
aticonfig 옵션은..

sudo ./aticonfig --initial=dual-head --dtop=horizontal --screen-layout=right --iagp=off -v

그리고 그래픽 카드는 다음과 같이 잡혀있습니다.

toma@toma:/etc/X11$ lspci | grep ATI
0000:01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01)
0000:01:00.1 Display controller: ATI Technologies Inc: Unknown device 5940 (rev 01)

흠... 드라이버가 잘 못 잡혀있는건가요???
위와같이 실행했을시에..
시스템/기본 설정/화면해상도에 2048x1024가 나오며. 선택시 이 해상도로 나오게 됩니다.
허나 모니터 한쪽만 나올뿐 right쪽은 나오지 않습니다... ㅡㅡ;; 절반이 안나오는...
정말 가슴이 아픕니다... 어찌해야 할까요???

아.. 그리고 DVI를 사용하는 모니터가 좀 흐릿한데... ati 그래픽카드 사용하시는 분들 원래 이런가요? 반품할까 생각중입니다... ㅡㅡ;

그럼 답변 부탁드리겠습니다..
