Radeon5450を導入。しかし...

今まで使っていたグラボがNvidia7300LEに見切りをつけ、玄人志向のRadeon5450 GDDR3 512Mを導入。
Windows側では簡単に認識し、動画再生支援も効く。

しかし問題がUbuntu側
Ubuntuに用意されているプロプラエタリなドライバを導入しても、ATIからドライバをダウンロードして入れても

$ fglrxinfo
zsh: segmentation fault  fglrxinfo

aticonfigでxorgの設定を作って再起動すればGrubを抜けてUbuntuのロゴが出る所で5個の点が全部付いたまま動かなくなるし。
UbuntuForumに聞くべきだろうか。
