X.org:1つの「デバイス」に2つの「画面」

X.org:1つの「デバイス」に2つの「画面」

Gentoo、Linux 3.7.10
X.Org X Server 1.13.4
GDM 2.20.11
GNOME 2.32.1
Radeon HD 6850カード、radeon xorgドライバ

2台のDVIモニターを備えたRadeon HD 6850カードがあります。このコマンドは、両方のモニターでミラー化されたデスクトップを表示できるファイルをX -configure生成しました。xorg.confもし私が行くならシステム->基本設定->モニターそしてリセットすべてのモニターに同じ画像を表示表示すると、デスクトップは両方のモニタに展開されます。

これは私が望むものとほぼ同じですが、1つの問題があります。ウィンドウを最大化すると拡張されます。両方モニターして醜いです。どのように変更できますか?

私の考えは、xorg設定を少し変更し、2つの「画面」セクション(モニターあたり)を持たせると、GDMは2つの異なる画面があると思い、2つの異なるデスクトップを作成することです。しかし、xorgは私の設定を無視しているようです(ログファイルにエラーが表示されず、私の設定が許可されているにもかかわらず)。 Xrandrはまた、画面が1つしかないと言います。

ところで、実際に私はグラフィックカード2枚とモニター3枚を持っています。ただし、問題はRadeonアダプタにのみ関連しています。
