[3D Desktop 2]

問題が発生していたものですがTWINVIEWの機能を使えば問題なく動きました
以前はスクリーン間にウィンドウを通すとカクカクしていたのもなくなったし

３Dデスクトップ環境を使用するために。

・xorg.confの設定追加
# nvidia-xconfig --composite
# nvidia-xconfig --render-accel
# nvidia-xconfig --add-argb-glx-visuals -d 24

・Conpizインストール
# yum install gconf-editor
# yum install compiz
compiz.i386 0:0.0.13-0.37.20060817git.el5.centos.1
[システム]-->[設定]-->[デスクトップ効果]で有効

・Beyrlインストール

-->Repository

# yum --enablerepo=kbs-CentOS-Testing install beryl* emerald*

システムツールに宝石のアイコンのbeyrlがあるのでそこから起動できる。
ただ、いまの環境だとデュアルモニタでウィンドウ移動できるように
xorg.confで設定してある
Option "Xinerama" "on" が無理っぽい、やむえずoffにしてX立ち上げて
beyrlを起動すると片方のモニタが無反応になってしまう
