Ubuntu 11.04下Emerald不能用的問題解決

先吐槽下，這次更新時絕對是這麼多年來最差的一次，Ubuntu 11.04下N卡8400驅動居然用自帶的閉源受限驅動無效，還有各種不爽不說了。

相信用emerald的TX都會發現按F2後emerald --replace會導致標題欄消失。這次還是emerald不兼容compiz9.X造成的。下面說下解決方法：

第一步：准備一些編譯的基礎包，intltool貌似可以省略

sudo apt-get install git intltool libtool
sudo apt-get build-dep emerald
git clone git://anongit.compiz.org/fusion/decorators/emerald
cd emerald
git checkout -b compiz++ origin/compiz++

第二步：准備一個補丁文檔：vi emeraldfix.txt

其內容可以參看最下面論壇或者我搬來如下：

patch -p1 < emeraldfix.txt #打補丁，我的提示某些行出錯，不過也無影響

第三步：編譯階段，前面弄好的話就不會出錯了

./autogen.sh
./configure --prefix=/usr/local
make
sudo make install
sudo ldconfig

ok了，將compiz的窗口裝飾——命令裡改為emerald --replace，以後自動加載
