sudo apt-get install ubuntu-desktop unity compizconfig-settings-manager

sudo apt-get install ubuntu-desktop unity compizconfig-settings-manager

compiz出現錯誤：

cd ~

切換到自己的home目錄之後，

rm -rf .cache/compiz
rm -rf .cache/compiz-1
rm -rf .cache/compizconfig-1
rm -rf .config/compiz
rm -rf .config/compiz-1
rm -rf .config/compizconfig-1
rm -rf .gconf/apps/compiz
rm -rf .gconf/apps/compiz-1
rm -rf .gconf/apps/compizconfig-1

好像刪完這個.config/compiz-1 好像就自動恢復了。

export DISPLAY=localhost:0
ccsm
compiz

安裝了mysql 後，啟動時，程式提示 “No directory, logging in with HOME=/”
sudo service mysql stop

sudo usermod -d /var/lib/mysql/ mysql //使用usermod命令來重新定位mysql所在的目錄

sudo service mysql start
