Ubuntu遇到的问题

1）Ubuntu将应用添加到收藏夹

将*.decktop文件在/usr/share/applications/

decktop示例：

[Desktop Entry]
Name=IntelliJ IDEA
Comment=IntelliJ IDEA IDE
Exec=/home/nufail/apps/idea-IC-107.587/bin/idea.sh
Icon=/home/nufail/apps/idea-IC-107.587/bin/idea_CE128.png
Terminal=false
StartupNotify=true
Type=Application
Categories=Development;IDE;

 2）Ubuntu无法打开系统设置

sudo apt-get install gnome-control-center
