Ubunut 12.04下面安装了Teamviewer，刚安装完启动是没有问题的，每次重启打开就会提示：
"TeamViewer Daemon is not running
Please start teamviewerd and then restart TeamViewer."
命令行下，执行：sudo teamviewer --daemon start，又提示失败
后来发现teamviewer还有其他用法：
teamviewer --daemon status show current status of the TeamViewer daemon
teamviewer --daemon start start TeamViewer daemon
teamviewer --daemon stop stop TeamViewer daemon
teamviewer --daemon restart stop/start TeamViewer daemon
teamviewer --daemon disable disable TeamViewer daemon - don't start daemon on system startup
teamviewer --daemon enable enable TeamViewer daemon - start daemon on system startup (default)
执行红色enable命令，问题解决。
