最近，不小心将自己的Ubuntu-12.04桌面系统搞坏了，主要是由于改变了/var目录下文件的属主，结果桌面系统崩溃了，启动都成问题了。不过还算幸运，可以通过其他的机器登录到我的系统上。根据别人的系统/var目录下的文件属主信息，一点点还原回去了，但是没有彻底解决问题：每次启动电脑时，都提示错误“The system is running in low-graphics mode”，如图所示：

然后，你点击“OK”按钮，只能通过一个单一的会话选项进入到桌面系统，很是不方便。

在网上查了一下，解决的方法很多，终于找到了一个适合我这里问题的方案，引用如下：

*I have recently received a similar issue with myPangolin Performance laptop. The folks at System 76 told me to do the following:*

*Click Okay and then select the option to get a terminal. (alternatively you can press ctr+alt+f1 to bring up another tty)*

sudo chown lightdm:lightdm -R /var/lib/lightdm sudo chown avahi-autoipd:avahi-autoipd -R /var/lib/avahi-autoipd sudo chown colord:colord -R /var/lib/colord

*reboot*

*These commands did the trick for me.*
