@yangtukun1412 一语惊醒不懂人啊，我基本没正儿八经看过日志，果然有问题：

最多二千字，上图片 
 | 1 dltsgl Jun 29, 2016 试试其他的启动器呢 |
 | 2 yangtukun1412 Jun 29, 2016 这种问题不看日志怎么查... |
 | 3 bdbai Jun 29, 2016 via Android startx 本来就是一个用来启动桌面的脚本。如果要开机进入桌面可以试试 systemctl enable gdm |
 | 4 delavior OP @bdbai enable 只是设置开机启动， systemctl start 就是启动， start 都启动不了， enable 不是一样吗 |
| 5 delavior OP @yangtukun1412 还要看日志啊，我基本都是用爱发电，没看过日志，我找找看 |
