烧完镜像，没有进行任何操作，只是改了个国内的源，apt-get update ， apt-get upgrade 就启动不了桌面。
串口调试输入正常，但是有登录请求，原来开机自动登录到root用户，现在需要手动登录，且root用户没有开启了。如下：
[ OK ] Reached target Network is Online.
Starting /etc/rc.local Compatibility...

[ OK ] Started crash report submission daemon.

Ubuntu 18.04.1 LTS firefly ttyFIQ0
firefly login:
桌面进入不了，左上角一直有个光标闪动就没有其他现象了。关掉桌面服务后，开机可以用字符界面登录，但sudo lightdm后又出现相同现象。
进一步排查发现，X server启动失败，发现X Server的日志报错：
