RK3399 UBUNTU 重启后无法进入lightdm GUI

lanyaye

你好，
我安装官方镜像：Firefly-rk3399_xubuntu1604_201705111112.7z
第一次能够进入lightdm, GUI很棒


但是在我运行
sudo apt update
sudo apt upgrade
以及安装ROS及一些软件后，重新启动后，再也无法进入lightdm


lightdm log显示
sudo cat /var/log/lightdm/x-0.log

我尝试了删除lightdm及重新安装
sudo apt purge lightdm
sudo apt install lightdm
还是不行。


请问有什么办法在不重新刷机得情况下能进入lightdm
多谢！

我重新刷官方的Firefly-rk3399_xubuntu1604_201705111112.7z
我尝试了刷最新的Firefly-rk3399_xubuntu1604_201707041527但是我的板子好像起不来，HDMI没有任何输出

我重启后不能进入GUI lightdm的原因是我可能运行了
sudo apt autoremove
这个会删除下面得包
The following packages were automatically installed and are no longer required:
  libllvm3.8 libmircommon5 libxfont1 x11-apps x11-session-utils xfonts-base xfonts-encodings xfonts-scalable xfonts-utils
  xinit xinput xserver-common xserver-xorg-core xserver-xorg-input-all xserver-xorg-input-evdev
  xserver-xorg-input-synaptics xserver-xorg-input-wacom
Use 'sudo apt autoremove' to remove them.
可能导致xorg无法启动
无法进入gui原因可能不是这个，但是还是在这里提醒大家不要运行这个命令

也希望官方的镜像能提供更加稳定得镜像，就像树莓派一样，毕竟还是很多人不是发烧友定制自己得镜像。
谢谢！

没错，就是不能 autoremove， firefly 的版本应该是精简了桌面包里面带的一些软件，导致系统依赖关系把xorg的一些库识别为不再需要。清掉之后再安装也恢复不了。
