# Ubuntu桌面循环登陆问题

|
||||
|
||||
描述:在安装了x11-apps和vnc后,发现vnc不好用所以删除了vnc。结果就导致了Ubuntu登陆界面循环登陆,在密码输入正确后闪烁一下然后接着又要输入密码。
|
||||
|
||||
方案1:网络上好多提到这个方案,但是似乎没有太大作用。
|
||||
|
||||
```shell
|
||||
# ctrl + alt + f1 \ f2 根据实际情况看看f1和f2哪个能进入tty命令行
|
||||
ctrl + alt + f2
|
||||
# 进入主界面
|
||||
cd ~
|
||||
ls -lA
|
||||
# 如果看到 -rw----------------------- 1 root root 53 Nov 29:10:19 .Xauthority
|
||||
# 整理的username是用于登陆的用户名
|
||||
chown username:username .Xauthority
|
||||
```
|
||||
|
||||
方案2:罗瑞迪亲测解决
|
||||
|
||||
```shell
|
||||
sudo apt-get install lightdm
|
||||
# 然后在弹出的Configuring lightdm界面中选择lightdm
|
||||
```
