我正在使用 lightdm。我编译了lightdm-webkit-欢迎语从源头。
这是我的 /etc/lightdmlightdm.conf 设置：
[LightDM]
[SeatDefaults]
xserver-allow-tcp=false
greeter-session=lightdm-webkit-greeter
greeter-hide-users=true
user-session=i3
session-wrapper=/etc/X11/Xsession
[XDMCPServer]
[VNCServer]
（所有其他值都被注释掉，我在这里跳过了它们）
这是我的 /etc/lightdm/lightdm-webkit-greeter.conf：
[greeter]
background=/home/neo1691/Pictures/debian.jpg
theme-name=Elegant_revisited
font-name=Inconsolata bold 10
webkit-theme=Bevel
xft-antialias=true
xft-dpi=96
xft-hintstyle=slight
xft-rgba=rgb
当我启动笔记本电脑时，它只是进入黑屏，并且小光标闪烁，而不是启动 lightdm。
以下是日志文件：

这是 /var/log/lightdm/x-0-greeter.log 的输出

现在x-0.log的输出

如果我从 cli 运行 lightdm-webkit-greeter 命令，它会在 gtk 窗口中打开甜蜜的界面，并在终端上显示一些警告。
我还安装了 plymouth 软件包，只是为了让大家知道，在 lightdm.log 文件中发现与此相关的错误后。
如果您已经读到这里，我感谢您花费时间和精力阅读这么长的文章！任何帮助将非常感激。
干杯!
