我按照https://support.google.com/chrome/answer/1649523上的说明尝试设置chrome远程桌面，但
/usr/sbin/lightdm-session（仅限lightdm和lightdm-gtk-greeter）对于上下文，我正在运行Debian 9 stretch（amd64），xfce4 4.12.3和lightdm 1.18.3-1。
我尝试了几种不同的方法：
1。尝试＃1

4。尝试＃4
这一次，我刚刚删除了~/.chrome-remote-desktop-session。它似乎成功了！远程连接已成功启用，我可以通过手机连接到它。但是，重新启动计算机后，我发现我无法再通过lightdm登录，但仍然可以通过手机连接。 Lightdm让我输入我的凭据，但只是在打印了一些X服务器启动后返回到登录屏幕。当我尝试通过lightdm登录时，打印了以下日志消息：
