我希望有人能帮助我解决这个问题。我遵循以下教程：https://linuxize.com/post/how-to-install-xrdp-on-ubuntu-18-04/
安装 VirtualBox 后重新启动时，我再也无法登录 xfce。一旦我填写了我的用户，并通过，它就会进入黑屏，然后踢出会话。
我有一个 .xorgxrdp 日志，如下所示：

答案1
我无法确定最初的确切原因，但我认为正如 guiverc 提到的那样，我可能对 root 帐户做了一些事情，并更改了我的 xsession 文件的所有权。也就是说，我删除了 ~/.xsessions-errors 文件，并在正确的用户下创建了一个新文件，这似乎已经为我解决了问题，但为了确保万无一失，我在进入桌面后获得了所有 xsession 文件的所有权。
