连接到 WSL/Ubuntu 20.04 LTS 时远程桌面连接崩溃

Question

我正在尝试在 WSL 中运行适用于 Ubuntu 20.04 的 XFCE 桌面环境（不是 WSL2，仅供参考。我的笔记本电脑不支持虚拟化）。

我已经安装xrdp，xfce4并且xubuntu-desktop正在使用sudo apt install <package-name>。

我还重新检查了，甚至使用sudo service xrdp status和重新启动了 xrdp 服务sudo service xrdp restart。该服务似乎正在运行。

但是，在尝试使用Remote Desktop Connection（mstsc）连接到远程桌面时，它会建立连接，似乎确认身份验证正确并简单地关闭（不显示桌面）。

这是来自的日志xrdp.log

我尝试使用127.0.0.1和进行连接172.20.10.2，两者都产生相同的结果。

我也尝试过/etc/xrdp/startwm.sh像在互联网上看到的那样进行编辑（注释掉最后两行并添加startxfce4）。这似乎没有什么区别。

PS 请不要推荐使用 或类似的本地 Xserver 应用程序的解决XLaunch方案XMing。这些确实有效，但我出于特定原因选择使用 RDP。

提前致谢。

Answer 1

添加到接受的答案中，如果该行test -x /etc/X11/Xsession && exec /etc/X11/Xsession已取消注释但您的 RDP 连接崩溃，则注释现有行并添加新行startxfce4。所以文件的最后几行/etc/xrdp/startwm.sh应该是：

# test -x /etc/X11/Xsession && exec /etc/X11/Xsession
# exec /bin/sh /etc/X11/Xsession

startxfce4

Answer 2

#exec /bin/sh /etc/X11/Xsession我通过打开文件取消注释命令解决了这个问题 sudo nano /etc/xrdp/startwm.sh
