我有一个无头 ubuntu，我已尝试使用官方 Canonical Azure 映像以及官方 Canonical docker 映像。结果完全相同。
我已经安装了xfce和xrdp和xorgxrdp。我可以使用 MS 的两个 MobaXTerm 从我的 Windows 家用机成功创建远程 xrdp 会话mstsc。
我有 4K 显示器，所以我想设置比例 2。我无法在 GUI 中设置，因为虽然它允许从下拉列表中选择值 2，但按下“应用”按钮后，什么都没有发生，并立即设置回 1。
因此我尝试在配置文件中设置它：
sudo vim /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml
然后设置WindowScalingFactor为2
<property name="Gdk" type="empty">
<property name="WindowScalingFactor" type="int" value="2"/>
</property>
重新启动会话后，出现登录屏幕，输入我的凭据并按[确定]后，会话立即终止。
以下是 .xsession-errors 文件内容：

虽然分段错误的致命错误是软件本身的错误，修复超出了我们的范围，但我的用例非常常见，没有什么特别的额外内容，我可能错过了一些简单的配置和/或安装步骤。另请注意，我在我的 Azure 主机和 Docker 主机上都重现了完全相同的问题，因此那些图像细节和 infa 细节都不起作用……
我可能会错过什么呢？
