I have a headless ubuntu, I've tried this with official Canonical Azure image and also with official Canonical docker image. The result exactly the same.
I've installed xfce and xrdp and xorgxrdp. I can successfully create a remoted xrdp session from my Windows home machine both using MS's mstsc both MobaXTerm.
I have 4K display, so I want to set scale 2. I can not set in the GUI, because althoug it allows to pick the value 2 to pick from the dropdown list, after pressing Apply button, nothing happens, and instantly set back to 1.
So I've tried to set it in the configuration file:
sudo vim /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml
then set WindowScalingFactor to 2
<property name="Gdk" type="empty">
<property name="WindowScalingFactor" type="int" value="2"/>
</property>
After restarting the session, the logon screen appears, and after giving my credentials and pressing [OK], the session instantly terminates.
Here is the .xsession-errors file content:

Although a fatal error of segmentation fault is an error in the software itself which's fixing is beyond our scope, still my use case is so usual and nothing special extra it is possible I am missing some trivial configuration and/or installation step. Also note, I've reproduced the excactly the very same issue both on my Azure host, and my Docker host, so no those image specifics, neither infa specifics do not play a role...
What possible thing could I miss here?
