Steps to reproduce

I am trying to get xrdp running on my ubuntu server. it was headless. I installed xcfe. I tried several fixes listed below to fix this issue. The problem seems to change a bit each time I apply a fix from the links below. Currently when I run: sudo systemctl status xrdp I get this:

[20230623-19:16:25] [INFO ] sesman connect ok
[20230623-19:16:25] [INFO ] sending login info to session manager, please wait...

@Wittytut - you haven't described what your issue is. What exactly is happening on your machine?

Can you fill in "Expected behaviour" and "Actual behaviour" above?

Thanks.

[Wittytut]

@matt335672 updated. :)

[matt335672]

Thanks.

There are a few possibilities here. Let's start with the basics

1. When you say "headless Ubuntu server", are you sure you aren't logged on to the machine console as the same user? This doesn't work on systemd-based systems. See this FAQ
2. How did you install XFCE?
3. What does the command update-alternatives --display x-session-manager tell you?
4. Have you added anything to ~/.xsession or ~/.Xsession?

@matt335672 Hi I am facing this similar issue while connecting to ubuntu 22 on azure from mac through microsoft remote desktop.

I do have XFCE4 installed

$ update-alternatives --display x-session-manager
x-session-manager - auto mode
  link best version is /usr/bin/startxfce4
  link currently points to /usr/bin/startxfce4
  link x-session-manager is /usr/bin/x-session-manager
  slave x-session-manager.1.gz is /usr/share/man/man1/x-session-manager.1.gz
/usr/bin/startxfce4 - priority 50
  slave x-session-manager.1.gz: /usr/share/man/man1/startxfce4.1.gz
/usr/bin/xfce4-session - priority 40
  slave x-session-manager.1.gz: /usr/share/man/man1/xfce4-session.1.gz

$ cat .xsession 
xfce4-session

@jp803333 - this may not be quite the same thing. Can you raise a separate issue please?

[jp803333]

Okay Creating one with the sesman logs

@matt335672 I have create the issue here.
