** Description changed:

  I am trying running unity under a multipass vm running on remote
  dedicated root server (24 core/64GB) on linode running 22.04
  
  According to this guide a full dektop can be used:
  https://multipass.run/docs/set-up-a-graphical-interface which runs a
  full ubuntu-desktop.
  
  Multipass vm also initiated with 22.04. Nginx forwarding *:3389 to
  <multipass-vm-ip>:3389
  
  Then from inside vm,
  
  1. sudo adduser xrdpuser (#default ubuntu doesn't have passwd )
  2. sudo usermod -aG sudo xrdpuser && sudo usermod -aG tty xrdpuser && sudo usermod -aG video xrdpuser
  3. sudo apt install ubuntu-unity-desktop (Or minimal installation from )
- 4. Sudo apt install xrdp; sudo usermod -aG ssl-certs xrdp
+ 4. sudo apt install xrdp; sudo usermod -aG ssl-certs xrdp
  
  Unity install unity binary under /usr/share/xsessions which basically
  runs /usr/libexec/run-systemd-session unity-session.target
  
  5. Edit /etc/xrdp/startwm.sh and comment out xsesion binary and put the
  above line
  
  #test -x /etc/X11/Xsession && exec /etc/X11/Xsession
  #exec /bin/sh /etc/X11/Xsession
  #xfce4-session
  /usr/libexec/run-systemd-session unity-session.target
  
  6. sudo systemctl restart xrdp && sudo systemctl restart xrdp-
  sesman.service
  
  7. Now when connecting from remmina I get following errors:
  
  Full Log: https://pastebin.ubuntu.com/p/R2fyGq4VRv/
  
  Interesting parts
  
  /bin/sh: 1: initctl: not found which I think is this bug:
  https://bugs.launchpad.net/ubuntu/+source/gnome-keyring/+bug/2002978
  
  Then We get errors like
  
  unity-settings-daemon[4467]: Unable to initialize GTK+
  
  compiz-profile-selector[4516]: Error: unable to open display.
  
  (Compix uses unity-lowgfx and tries to start but still fails due missing
  display.)
  
  Xrdp however succesfully connecting display 10 as per above log.

  Jun 22 14:52:15 jammy-vm xrdp-sesman[4326]: [INFO ] Starting the default window manager on display 10: /etc/xrdp/startwm.sh
  Jun 22 14:52:15 jammy-vm xrdp-sesman[4316]: [INFO ] Session in progress on display 10, waiting until the window manager (pid 4326) exits to end the session
  
  What could be issue here ? xfce4 session works perfectly fine with same
  configuration.
