Public bug reported:

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

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[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.
