ubuntu 18.04 / 20.04 xrdp

download 18.04 server ISO
use unetbootin 661 write USB
Install w/o any server package (minimal)

$sudo apt update
$lsb_release -a
$hostname -I
$hostname
$getconf LONG_BIT
$sudo apt-get install xrdp
$sudo apt update
$sudo apt-get install mate-core
$sudo apt-get install mate-desktop-environment
$sudo su
#sed -i.bak '/fi/a #xrdp multiple users configuration \n mate-session \n' /etc/xrdp/startwm.sh
#exit
$diff xrdp/startwm.sh /etc/xrdp/startwm.sh
$sudo ufw allow 3389/tcp
$sudo /etc/init.d/xrdp restart


From Windows 10, mstsc (remote desktop) can connect to the server

Ubuntu 20.04
https://github.com/neutrinolabs/xrdp/issues/1358
$sudo apt-get install xrdp
$sudo systemctl enable --now xrdp
$sudo ufw allow from any to any port 3389 proto tcp

unset DBUS_SESSION_BUS_ADDRESS
unset XDG_RUNTIME_DIR
. $HOME/.profile

By adding the above lines just before the test and exec in /etc/xrdp/startwm.sh, I also added the #!/bin/bash to the top of the file - also doing a chmod after you've changed the file is what some users might be forgetting.



Basically adding the line:
X-GNOME-Autostart-enabled=false

To the files:
/etc/xdg/autostart/spice-vdagent.desktop
/usr/share/gdm/autostart/LoginWindow/spice-vdagent.desktop

Then stop and disable the service:

$ sudo systemctl stop spice-vdagentd

$ sudo systemctl disable spice-vdagentd

$ systemctl status colord
