I've installed mate and xrdp on Ubuntu 18.04. Now I try to connect to this PC from another Ubuntu with Remmina:

enter image description here

I press OK, login window disappears background is same,nothing happens. My ~/.xsession contains mate-session.

xrdp.log contains stuff like this:

How do I fix or diagnose this brilliant piece of software?

You do not specify exactly which version of Ubuntu 18.04 you are running. If you have doe all the updates, you should be running Ubuntu 18.04.3.... You can check this by running the following command:

lsb_release -sd

If you are running Ubuntu 18.04.3, there is a known issue with xrdp package provided by Canonical. The xrdp package cannot install the xorgxrdp package because of failed dependencies. This is why you cannot connect remotely to your Ubuntu.

Best option - Install the new xorgxrdp-hwe-18.04 package

Install the new xorgxrdp package by issuing the following command:

sudo apt-get install xorgxrdp-hwe-18.04

This should fix your issue .

Dirty Quick Fix - Downgrade the xorgxserver package

We assume that you have already installed xRDP package and you want to fix it

sudo apt-get install xserver-xorg-core
sudo apt-get -y install xserver-xorg-input-all

More info on http://c-nergy.be/blog/?p=13390.

Better fix - use unofficial xrdp packages working with Ubuntu 18.04.3

Note: To use this option, please remove the xrdp package you have installed

sudo add-apt-repository ppa:martinx/xrdp-hwe-18.04
sudo apt-get update
sudo apt-get install xrdp xorgxrdp

More info at http://c-nergy.be/blog/?p=13455.

Other option - use a script to perform the installation for you

Note: To use this option, please remove the xrdp package you have installed.

To use Ubuntu repository xrdp packages, read instructions and download the script at http://c-nergy.be/blog/?p=13933.

To compile from source (easy way), read instructions and download the script at http://c-nergy.be/blog/?p=13663.

I have found an alternative solution:

apt-get install x2goserver

This will install x2go, which is opensource remote desktop server for Linux with x2goclient available both for Linux and Windows.

    The xrdp status is so poor, that this answer should be advertised everywhere. I've lost a lot of hair chasing xrdp issues, when x2go just worked. It doesn't even show up on Google when searching related terms, what a shame. – Marcus Jan 3 at 22:11

The following worked for me on 20.04 (I think it applies to 18.04 too):

In /etc/xrdp/startwm.sh change #!/bin/sh to #!/bin/bash

I found this fix in this comment. A few more details from that comment:

My issue was caused by custom scripts in /etc/profile.d with syntax that /bin/sh doesn't like (e.g. function function_name { some; commands; }).

This comment was from a known issue on the bug.

There was another comment there mentioning another fix that did not apply to my situation:

This post seemed to fix it for me: http://catch22cats.blogspot.com/2018/05/xrdp-blank-screen-with-ubuntu-1804.html

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.
