Hi, I set up everything and wasn't able to start sessions via mstsc. Here is my log.

The connection log from mstsc window shows

connection problem, giving up
some problem

I hardly get any useful infromation from the log... Anyone can help? Thank you!

Same here... things i tried (without success - none of these solutions worked):

# install xrdp and related packages
sudo apt install -y xrdp gnome-tweak-tool

# replace allowed users in Xwraper.config
sudo sed -i 's/allowed_users=console/allowed_users=anybody/' /etc/X11/Xwrapper.config

# add policies

In my case it now works, after i installed xorgxrdp manually (there were problems with dependencies xorg-video-abi-23 and xserver-xorg-core).

After that, i used http://c-nergy.be/blog/?p=12043 to get rid of color profile warnings.

sudo apt install -y xrdp xorgxrdp xorg-video-abi-23 xserver-xorg-core
cat <<EOF > /tmp/45-allow-colord.pkla
[Allow Colord all Users]
Identity=unix-user:*
Action=org.freedesktop.color-manager.create-device;org.freedesktop.color-manager.create-profile;org.freedesktop.color-manager.delete-device;org.freedesktop.color-manager.delete-profile;org.freedesktop.color-manager.modify-device;org.freedesktop.color-manager.modify-profile
ResultAny=no
ResultInactive=no
ResultActive=yes
EOF
sudo mv /tmp/45-allow-colord.pkla /etc/polkit-1/localauthority/50-local.d/
sudo rm /var/crash/*
reboot

Now its working for me.

edit: Since the dependencies of xorgxrdp contain xserver-xorg-core, but in my case xserver-xorg-core-hwe is installed, that seems to be the problem with the dependencies. So to get the more recent release of xrdp and xorgxrdp you could also use the files from Ubuntu 19.04, which worked nicely in my case:

cd /tmp
wget http://archive.ubuntu.com/ubuntu/pool/universe/x/xrdp/xrdp_0.9.9-1_amd64.deb
sudo dpkg -i xrdp_0.9.9-1_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/x/xorgxrdp/xorgxrdp_0.2.9-1_amd64.deb
sudo dpkg -i --ignore-depends=xserver-xorg-core xorgxrdp_0.2.9-1_amd64.deb

# get rid of the color profile messages
cat <<EOF > /tmp/45-allow-colord.pkla

This solution fixed my problem too. Do you know the detailed meaning of the configuration file or where can I find such info. Thanks.
