How did I connect to Ubuntu 18.04 GNOME desktop from Windows 7 via xrdp?

Step 1

I installed GNOME:

apt install tasksel
tasksel install ubuntu-desktop
reboot

Step 2

I installed xrdp.
aptitude install xrdp did not work for me: the RDP session breaks after an authetication.
Only a compilation from sources works for me:

apt-get install git autoconf libtool pkg-config gcc g++ make  libssl-dev libpam0g-dev libjpeg-dev libx11-dev libxfixes-dev libxrandr-dev  flex bison libxml2-dev intltool xsltproc xutils-dev python-libxml2 g++ xutils libfuse-dev libmp3lame-dev nasm libpixman-1-dev xserver-xorg-dev
