If you upgrade from 16.04 LTS to 18 LTS, you might find your XRDP installation fails to start. My advice is to remove the XRDP package and purge the configuration files after backing them up.
I set up XRDP so infrequently, I’ve noted down some notes for reference below.
This uses XFCE4 to reduce overhead of the RDP connection. Remote desktop connections require a wired connection with low latency and little or no contention.
Update the system
Update the system using the following command:
# apt-get update
Install xfce4 using the following command:
# apt-get install xfce4
Install xrdp as follows:
# apt-get install xrdp
As the intended user, update xsession
$ echo "xfce4-session" > ~/.xsession
Edit the startwm.sh file
Edit the file as follows. Note I use a different technique here to most guides.
pico -$ /etc/xrdp/startwm.sh
Update the file at the end, as follows:
if test -r /etc/profile; then . /etc/profile fi # Uncommenting #test -x /etc/X11/Xsession && exec /etc/X11/Xsession #exec /bin/sh /etc/X11/Xsession # Addition below startxfce4
In the globals section add/update:
[Globals] crypt_level=none allow_multimon=false bulk_compression=true max_bpp=16 ls_title=Linux Server Login ls_bg_color=4f4f4f [Channels] rdpdr=false rdpsnd=false drdynvc=false cliprdr=false rail=false xrdpvr=true tcutils=true
Restart the service
# service xrdp restart
Now try a login using Remote Desktop Connection. Disable sound, clipboard and printer sharing to reduce requirements.
You should not use XRDP as a public-facing RDP service. The above configuration disables encryption so your traffic could be observed if intercepted.
