Contents

• 1 Step1: Install XRDP remote desktop
• 2 Step2: Edit /etc/xrdp/startwm.sh
• 3 Step3: Edit /etc/xrdp/xrdp.ini
• 4 Step4: Disable light-locker
• 5 Step5: Start xrdp service
• 6 Step6: Test the remote desktop connection

1 Step1: Install XRDP remote desktop

Enter the following command to install:

sudo apt install  -y tigervnc-standalone-server xrdp
 sudo  sed  -e  's/^new_cursors=true/new_cursors=false/g'  -i  / etc / xrdp / xrdp.ini

2 Step2: Edit /etc/xrdp/startwm.sh

Edit /etc/xrdp/startwm.sh:

sudo  vim  / etc / xrdp / startwm.sh

Comment out the last two lines in the file (comment method: add # sign at the beginning of the line), as shown below:

# test -x /etc/X11/Xsession && exec /etc/X11/Xsession 
# exec /bin/sh /etc/X11/Xsession

Then add the following at the end of the file:

lxsession -s LXDE -e LXDE

3 Step3: Edit /etc/xrdp/xrdp.ini

Edit /etc/xrdp/xrdp.ini

sudo  vim  / etc / xrdp / xrdp.ini

Scroll to the address of "; Session types", delete all other session types, only [Xvnc] is left:

;
; Session types
;
; Some session types such as Xorg, X11rdp and Xvnc start a display server.
; Startup command-line parameters for the display server are configured
; in sesman.ini. See and configure also sesman.ini.
 [ Xvnc ] 
name =Xvnc
 lib =libvnc.so
 username =ask
 password =ask
 ip =127.0.0.1
 port =- 1 
#xserverbpp=24 
#delay_ms=2000

4 Step4: Disable light-locker

Since light-locker will not work properly in the XRDP environment, we need to disable it in the XRDP environment. In order not to affect the real environment, here we use a packaging script to solve the problem. First, rename the original file:

the sudo  CP  / usr / bin / Light-Locker / usr / bin / Light-locker.orig
 the sudo  RM  / usr / bin / Light-Locker

Create another script to call it, and use the editor to create a file /usr/bin/light-locker with the following content:

#!/bin/sh
 
# The light-locker uses XDG_SESSION_PATH provided by lightdm. 
if  [  !  -Z  " \$ {XDG_SESSION_PATH}"  ] ; then 
  / usr / bin / light-locker.orig
 else 
  # Disable light-locker in XRDP. 
  true 
fi 
EOF

Give the script executable permissions:

sudo  chmod  755  / usr / bin / light-locker

5 Step5: Start xrdp service

sudo systemctl enable xrdp
 sudo systemctl restart xrdp

6 Step6: Test the remote desktop connection

Use the Microsoft Remote Desktop client to create a new connection, the address is the IP address of the development board, and the user name and password are pi. In order to get a better experience, the resolution is recommended to be set to 1280x800, and the color depth is 24 bits. The settings are as shown in the figure below. Shown:

After the connection is successful, as shown in the figure below:
