Create service configuration file:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
−
xrandr --output HDMI-1 --transform 0.80,0,-35,0,1.04,-19,0,0,1
+
sudo vi /lib/systemd/system/x11vnc.service

===eDP LCD Display Rotation===
+
[Service]
−
If you want to rotate an eDP LCD's display you can do it by commanding "xrotate.sh" to rotate its display to 90/180/270 degrees.
+
Type=simple
−
You can rotate display clockwise by 90 degrees by running the following command as root. This command calls lightdm to make your change effective immediately:
+
ExecStart=/usr/bin/x11vnc -display :0 -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pwd -rfbport 5900 -shared -capslock -nomodtweak
−
<syntaxhighlight lang="bash">
+
ExecStop=/usr/bin/x11vnc -R stop
−
sudo xrotate.sh -m CW -r
+
Restart=on-failure
−
</syntaxhighlight>
+
−
For more details about its options you can run "xrotate -h".<br/>
+
−
Note: this command doesn't support HDMI display's rotation. If you want to rorate an HDMI's display you need to refer to X11's tech documents and make changes in "/etc/X11/xorg.conf".

1 Account & Password

Regular Account:
    User Name: pi
    Password: pi

Root:
    the root user account is disabled by default, you may configure the root password through the 'sudo passwd root' command.

2 View IP address

Since the Debian Buster hostname is the hardware model by default, you can use the ping command to get the IP address:ping {{{1}}}

3 Connect to Debian via SSH

Run the following commandssh pi@{{{1}}}
The default password is: pi

4 Update Software Packages

$ sudo apt-get update

5 Install x11vnc Server on Debian for Remote Access

5.1 Install x11vnc server

The following command to install x11vnc server: 

sudo apt-get install x11vnc

5.2 Set your password

sudo x11vnc -storepasswd /etc/x11vnc.pwd

5.3 Setup x11vnc server with systemd auto start up

Create service configuration file: 

sudo vi /lib/systemd/system/x11vnc.service

Let’s copy and paste the following configuration into our newly create service file:

ExecStop=/usr/bin/x11vnc -R stop
Restart=on-failure
 
[Install]
WantedBy=multi-user.target

The following commands to reload the systmd system and to enable and start the x11vnc service: 

sudo systemctl daemon-reload
sudo systemctl enable x11vnc.service
sudo systemctl start x11vnc

5.4 Testing remote access

Start the VNC client software, input IP:5900 to connect:
Debian10-x11vnc.png

6 Install the kernel-header package

sudo dpkg -i /opt/linux-headers-*.deb

try to compile a kernel module: 

sudo apt update
