HDMI port

Disclaimer

Keonn Technologies S.L. does not officially support the use of the mini-HDMI port.

Keonn does not guarantee the mini-HDMI port will work in any combinations of: monitor, HDMI cable, monitor configuration and reader configuration.

Keonn can only confirm certain combinations have proved to work.

HDMI port activation requires the use of root access to the reader device. Root access is also subject to the embedded development warranty implications

Additionally, please note that:

All Keonn readers are class B under EN 55022. When the HDMI port is used, the device may cause radio interference in which case the final user is the sole responsible for taking adequate measures.

6. Remember to check the ownership and permissions, if they are different, the system will not boot. To make sure the properties of the file are correct, run the following commands:

sudo chown root:root /boot/uEnv.txt

sudo chmod 644 /boot/uEnv.txt

Graphical desktop

By default, the screen that will show is a terminal, but a graphical desktop can be installed. To do so, run the following commands:

sudo apt-get update

sudo apt-get install -y xfce4 (it may take several minutes to complete)

sudo echo "exec ck-launch-session startxfce4" > /home/keonn/.bash_login

sudo chown keonn:keonn /home/keonn/.bash_login

sudo chmod 644 /home/keonn/.bash_login

sudo reboot
