Starting from this image i’m creating an image for a BBB running a “kiosk” application.
This is a second try, as i had some strange xserver errors in my first attempt.
This is what i’ve done from the first boot (history):
1 wpa_cli
2 ifconfig wlan0
3 hostnamectl
4 sudo reboot
5 sudo nano /etc/ssh/sshd_config.d/sshd_as_root.conf
6 sudo service sshd restart
7 timedatectl
8 sudo apt update && sudo apt upgrade -y
Here, by using winSCP on a Win10 PC, i’ve changed some /boot/uEnv.txt lines, commenting out enable_uboot_cape_universal=1 and adding 3 custom dtbo.
Also edited /etc/systemd/network/wlan0.network to set a fixed IPv4 address.
Then:
9 sudo reboot
10 dmesg
11 journalctl
12 timedatectl
13 sudo apt install openbox xorg x11-xserver-utils xterm feh unclutter -y
14 sudo reboot
15 xinit
this is the console output from the last boot, showing the xserver error at the end.

What have i missed to do, or done wrong?
