Pi-is-four is our new Raspberry Pi 4 that shall replace Xbcmcbuntu for browsing / downloading / ...

Information

• CPU is a armv8, but as raspbian is 32-bit, it is reported as a 32-bit armv7l [1]:

lscpu
# Architecture:        armv7l
# Byte Order:          Little Endian
# CPU(s):              4

• We need usual Debian ARM to get 64-bit apps running. But this may also not be as optimized as Raspbian.

Configuration

• Install Raspbian Buster 32-bit (2020-08-20-raspios-buster-armhf-full.zip) using imager_1.4_amd64.deb.
• Install NoMachine server (armv7 because 32-bit OS, also 64-bit is reported as not being optimized).

• Enable hardware acceleration in server settings.
• Add to /etc/NX/server/localhost/server.cfg [2]:

AvailableSessionTypes unix-remote,unix-console,unix-default,unix-application,shadow,unix-xsession-default,unix-gnome,unix-xdm,windows,physical-desktop

• Restart the server /etc/NX/nxserver --restart.

• Use static IP by editing /etc/dhcpcd.conf [3]:

+interface wlan0
+static ip_address=192.168.1.96/24
+#static ip6_address=fd51:42f8:caae:d92e::ff/64
+static routers=192.168.1.1
+static domain_name_servers=192.168.1.1 8.8.8.8 fd51:42f8:caae:d92e::1

• Enable ssh server. The simplest is to [4]:

# Either touch a file and reboot the device
sudo touch /boot/ssh
sudo reboot
# Or enable through systemd
sudo systemctl enable ssh
sudo systemctl start ssh

• Add to ~/.config/autostart/set_belgian_kbd.desktop:

[Desktop Entry]
Type=Application
Name=Set Belgian autostart
Comment=Set keyboard to Belgian layout
NoDisplay=true
Exec=sh -c '/usr/bin/setxkbmap be'

This should fix the wrong keyboard layout issue.

• Install Ratio Ghost, and add to autostart.
• Install Transmission, and add to autostart.

• Add custom launcher exe /usr/local/bin/transmission-gtk to set http_proxy to point to ratio ghost port.
• Enable remote connection.

Issues

• When booting headless, the session is not the same as the one we get when we boot with hdmi connected.
