control-panel

Setup (Raspberry Pi 4)

1. Flash raspios; at various times, attempted ubuntu, ubuntu server, ubuntu mate, and arch arm; all froze or had package compatibility issues; raspios appears to be the best supported
2. Update and install system packages

• sudo apt update && sudo apt upgrade
• sudo apt install handbrake handbrake-cli vlc libdvdcss2
• sudo hostnamectl set-hostname <name>

3. Setup as access point

• if you get a persistent error in the Network Panel of the task bar that says, 'Set WiFi Country', you need to create two files in /etc/wpa_supplicant/ called wpa_supplicant-wlan0.conf and wpa_supplicant-wlan1.conf each with contents like:

  ctrl_interface=DIR=/var/run/wpa_supplicant
  GROUP=netdev
  update_config=1
  country=US
  
  network={
          ssid="<SSID>"
          psk="<password>"
  }
  

• setting up wlan0 as a local AP will also cause the network panel to show No wireless interfaces found (as of 2020-10-29); it will still work with nmcli though

4. Setup fair-winds repo

• mkdir ~/.ssh && ssh-keygen && cat id_rsa.pub
• copy and paste to github
• git clone git@github.com:danjenson/fair-winds.git
• python3 -m venv ~/.venv/v && source ~/.venv/v/bin/activate
• cd fair-winds && ./install-locally.sh
• add to end of ~/.bashrc
  • source ~/.venv/v/bin/activate
  • export PATH=~/.local/bin:$PATH
• pip3 show fair-winds | grep Location -> <path>
• sudo cp <path>/control_panel/control-panel.service /etc/systemd/system/
• sudo vim /etc/systemd/system/control-panel.service
  • replace <python-path> with the output of which python
  • replace <control-panel-path> with the output of which control-panel
    • note that the outputs of which <program> should be the same except the value after the last /
• systemctl enable control-panel.service

5. [Optional] open browser/control-panel

• set browser home to localhost:8000
• vim ~/.config/lxsession/LDXE-pi/autostart

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
#@xscreensaver -no-splash
point-rpi
@chromium-browser

Debugging

• useful script to have on pi in ~/update-fair-winds.sh:

  cd fair-winds \
  && git pull --rebase \
  && ./install-locally.sh \
  && sudo systemctl restart control-panel \
  && systemctl status control-panel
  

• if bluetooth is acting up
  • systemctl status bluetooth
    • if there are SAP errors
      • vim /etc/systemd/system/bluetooth.target.wants/bluetooth.service
        • ..../bluetoothd --noplugin=sap
    • new bthelper (2020-05-12)
      • wget https://raw.githubusercontent.com/RPi-Distro/pi-bluetooth/master/usr/bin/bthelper
      • chmod +755 bthelper && sudo cp bthelper /usr/bin
• if dvd playing is acting up:
  • sudo dpkg-reconfigure libdvd-pkg

Extra

• remap caps lock to control
  • sudo vim /etc/default/keyboard
    • XKBOPTIONS="ctrl:nocaps"
  • sudo dpkg-reconfigure keyboard-configuration
