크롬에 로드된 웹사이트를 변경하려고 할 때 X 서버 또는 $DISPLAY 누락을 해결하는 방법

저는 라즈베리 사용이 처음이고 칠리파이 키오스크를 사용하여 라즈베리 파이에서 키오스크를 개발 중입니다. 아이디어는 Raspberry Pi가 부팅되면 Chromium 브라우저가 Apache 서버(localhost)의 페이지에서 시작된다는 것입니다. 다음 구성(.xsession)을 사용하여 이를 달성합니다.

#!/bin/bash

## Establece la variable de entorno DISPLAY para que los programas X11 sepan dónde mostrar su interfaz gráfica. En este caso, :0.0 indica que el servidor de visualización X11 local está en la pantalla 0.
export DISPLAY=:0.0

# Start cursor at the top-left corner, as opposed to the default of dead-center
# (so it doesn't accidentally trigger hover styles on elements on the page)
xdotool mousemove 0 0

# Set some useful X preferences
xset s off # don't activate screensaver
xset -dpms # disable DPMS (Energy Star) features.
xset s noblank # don't blank the video device

# Set X screen background: Unicornio
sudo nitrogen --set-centered background.png

# Hide cursor afer 5 seconds of inactivity
unclutter -idle 5 -root &

# Make sure Chromium profile is marked clean, even if it crashed

# Verifica si el archivo de preferencias de chromium existe: .config/chromium/Default/
if [ -f .config/chromium/Default/Preferences ]; then
    # Existe: cat .config/chromium/Default/Preferences (en la .5 existe este archivo)
    # jq procesa el json de preferencias y se cambian exit_type y exited_cleanly
    # Se redirige la salida del comando jq a .config/chromium/Default/Preferences-clean    
    cat .config/chromium/Default/Preferences \
        | jq '.profile.exit_type = "SessionEnded" | .profile.exited_cleanly = true' \
        > .config/chromium/Default/Preferences-clean
    # Se renombra el archivo eliminando la extension -clean del nombre del archivo
    mv .config/chromium/Default/Preferences{-clean,}
fi

# Remove notes of previous sessions, if any
# Busca y elimina cualquier archivo dentro del directorio .config/chromium/ cuyo nombre comience con "Last 
find .config/chromium/ -name "Last *" -exec rm {} +

# Get URL from file (if set)
URL=""

# no parece que exista en .5: /boot/chilipie_url.txt
if [ -f /boot/chilipie_url.txt ]; then
    URL="$(head -n 1 /boot/chilipie_url.txt)"
elif [ -f /home/pi/chilipie_url.txt ]; then
    # Extrae la primera linea
    URL="$(head -n 1 /home/pi/chilipie_url.txt)"
fi


if [ -n "$URL" ]; then
    # URL no vacia: Obtiene el numero de serie de la raspberry pi
    SERIAL="$(cat /proc/cpuinfo | grep Serial | cut -d ' ' -f 2 | xargs)" # Get serial number

    # Reemplaza la variable SERIAL en la URL (si está presente) con el número de serie del dispositivo: http://example.com/?serial=$SERIAL deberia cambiar por http://example.com/?serial=10000000f9f937b8
    URL="$(echo $URL | SERIAL=$SERIAL envsubst '$SERIAL')"
fi

# Start and detach Chromium
# http://peter.sh/experiments/chromium-command-line-switches/
# Note that under matchbox, starting in full-screen without a window size doesn't behave well when you try to exit full screen (see https://unix.stackexchange.com/q/273989)
chromium-browser \
  --start-fullscreen \
  --window-position=9000,9000 \
  --disable-infobars \
  --kiosk\
  --overscroll-history-navigation=0 \
  --check-for-update-interval=1 --simulate-critical-update \ $URL &
# See https://github.com/futurice/chilipie-kiosk/issues/99#issuecomment-597119842 for 
# the need for the fishy-sounding "--check-for-update-interval=1 
# --simulate-critical-update" switches; TODO: remove when not needed
 
# Hide Chromium while it's starting/loading the page
wid=`xdotool search --sync --onlyvisible --class chromium`
xdotool windowunmap $wid
sleep 10 # give the web page time to load
xdotool windowmap $wid

# Finally, switch process to our window manager
exec matchbox-window-manager -use_titlebar no

지금까지는 잘 작동하는 것 같습니다.

실행 시 표시된 로컬 웹사이트를 변경하고 google.es를 표시하려는 Java 코드가 있습니다.

            String url = "https://www.google.com/?hl=es";

            // Comando para abrir Chromium en modo kiosco con la URL de Google
            String command = "chromium-browser --start-fullscreen --kiosk --new-window --no-sandbox " + url;

            // Ejecutar el comando en el sistema operativo
            Process process = Runtime.getRuntime().exec(command);
            
            LogManager.getInstance().println(LogManager.INFO, "intenta ejecutar la llamada a google.es");

            
            // Capturar la salida de Chromium
            InputStream inputStream = process.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            
         // Capturar la salida de error de Chromium
            InputStream errorStream = process.getErrorStream();
            BufferedReader errorReader = new BufferedReader(new InputStreamReader(errorStream));

            
            String line = "";
            
            while ((line = reader.readLine()) != null) {
                LogManager.getInstance().println(LogManager.INFO, "Salida estándar: " + line);
            }
            
            while ((line = errorReader.readLine()) != null) {
                LogManager.getInstance().println(LogManager.ERROR, "Salida de error: " + line);
            }

그러나 항상 오류가 발생합니다.

[2099:2099:0322/164415.631324:ERROR:ozone_platform_x11.cc(243)] Missing X server or $DISPLAY
03/22/2024 16:44:15 --> ERROR: [2099:2099:0322/164415.631658:ERROR:env.cc(257)] The platform failed to initialize. Exiting.

사용자 pi를 사용하여 SSH를 통해 라즈베리 파이에 연결하고 있습니다. /etc/environment를 수정하고 DISPLAY=:0을 추가했습니다. /etc/environment.d/90qt-a11y.conf에서도 수행했습니다.

존재하다/etc/X11/Xwrapper.configallowed_users=anybody로 설정했습니다.

내가 달리면주인나는 가지고있다:

access control enabled, only authorized clients can connect
YES:localuser:pi

내 무지로 인해 모든 것이 괜찮아 보입니다.

누군가 이 오류를 해결하도록 도와주세요.
