I'm relatively new to Raspberry (i.e. to Linux) and I'm experimenting to build a kiosk panel with touch functionality. Only chromium is running with a web app. I follow the most steps of this "howto": HOWTO: Boot your Raspberry Pi into a fullscreen browser kiosk. I change and comment some lines in the xinitrc file. Either because I did not understand them, because it was not working or because it was not needed.
Here is the content of my xinitrc file:
#!/bin/sh
while true; do
# Clean up previously running apps, gracefully at first then harshly
# fch: ich verstehe zwar nicht, wieso das nützlich sein soll. Aber wieso nicht. Wird wohl nicht schaden, ausser den Start etwas verzögern.
killall -TERM chromium 2>/dev/null;
killall -TERM matchbox-window-manager 2>/dev/null;
sleep 2;
killall -9 chromium 2>/dev/null;
killall -9 matchbox-window-manager 2>/dev/null;
# Clean out existing profile information
# fch: Wir lassen das. Nach jedem Start müssen die Dateien halt neu geladen werden. Das ist aber gut nach Updates
rm -rf /home/pi/.cache;
rm -rf /home/pi/.config;
rm -rf /home/pi/.pki;
# Generate the bare minimum to keep Chromium happy!
# fch: Braucht es das denn wirklich? Und wenn ja, warum?
# fch: In der orginalen Anleitung steht version -> 46. Ich habe Version 48 installiert. Muss ich das ändern?
mkdir -p /home/pi/.config/chromium/Default
sqlite3 /home/pi/.config/chromium/Default/Web\ Data "CREATE TABLE meta(key LONGVARCHAR NOT NULL UNIQUE PRIMARY KEY, value LONGVARCHAR); INSERT INTO meta VALUES('version','48'); CREATE TABLE keywords (foo INTEGER);";
# Disable DPMS / Screen blanking
# fch: na ja. Vorläufig soll der Display doch im Standby Modus gehen. Es ist ja kein richtigen "Kiosk", der ständig eingeschaltet sein soll.
#xset -dpms
#xset s off
# Reset the framebuffer's colour-depth
# fch: Keine Ahnung, für was das gut sein soll. Wir probieren mal ohne.
#fbset -depth $( cat /sys/module/*fb*/parameters/fbdepth );
# Hide the cursor (move it to the bottom-right, comment out if you want mouse interaction)
# fch: Natürlich brauchen wir den Cursor!
#xwit -root -warp $( cat /sys/module/*fb*/parameters/fbwidth ) $( cat /sys/module/*fb*/parameters/fbheight )
# Start the window manager (remove "-use_cursor no" if you actually want mouse interaction)
# fch: Natürlich brauchen wir den Cursor!
#matchbox-window-manager -use_titlebar no -use_cursor no &
matchbox-window-manager -use_titlebar no &
# Start the browser (See http://peter.sh/experiments/chromium-command-line-switches/)
#chromium --app=http://saturn.pi-system.ch
#fch: andere starten Chromium so:
chromium-browser --noerrdialogs --kiosk http://saturn.pi-system.ch
# auch mit --incognito
#matchbox-keyboard &
florence &
done;
7" HDMI Touch display is running great. But I don't get the virtual keyboard working. I try matchbox-keyboard and florence. I read florence is better, because it would handle auto hide. But it would be nice to see this keyboard on my screen... I expected, it would be started after chromium if I call it in the xinitrc file. But nothing happens.
I know, there is a possibility to implement a javascript keyboard in the webapp. But I would like to avoid this trick.
Thanks for hints.
