Hallo zusammen,
ich bin relativ neu hier im Forum angemeldet, lese aber schon lange mit. ☺ Ich bin froh, ein Teil dieser Gemeinschaft sein zu dürfen!
Ich hoffe, Ihr könnt mir helfen. In der Wasserwacht nutzen wir einen Ubuntu-Rechner mit zwei Monitoren. Die Alarm-App hat ein Webinterface. Das Vorgänger-Gerät war ein Raspberry-Pi → hier wurde mit XRANDR ein "virtuelles Display" über die zwei bestehenden Monitore erzeugt. Hierauf wurde dann die Google-Chrome-Instanz angezeigt. Das klappt leider mit Ubuntu nicht mehr - oder ich stelle mich einfach nur zu blöd an. Ich hoffe daher auf eure Unterstützung.
Hier noch ein paar Systeminformationen:
