Eu tenho dois monitores que costumavam executar dois aplicativos diferentes em cada um. Por exemplo.
- O monitor A deve executar o navegador chromium
- O monitor B deve executar outro navegador chromium
Isso deve ser executado após a inicialização do sistema.

another screen consist of different youtube link with same setup
O problema é que consigo fazer com que um monitor funcione com esta configuração. O que significa o seguinte:
Vídeo do YouTube sendo reproduzido no navegador chromium Um startx está funcionando, mas outro monitor parece estar em branco e o erro que está apresentando é:

Telas e monitores não são a mesma coisa.
Você está tentando iniciar um servidor X separado e exibir para cada monitor, não é isso que você deseja fazer.
Você deseja iniciar um servidor X com 1 monitor ( :0) e dois monitores ( :0.0e :0.1).
Você deve ter uma startxchamada para start up :0e o script deve iniciar os dois aplicativos, movendo um deles para a segunda tela com o --window-positionparâmetro.
Se seus monitores estiverem lado a lado e o primeiro tiver 1920x1080 com canto superior esquerdo de 0,0, o canto superior esquerdo do segundo monitor será 1920,0.

O que Darth disse. Além disso, em nosso xorg.confvocê se refere a monitor0(for screen0) e monitor1(for screen1), mas você só tem uma monitorseção definida e é monitor0.
Meu palpite é que o erro de nenhuma tela encontrada é porque o X está tentando encontrar, monitor1mas isso não existe.
