Li algumas perguntas sobre a execução de um aplicativo no segundo monitor, mas nenhuma das opções sugeridas funcionou para mim. Além disso, estou tentando executar aplicativos diferentes não apenas no segundo, mas também no terceiro e no quarto monitor.
Eu tentei
export DISPLAY=:0.1
export DISPLAY=:0.2
export DISPLAY=:0.3
export DISPLAY=:0.4
export DISPLAY=:1.1
export DISPLAY=:1.2
export DISPLAY=:1.3
export DISPLAY=:1.4
Mas nenhum deles funcionou. Apenas
export DISPLAY=:0
funciona para o monitor 1
No entanto, descobri que 'export DISPLAY: 0' é relativo ao monitor em que o mouse está localizado. Então, se o mouse está no monitor 4 e eu executo 'export DISPLAY =: 0' seguido por, digamos, ' eog image.jpg 'roda no mesmo monitor.
Aqui está o meu arquivo xorg.conf em execução. Talvez alguém possa obter alguma informação útil dela. Foi gerado por
