Depois de um pouco de trabalho, eu escrevi uma solução mais completa e mais fácil de usar do que a encontrada abaixo. Você pode baixar o programa no GitHub. Você também precisará instalar as dependências:
sudo apt install xdotool xprintidle
Resposta original
Depois que Jacob Vlijm me indicou um solução parcial , combinei uma versão modificada de seu roteiro com pedaços de cafeína e um pouco do meu próprio código e inventei um substituto para a cafeína.
Instruções

Verifique se os pacotes necessários estão instalados. Nota:
caffeine-plusé usado apenas para ícones. Se você não se importa com ícones adequados, você não precisa disso.sudo apt install caffeine-plus xprintidle xdotool -
Salve o script abaixo em algum lugar e torne-o executável.
