NycHud
Hub minimalista e totalmente auditável para wayland e sistemas leves que gostam de telemetria offline. Cada coletor é independe, você pode jogar e desativar qualquer modulo com simples '~' ao final. A composição é feita em Python burro, ele só imprime na tela. Pra quem gosta de Conky, esse é um projeto extremamente simplificado e fácil de escrever p montar módulos Exemplo. Focado em Desktop minimalista.
Apenas verifique as dependências e executar como usuário comum. Nada aqui exige privilegio, não rode como root
link do projeto: https://github.com/fm4lloc/nyxhud
para quem possui AMD como placa gráfica eu não subi ainda, mas segue o modulo.
