Eu venho do linux de execução e normalmente há um vídeo ou algumas configurações de acpi que controlam o brilho da tela, mas no FreeBSD, não parece haver nada assim, então meu monitor está constantemente a 100% de brilho. Não deveria haver alguma maneira de diminuir o brilho através da interface acpi?
Posso obter algum suporte para diminuir o brilho da tela?
