Eu vim rodando Linux e normalmente há um vídeo ou algumas configurações de acpi que controlam o brilho da tela, mas no FreeBSD, não parece haver nada parecido com isso, então meu monitor está constantemente com 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?

Tive dificuldades com o brilho no Dell L702X com Nvidia GT550M. Você pode ver o que encontrei emeste tópico (link). Talvez algumas dessas coisas funcionem para você.

Não consegui usar xbacklight(1)(ou ativar as teclas de controle de brilho), mas encontrei algumas outras maneiras de alterar o brilho:

  • xrandr(1)

Graças aesta postagem (link)Consegui alterar o brilho do monitor externo usando o xrandr. O comando fica assim:

    xrandr --output HDMI-0 --brightness 0.9

O valor padrão parece ser 1.

  • redshift(1)

    Redshift é um software que permite alterar a temperatura da tela. Possui -bopções -tque -gpodem ser úteis (veja man redshiftpara mais detalhes).
