Mi Lenovo T440s se inicia con el máximo brillo. Siguiendo este hilo he tratado de alterarlo rc.local
, pero esto no funciona.
Cuando ejecuto el comando cat /sys/class/backlight/acpi_video0/brightness
obtengo el resultado 851
. Luego bajo mi brillo manualmente a través de las teclas de acceso rápido y ejecuto el comando nuevamente, todavía se muestra 851
.
Esto me lleva a creer que no puedo controlar mi brillo de esta manera simplemente agregando un comando a rc.local
.
¿Hay algo más que pueda probar?
