/usr/lib/systemd/systemd-backlight load [backlight|leds]:DEVICE
Описание (Description)
systemd-backlight@.service is a service that restores the display
backlight brightness at early boot and saves it at shutdown. On
disk, the backlight brightness is stored in
/var/lib/systemd/backlight/. During loading, if the udev property
ID_BACKLIGHT_CLAMP
is not set to false, the brightness is clamped
to a value of at least 1 or 5% of maximum brightness, whichever
is greater. This restriction will be removed when the kernel
allows user space to reliably set a brightness value which does
not turn off the display.
Командная строка ядра (Kernel command line)
systemd-backlight understands the following kernel command line
parameter:
systemd.restore_state=
Takes a boolean argument. Defaults to "1". If "0", does not
restore the backlight settings on boot. However, settings
will still be stored on shutdown.
