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/.
+ /var/lib/systemd/backlight/. During
+ loading, if udev property
+ is not set to
+ false value, 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.
