FUJBP(4) FreeBSD Kernel Interfaces Manual FUJBP(4)
NAME
fujbp, fujhk - Fujitsu Brightness, Pointer, and Hotkeys
SYNOPSIS
fujbp* at acpi?
fujhk* at acpi?
DESCRIPTION
Some Fujitsu laptops come with vendor-specific ACPI devices to manage the
laptop hotkeys (such as the `Eco' button), and to control various built-
in components (such as the display, the touchpad, and the speakers). The
fujbp and fujhk drivers provide support, through these ACPI devices, for
hotkeys, backlight on/off switch, brightness level control, and pointer
on/off switch.
The following sysctl(8) read/write variables are provided (when hardware
support is available):
hw.acpi.fujbp0.brightness Brightness level (integer).
hw.acpi.fujbp0.pointer Pointer switch state (boolean).
hw.acpi.fujhk0.backlight Backlight switch state (boolean).
Please note, however, that future versions of the drivers may remove
these sysctl(8) variables without prior notice.

HISTORY
The fujbp and fujhk drivers appeared in NetBSD 6.0.

CAVEATS
Brightness level and backlight switch state should be controlled via
wsconsctl(8) instead of sysctl(8).
The sysctl(8) variable hw.acpi.fujbp0.pointer should be replaced by a
platform-independent userland control.
