33.Nd Fujitsu Brightness, Pointer, and Hotkeys
34.Sh SYNOPSIS
35.Cd "fujbp* at acpi?"
36.Cd "fujhk* at acpi?"
37.Sh DESCRIPTION
38Some Fujitsu laptops come with vendor-specific
39.Tn ACPI
40devices to manage the laptop hotkeys (such as the
41.Sq Eco
42button), and to control various built-in components (such as the display,
43the touchpad, and the speakers).
44The
45.Nm
46and
47.Ic fujhk
48drivers provide support, through these
49.Tn ACPI
50devices, for hotkeys, backlight on/off switch, brightness level control, and
51pointer on/off switch.
52.Pp
53The following
54.Xr sysctl 8
55read/write variables are provided (when hardware support is available):
56.Bl -tag -width hw.acpi.fujbp0.brightness -offset indent
57.It Va hw.acpi.fujbp0.brightness
58Brightness level (integer).
59.It Va hw.acpi.fujbp0.pointer
60Pointer switch state (boolean).
61.It Va hw.acpi.fujhk0.backlight
62Backlight switch state (boolean).
63.El
64.Pp
65Please note, however, that future versions of the drivers may remove these
66.Xr sysctl 8
67variables without prior notice.

89.Pp
90The
91.Xr sysctl 8
92variable
93.Va hw.acpi.fujbp0.pointer
94should be replaced by a platform-independent userland control.
