+.Sh DESCRIPTION
+Some Fujitsu laptops come with vendor-specific
+.Tn ACPI
+devices to manage the laptop hotkeys (such as the
+.Sq Eco
+button), and to control various built-in components (such as the display,
+the touchpad, and the speakers).
+The
+.Nm
+and
+.Ic fujhk
+drivers provide support, through these
+.Tn ACPI
+devices, for hotkeys, backlight on/off switch, brightness level control, and
+pointer on/off switch.
+.Pp
+The following
+.Xr sysctl 8
+read/write variables are provided (when hardware support is available):
+.Bl -tag -width hw.acpi.fujbp0.brightness -offset indent
+.It Va hw.acpi.fujbp0.brightness
+Brightness level (integer).
+.It Va hw.acpi.fujbp0.pointer
+Pointer switch state (boolean).
+.It Va hw.acpi.fujhk0.backlight
+Backlight switch state (boolean).
+.El

+Please note, however, that future versions of the drivers may remove these
+.Xr sysctl 8
+variables without prior notice.

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