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

|
.Sh CAVEATS
|
|
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
|
|
