.Sh NAME
|
|
.Nm acpi_fujitsu
|
|
.Nd Fujitsu Laptop Extras
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device acpi_fujitsu"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
acpi_fujitsu_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver enables the ACPI-controlled buttons on Fujitsu notebooks.
|
|
The button events are sent to userspace via
|
|
.Xr devd 8 ,
|
|
and a
|
|
.Xr sysctl 8
|
|
interface is provided to simulate the hardware events.
|
|
.Pp
|
|
Using this driver, one can control the brightness of the display, the volume
|
|
of the speakers, and the internal (eraserhead) mouse pointer.
|
|
.Sh SYSCTL VARIABLES
|
|
These sysctls are currently implemented:
|
|
.Bl -tag -width indent
|
|
.It Va hw.acpi.fujitsu.lcd_brightness
|
|
Makes the LCD backlight brighter or dimmer.
|
|
.It Va hw.acpi.fujitsu.pointer_enable
|
|
Enables or disables the internal mouse pointer.
|
|
.It Va hw.acpi.fujitsu.volume
|
|
Controls the speaker volume.
|
|
.It Va hw.acpi.fujitsu.mute
|
|
Mutes the speakers.
|
|
.El
|
|
.Pp
|
|
Defaults for these sysctls can be set in
|
|
.Xr sysctl.conf 5 .
|
|
.Sh EXAMPLES
|
|
The following can be added to
|
|
.Xr devd.conf 5
|
|
in order to pass button events to a
|
|
.Pa /usr/local/sbin/acpi_oem_exec.sh
|
|
script:
|
|
.Bd -literal -offset indent
|
|
notify 10 {
|
|
match "system" "ACPI";
|
|
match "subsystem" "FUJITSU";
|
|
action "/usr/local/sbin/acpi_oem_exec.sh $notify fujitsu";
|
|
};
|
|
.Ed
|
|
.Pp
|
|
A possible
|
|
.Pa /usr/local/sbin/acpi_oem_exec.sh
|
|
script might look like:
