.Dd February 8, 2010 .Dt ACPI_FUJITSU 4 .Os .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: d -ragged -offset indent .Cd "device acpi_fujitsu" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -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.
p 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: l -tag -width indent t Va hw.acpi.fujitsu.lcd_brightness Makes the LCD backlight brighter or dimmer. t Va hw.acpi.fujitsu.pointer_enable Enables or disables the internal mouse pointer. t Va hw.acpi.fujitsu.volume Controls the speaker volume. t Va hw.acpi.fujitsu.mute Mutes the speakers. .El
p 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
a /usr/local/sbin/acpi_oem_exec.sh script: d -literal -offset indent notify 10 { match "system" "ACPI"; match "subsystem" "FUJITSU"; action "/usr/local/sbin/acpi_oem_exec.sh $notify fujitsu"; }; .Ed
p A possible
a /usr/local/sbin/acpi_oem_exec.sh script might look like: d -literal -offset indent #!/bin/sh # if [ "$1" = "" -o "$2" = "" ] then echo "usage: $0 notify oem_name" exit 1 fi NOTIFY=`echo $1` LOGGER="logger" CALC="bc" BC_PRECOMMANDS="scale=2" ECHO="echo" CUT="cut" MAX_LCD_BRIGHTNESS=7 MAX_VOLUME=16 OEM=$2 DISPLAY_PIPE=/tmp/acpi_${OEM}_display case ${NOTIFY} in 0x00) LEVEL=`sysctl -n hw.acpi.${OEM}.mute` if [ "$LEVEL" = "1" ] then MESSAGE="volume muted" else MESSAGE="volume unmuted" fi ;; 0x01) LEVEL=`sysctl -n hw.acpi.${OEM}.pointer_enable` if [ "$LEVEL" = "1" ] then MESSAGE="pointer enabled" else MESSAGE="pointer disabled" fi ;; 0x02) LEVEL=`sysctl -n hw.acpi.${OEM}.lcd_brightness` PERCENT=`${ECHO} "${BC_PRECOMMANDS} ; \\ ${LEVEL} / ${MAX_LCD_BRIGHTNESS} * 100" |\\ ${CALC} | ${CUT} -d . -f 1` MESSAGE="brightness level ${PERCENT}%" ;; 0x03) LEVEL=`sysctl -n hw.acpi.${OEM}.volume` PERCENT=`${ECHO} "${BC_PRECOMMANDS} ; \\ ${LEVEL} / ${MAX_VOLUME} * 100" | \\ ${CALC} | ${CUT} -d . -f 1` MESSAGE="volume level ${PERCENT}%" ;; *) ;; esac ${LOGGER} ${MESSAGE} if [ -p ${DISPLAY_PIPE} ] then ${ECHO} ${MESSAGE} >> ${DISPLAY_PIPE} & fi exit 0 .Ed .Sh SEE ALSO .Xr acpi 4 , .Xr sysctl.conf 5 , .Xr devd 8 , .Xr sysctl 8 .Sh HISTORY The .Nm driver first appeared in .Fx 5.4 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Sean Bullington Aq Mt shegget@gmail.com , .An Anish Mistry Aq Mt mistry.7@osu.edu , and .An Marc Santcroos Aq Mt marks@ripe.net .
