0.6.4                                             25 Juli 2005                                            TPB(1)

Configuration File

The default values of tpb can be overridden using a configuration file. The priority of the
configuration options is:

• builtin defaults

• configuration in /etc/tpbrc

• configuration in $HOME/.tpbrc

• configuration in file given with '--config' command line option

• command line options

tpb searches for the file '~/.tpbrc'. The configuration consists of lines of the form:

# COMMENT

KEYWORD ARGUMENT # COMMENT

Keywords are:

NVRAM Should define the nvram device from where the information about the key states is read. Default
is to try /dev/nvram, followed by /dev/misc/nvram.

POLLTIME
Defines the delay between polls in microseconds. Default is 200000.

THINKPAD
String with command and options that should be executed when ThinkPad button is pressed. It is
possible to execute any program. By default no command is executed.

HOME String with command and options that should be executed when Home button is pressed (only
available on A and S series). By default no command is executed.

SEARCH String with command and options that should be executed when Search button is pressed (only
available on A and S series). By default no command is executed.

MAIL String with command and options that should be executed when Mail button is pressed(only
available on A and S series). By default no command is executed.

FAVORITES
String with command and options that should be executed when Favorites button is pressed (only
available on A series). By default no command is executed.

RELOAD String with command and options that should be executed when Reload button is pressed (only
available on A series). By default no command is executed.

ABORT String with command and options that should be executed when Abort button is pressed (only
available on A series). By default no command is executed.

BACKWARD
String with command and options that should be executed when Backward button is pressed (only
available on A series). By default no command is executed.

FORWARD String with command and options that should be executed when Forward button is pressed (only
available on A series). By default no command is executed.

FN String with command and options that should be executed when Fn button is pressed. This is only
triggered, when Fn is released again and it was not used for a key combination. By default no
command is executed.

CALLBACK
String with command and options that should be executed each button press and state change. tpb
passes an identifier as first argument and the new state as second argument to the callback. So
you can do fancy things :) By default no command is executed. Supported identifiers and states
are:

IDENTIFIER STATES/VALUE
thinkpad pressed
home pressed
search pressed
mail pressed
favorites pressed
reload pressed
abort pressed
backward pressed
forward pressed
fn pressed
zoom on, off
thinklight on, off
display lcd, crt, both
expand on, off
brightness PERCENT
volume PERCENT
mute on, off
ac_power connected, disconnected
powermgt_ac high, auto, manual
powermgt_battery high, auto, manual

MIXER Use OSS mixer to change volume and for mute/unmute. This should be use on models with no
hardware mixer (volume and mute buttons show no effect). R31 is reported to have no hardware
mixer. To use this you must enable write access to the NVRAM device (possibly dangerous).
Possible values are on and off. Default is off.

MIXERSTEPS
Defines how much steps should be available when using the OSS mixer. Default is 14. If another
number of steps is used, tpb needs write access to the nvram device.

MIXERDEV
Defines the mixer device to use for OSS mixer support. Default is /dev/mixer.

APM Some ThinkPads generate mouse and keyboard events or have a high CPU load when polling /proc/apm.
You may enable this, if you want the AC connected/AC disconnected messages. Default is off.

POWERMGT
The program apmiser (part of tpctl package) switches the power management mode according to the
needs of the user. This results in lots of changes displayed in OSD. To avoid this, the power
management messages can be turned off. Default is auto.

XEVENTS Some of the special keys generate X11 events instead of changing the nvram. TPB is able to grab
those keys and run an application. In general events are only grabbed for keys for which a
command is assigned or if the callback script is configured. However some people like to use the
X11 events through xmodmap or the like. This option turns off the grabbing of all events
regardless if they are configured or not. Affected keys are HOME, SEARCH, MAIL, FAVORITES,
RELOAD, ABORT, BACKWARD, FORWARD and FN. Default is on.

OSD Show on-screen display for volume, mute and brightness. Possible values are on and off. Default
is on.

OSDZOOM Specific switch for showing on-screen display for zoom button. Possible values are on and off.
Default is unset, follows the OSD option.

OSDTHINKLIGHT
Specific switch for showing on-screen display for thinklight button. Possible values are on and
off. Default is unset, follows the OSD option.

OSDDISPLAY
Specific switch for showing on-screen display for display output button. Possible values are on
and off. Default is unset, follows the OSD option.

OSDHVEXPANSION
Specific switch for showing on-screen display for HV expansion button. Possible values are on
and off. Default is unset, follows the OSD option.

OSDBRIGHTNESS
Specific switch for showing on-screen display for brightness buttons. Possible values are on and
off. Default is unset, follows the OSD option.

OSDVOLUME
Specific switch for showing on-screen display for ivolume and mute buttons. Possible values are
on and off. Default is unset, follows the OSD option.

OSDPOWERMGT
Specific switch for showing on-screen display for ipower management changes. Possible values are
on and off. Default is unset, follows the OSD option.

OSDFONT Defines the font for the on-screen display. You may use "xfontsel" to choose one. Default is
the default font of the xosd library.

OSDCOLOR
Defines the color of the on-screen display. You may use "xcolors" to choose one. Default is
BLUE.

OSDTIMEOUT
Defines how long (in seconds) the on-screen display is shown after the last keys was pressed.
Default is 3.

OSDOFFSET
For backward compatibility. Same as OSDVERTICAL.

OSDSHADOW
Defines the offset of the font shadow in pixels. Default is 2.

OSDSHADOWCOLOR
Defines the color of the shadow of the on-screen display. You may use "xcolors" to choose one.
Default is BLACK.

OSDOUTLINE
Defines the width of the font outline in pixels. Default is 1.

OSDOUTLINECOLOR
Defines the color of the outline of the on-screen display. You may use "xcolors" to choose one.
Default is BLACK.

OSDVERTICAL
Defines the offset from the top or bottom of the screen in pixels. Default is 25.

OSDHORIZONTAL
Defines the offset from the left or right of the screen in pixels. Only supported by xosd 2.0.0
and above. Default is 25.

OSDPOS Defines where the osd is shown. Possible values are top, middle and bottom. The value middle is
only supported by xosd 2.0.0 and above. Default is bottom.

OSDALIGN
Defines the alignment of the osd. Possible values are left, center and right. Default is left.

Description

       With  TPB  it  is possible to bind a program to the ThinkPad, Mail, Home and Search button.  TPB can also
       run a callback program on each state change with the changed state and the new state as options.   So  it
       is  possible  to trigger several actions on different events.  TPB  has a on-screen display (OSD) to show
       volume, mute, brightness and some other information.  Furthermore TPB supports a software mixer, as the R
       series ThinkPads have no hardware mixer to change the volume.

Example

       tpb --osd=off --verbose --thinkpad="xterm -T ntpctl -e ntpctl"

Name

       tpb - program to use the IBM ThinkPad (tm) special keys

Notes

       Requires NVRAM device /dev/nvram.  This must be enabled in your kernel.  Although the  device  file  must
       exist.  The device file could be created with ´mknod /dev/nvram c 10 144´

       This program was developed on a Thinkpad Model T21.
