I8kbuttons - Monitor the status of Fn-buttons on Dell Inspiron laptops.
The i8kbuttons daemon monitors the status of the two volume buttons of
the Inspiron 8000 and the corresponding Fn- combinations.
When a button is pressed the daemon runs the corresponding command
specified in the command-line options. By specifying the proper commnds
it is then possible to control the volume of the sound mixer or run any
other command you like.
It must be noted that although the program has default commands for the
various buttons there are no standard mixer command shipped with the
many Linux distributions which can change volume incrementally and
support the mute/restore function. The default commands must therefore
be overriden with specific commands depending on which mixer software
is installed. Example:
i8kbuttons -u "aumix -v +10" -d "aumix -v -10" -m "aumix -v 0"
-r 100 -v
The program accepts the following command-line options:
Verbose mode, show all commands executed.
-u, --up <command>
Specifies the command to be executed when the VolumeUp button is
-d, --down <command>
Specifies the command to be executed when the VolumeDown button
-m, --mute <command>
Specifies the command to be executed when the VolumeOn/Off
button is pressed.
-t, --timeout <milliseconds>
Specifies the interval in milliseconds at which the daemon
checks the button status. Useful values are in the range 50-200.
Default is 100.
-r, --repeat <milliseconds>
Specifies the autorepeat interval in milliseconds. Useful values
are in the range 100-1000. Default is 0, i.e. no autorepeat.
Autorepeat starts after an initial delay of 250 milliseconds.
This program can be used by normal users or started as daemon by an
init script. Under Debian GNU/Linux it is possible to start
automatically the daemon at boot by creating an /etc/default/i8kbuttons
configfile and setting the I8KBUTTONS_UP_CMD, I8KBUTTONS_DOWN_CMD and
I8KBUTTONS_MUTE_CMD variables with the command which must be executed
by the program. Note the the /etc/default/i8kbuttons configfile is not
installed by the i8kutils package because the program is usually run by
normal users. If you want to use it as daemon you must create the
config file yourself.
