N900 Mission Control

This page aims to document the Mission Control interface on the Nokia N900, as several things have changed since earlier versions of Maemo and previous instructions for e.g. setting presence no longer work as expected.

It is actively a work in progress as of late July / early August 2010.

[edit] Mission Control on the N900

As discussed on the Free Maemo page, the Mission Control included on the N900 is not the open-source version from the Telepathy package, but is provided by the osso-mission-control package under a closed-source Nokia licence.

[edit] mc-tool

There is a commandline utility for interfacing with Mission Control, in the shape of mc-tool. mc-tool is not installed by default on the N900, but is available as part of the package libmissioncontrol-utils. The built-in help is very limited, so you may wish to read the manual from the Ubuntu site or consult the example scripts further down this page.

[edit] Set MSN (pecan) to stay offline when disconnected

Since MSN allows only one client connection at a time, signing into MSN from the N900 disconnects it on my desktop PC, and vice versa.

Pidgin on my desktop PC handles this gracefully by disabling the account until I manually connect it. msn-pecan, on the other hand, helpfully auto-reconnects on its own authority and fails to respect my disabling auto-connect via mc-tool; if the requested status remains as "available", it reconnects, and that disconnects Pidgin on my desktop again. Grr.

You need an instance of dbus-scripts on the session bus for this one (see instructions on the DbusScripts page), then you can do the following:

[edit] /etc/dbus-scripts.d/dbus-scripts-settings 

#:MSN (pecan) disconnected (session bus)
/usr/bin/offmsn * * org.freedesktop.DBus ReleaseName org.freedesktop.Telepathy.Connection.pecan.msn_pecan.*

[edit] /usr/bin/offmsn 

#!/bin/sh
# If we got disconnected from MSN (eg by signing in via Pidgin on desktop PC) then set it offline until further notice
mc-tool list | grep "pecan/msn" | awk {'print "mc-tool request "$1" offline"'} | sh

[edit] Set all SIP accounts online/offline

These scripts are intended to be run from DbusScripts when (for example) WiFi is disconnected, or use any of the various schedulers (e.g. Alarmed) to change your availability according to time of day. Also note that "sofiasip" matches the name of the telepathy plugin that handles SIP accounts and not a specific SIP provider, so the commands in this example will operate on all the SIP accounts in 'mc-tool list'.

[edit] /usr/bin/siponline 

#!/bin/sh
mc-tool list | grep "sofiasip" | awk {'print "mc-tool request "$1" online"'} | sh

[edit] /usr/bin/sipoffline 

#!/bin/sh
mc-tool list | grep "sofiasip" | awk {'print "mc-tool request "$1" offline"'} | sh

[edit] Manage telepathy IM connections interactively from CLI

[edit] /usr/bin/im-connections

Simple script that will allow you to individually control each account (you must update the LIST variable with your actual accounts (get the names from "mc-tool list") - and update the menu accordingly. Courtesy of http://themattreid.com 

#!/bin/sh
