Hi<br><br>Do you start the accelerometer? It isn't enabled by default.<br><br>Don't know about GTK, but with Qt it goes like this:<br><pre class="prettyprint lang-h"><span class="typ">QDBusConnection</span><span class="pun">::</span><span class="pln">systemBus</span><span class="pun">().</span><span class="pln">call</span><span class="pun">(</span><span class="typ">QDBusMessage</span><span class="pun">::</span><span class="pln">createMethodCall</span><span class="pun">(</span><span class="pln">MCE_SERVICE</span><span class="pun">,</span><span class="pln"> MCE_REQUEST_PATH</span><span class="pun">,</span><span class="pln">MCE_REQUEST_IF</span><span class="pun">,</span><span class="pln"> MCE_ACCELEROMETER_ENABLE_REQ</span><span class="pun">));</span></pre>
And when exiting the application ... MCE_ACCELEROMETER_DISABLE_REQ<br><br>Timo<br><br><br>
