To solve this problem, I only add the ppa repository of blueman, geting some latest version of it.
In karmic, the process of including this type of repository, now is easier. Only this steps to include and update:

<p>To solve this problem, I only add the ppa repository of blueman, geting some latest version of it.</p>
<p>In karmic, the process of including this type of repository, now is easier. Only this steps to include and update:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> add-apt-repository ppa:blueman<span style="color: #000000; font-weight: bold;">/</span>ppa

<span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> upgrade</pre></div></div>

<p>My bluetoth device is recognized in &#8220;lsusb&#8221; as:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;">lsusb
Bus 006 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle <span style="color: #7a0874; font-weight: bold;">&#40;</span>HCI mode<span style="color: #7a0874; font-weight: bold;">&#41;</span></pre></div></div>

<p>Yes, is the cheaper usb bluetoth dongle. <img src='http://www.gustavocaixeta.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>No evento de Software Livre do ano passado na Unesp, o TaQ mostrou essa gem (o railroad).</p>
<p>Hoje utilizei ela para gerar um diagrama rápido do meu projeto (não quis pegar a folha de papel na mochila ehehe).<br />
<span id="more-67"></span><br />
1) Entre no diretório do seu projeto via console</p>
<p>2) Instale a gem railroad</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> gem <span style="color: #c20cb9; font-weight: bold;">install</span> railroad  <span style="color: #660033;">--no-ri</span> <span style="color: #660033;">--no-rdoc</span></pre></div></div>

<p>3) Instale o pacote graphviz para poder converter o dot para png</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> graphviz</pre></div></div>

<p>4) Rode o comando para gerar o .dot</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;">railroad <span style="color: #660033;">-o</span> model.dot <span style="color: #660033;">-M</span></pre></div></div>

<p>5) Converta o .dot para .png</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;">dot <span style="color: #660033;">-Tpng</span> model.dot <span style="color: #000000; font-weight: bold;">&gt;</span> model.png</pre></div></div>

<p>Pronto, haverão 2 arquivos na raiz do seu projeto. Basta abrir o model.png e visualizar <img src='http://www.gustavocaixeta.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Após a instalação, praticamente tudo estava Ok.</p>
<p>- Vídeo Intel x3100 (1400&#215;900)</p>
<p>- Wireless Intel 4965AGN</p>
<p>- Som Intel  82801H (até teclas multimídia estavam funcionando, só não testei mic)</p>
<p>- Teclas de Brilho</p>
<p>Primeiro passo:</p>
<p>Baixar a lista de pacotes atualizada</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> update</pre></td></tr></table></div>

<p>Atualizar o sistema</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> upgrade</pre></td></tr></table></div>

<p>Instalar sensores para medir a temperatura do processador</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> lm-sensors</pre></td></tr></table></div>

<p>É necessário rodar o detector de sensores, para verificar quais sensores sua máquina possui. Basicamente a instalação é &#8220;Yes&#8221;, &#8220;Yes&#8221; e na ultima pergunta, ele pergunta se deseja inserir o &#8220;coretemp&#8221; no /etc/modules</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> sensors-detect</pre></td></tr></table></div>

<p>Depois de detectar os sensores e reiniciar a primeira vez, o comando sensors deve retornar a temperatura do CPU</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;">sensors</pre></td></tr></table></div>

<p>No xubuntu (xfce), eu instalo um programa para adicionar ao painel para acompanhar a temperatura.</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> xfce4-sensors-plugin</pre></td></tr></table></div>
