<h1>Raspberry Pi</h1>
|
|
|
|
This page is my personal reference/cheat sheet for Raspberry Pi
|
|
related topics.<p>
|
|
|
|
<h1>Raspbian Wheezy</h1>
|
|
|
|
<h2>Install the XFCE Desktop</h2>
|
|
|
|
To install XFCE to use it instead of the default LXDE.
|
|
|
|
<pre>$ sudo apt-get install task-xfce-desktop</pre>
|
|
|
|
<h2>XFCE for the TightVNC Server</h2>
|
|
|
|
After setting up TightVNC, you can configure it to load the XFCE desktop environment
|
|
by modifying your <code>~/.vnc/xstartup</code> file. Mine looks like this:
|
|
|
|
<pre>#!/bin/sh
|
|
|
|
xrdb $HOME/.Xresources
|
|
xsetroot -solid grey
|
|
export XXL_XMODMAP_DISABLE=1
|
|
/usr/bin/xfce4-session</pre>
|
|
|
|
<ul>
|
|
<li>Use <code>vncpasswd</code> to set a password.</li>
|
|
<li>Use <code>vncserver</code> to start a VNC server (defaults to display :1
|
|
for the first server)</li>
|
|
<li>Use <code>vncserver -kill :1</code> to kill a server.
|
|
</ul>
|
|
|
|
<h2>Pi User Groups</h2>
|
|
|
|
If you add other users to the system, you'll probably want them to be members of
|
|
all the groups the pi user is part of. So...
|
|
|
|
<ul>
|
|
<li>adm</li>
|
|
<li>dialout</li>
|
|
<li>cdrom</li>
|
|
<li>sudo</li>
|
|
<li>audio</li>
|
|
<li>video</li>
|
|
<li>plugdev</li>
|
|
<li>games</li>
|
|
<li>users</li>
|
|
<li>netdev</li>
|
|
<li>input</li>
|
|
</ul>
|
|
|
|
<pre>$ sudo usermod -a -G adm,dialout,cdrom,sudo,audio,video,plugdev,games,users,netdev,input <ins>kirsle</ins></pre>
|
|
|
|
<h2>Sound access for other users</h2>
|
|
|
|
If you add a second user to the system besides the default "pi" user, they don't
|
|
get access to the sound device by default - so for example, the XFCE Mixer applet
|
|
gives a gstreamer error.
|
|
|
|
To get the XFCE Mixer applet to work, make sure the gstreamer plugins are
|
|
installed.
|
|
|
|
<pre>$ sudo apt-get install gstreamer0.10-plugins</pre>
|
|
|
|
<h3>Method 1: audio user group</h3>
|
|
|
|
This is probably the preferred way. Make sure your alternate user is a member of
|
|
the <code>audio</code> group.
|
|
|
|
<h3>Method 2: Add your user to the ACL for /dev/snd</h3>
|
|
|
|
<pre>$ sudo setfacl -m u:<ins>kirsle</ins>:rw /dev/snd/*</pre>
|
|
|
|
You'll need to do this <em>before</em> starting the VNC server. If you've already
|
|
started one, shut it down and restart it.
