</div>The first step is to install Ubuntu on it, you can follow this howto:<br>
<a href="https://wiki.ubuntu.com/Nexus7/Installation" target="_blank">https://wiki.ubuntu.com/Nexus7/Installation</a><br>
<br>
But I recommend following the procedure to install Multirom to have<br>
dual boot instead:<br>

The only downside is that it seems to interfere with Android system<br>
updates, so you need to upgrade your Android rom manually after that.<br>
<br>
Backup and be patient, it takes some time.<br>
<br>
When you have ubuntu running on the nexus, activate the<br>
on-scren-keyboard (small icon on the top bar), open the terminal,<br>
install ssh and connect to it. Become root and run this script:<br>r<br>
<br>
This will set some configs, install a bunch of packages including<br>
Sugar, and install some activities as well.<br>
<br>
There are some bugs (mainly in the journal) I'm working in, but it is<br>
already pretty usable. Please report your findings! :)<br>
<div class="im"><br>
> Does Ubuntu talk directly to the hardware?<br>
<br>
</div>Yes. The first part of the procedure installs ubuntu in the android<br>
storage space (a file containing a disk image with ubuntu inside). The<br>
bootloader then is able to run it instead of android by using kexec.<br>
This means there is no emulation, you use Ubuntu as if it was<br>
installed on the machine by itself, and no Android software runs<br>
alongside it.<br>

<br>
</div>There is a lot of variation between SOC's, in particular you will have<br>
to fight with the graphics support, the bootloader, the power<br>
management...<br>
A recent Linus rant on the topic:<a href="https://lkml.org/lkml/2013/9/9/562" target="_blank">https://lkml.org/lkml/2013/9/9/562</a><br>
"I hope that ARM SoC hardware designers all die in some incredibly<br>
painful accident"<br>
<br>
In any case with more or less effort we can make sugar work on any<br>
machine that already runs GNU/Linux. In the case of the nexus I<br>
understand Canonical and Google partnered to make it work as a<br>
development exercise. But new arm devices running<br>
standard-non-android-distros appear every day, and several platforms<br>
are already becoming popular, so it is a path worth exploring.<br>
