[Lekensteyn posted](https://twitter.com/#!/lekensteyn/status/160060206003400704) about Bumblebee rewrite being available on the `testing` PPA and I am very eager to test. I am currently on:

```shell
% bumblebee --version
Bumblebee version 2.4.0~git65b382e

% uname -a
Linux stan-inspiron 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
```

so I am wondering [how do I](https://twitter.com/#!/StanAngeloff/status/160067456713506817) go about installing 3.x? Do I simply add the `testing` PPA and perform a `[dist-]upgrade`? Furthermore, once the installation is complete, where are the relevant configuration files in case I want to tinker with Bumblebee/`bbswitch`?

I am the sort of person who doesn't like legacy files hanging around, would it be best to `--purge` my current install and then install from `testing` PPA (following a reboot)?

```shell
% dpkg-query -s virtualgl
Version: 2.3.1-1~oneiricppa3

% dpkg-query -s nvidia-current
Version: 290.10-0ubuntu1~oneiric~xup1

% dpkg-query -s xserver-xorg-video-nouveau
Package `xserver-xorg-video-nouveau' is not installed and no info is available.
```
