====== Install Specific Video Card Driver ======

As I'm using a W150HRW Clevo laptop equipped with an Nvidia GT555M video card, i'd like to have it's specific driver installed and used instead of "vesa". At first I though that [[https://wiki.debian.org/NvidiaGraphicsDrivers|this article on the Debian wiki]] would be my savior, but a little line at the end of the page indicated that, as the happy owner of an **Optimus** hardware, I should have a look at [[http://bumblebee-project.org/|the Bumblebee Project]]...

reading through those references will eventually lead you back to... the debian wiki you started from!\\
To be precise, you'll get back to [[https://wiki.debian.org/Bumblebee|the Debian wiki page about Bumblebee]], where you'll find installation instructions:

===== Identify Driver and Hardware =====

First, to know **<color slateblue>what driver is effectively in use</color>**:
<code>
> cat /var/log/Xorg.0.log | grep vesa
[  3620.066] 	vesa
[  3620.078] (II) LoadModule: "vesa"
[  3620.078] (II) Loading /usr/lib/xorg/modules/drivers/vesa_drv.so
[  3620.078] (II) Module vesa: vendor="X.Org Foundation"
[  3620.081] (II) VESA: driver for VESA chipsets: vesa
[  3620.174] (WW) Falling back to old probe method for vesa
</code>

Now to identify the **<color slateblue>type of GPU</color>** your system is equipped with:
<code>
> lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 08)
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF106 [GeForce GT 555M] [10de:0dce] (rev a1)
</code>

===== Install Bumblebee =====

As stated on the [[https://wiki.debian.org/Bumblebee|Debian wiki]]: "For Wheezy users, Bumblebee packages are available from wheezy-backports". This means we first need to add the backports in our sources. To keep the system as clean as possible, you may want to add a file inside **/etc/apt/sources.list.d/ **rather than editing the **sources.list** file.\\
Here we'll create the **other-sources.list** file, then update our package list:
<code>
> nano /etc/apt/other-source.list

ADD:
deb http://ftp.belnet.be/debian wheezy-backports main

> apt-get update 
</code>

We can now install the Nvidia driver from the backports:\\
**<color slateblue>To use the free, "nouveau" driver:</color>**
<code>
> apt-get -t wheezy-backports install bumblebee primus
</code>

**<color slateblue>To use the proprietary, "nvidia" driver:</color>**
<code>
> apt-get -t wheezy-backports install bumblebee-nvidia primus
</code>
