[Sussex] Could anyone help me with Multiarch please?

[Fay Zee]

Hi,


My installed distro is Debian Wheezy, I use aptitude package manager,  
and my new laptop has an AMD ATI Mobility Radeon HD 4200 Series  
graphics card.

I would like to run Blender 3D, but although Blender launches okay,  
the 3D part is missing.

Blender and other OpenGL programs work perfectly on my laptop under  
Knoppix 7.2.0 (32-bit), so I know that my goal to run Blender under  
64-bit Debian Wheezy is achievable.

On Debian Wheezy I have run:

# dpkg --add-architecture i386

followed by

# aptitude update

Researching on the Internet throws up old posts and a lot of confusion.

Which packages do I have to install now to get the 32bit OpenGL  
libraries onto my machine, and what is the exact command, please?

I have downloaded the AMD Catalyst™ Display Driver for the x86_64  
Mobility Radeon HD 4xxx Series from  
http://support.amd.com/en-us/download/desktop/legacy?product=Legacy2&os=Linux%20x86_64 but am not sure if it is  
needed?


Best regards,
Fay
