I am seeking after the same issue to get Blender working. A lot seems to have changed in Debain (

I was on fedora for 6 months) and I want to do the right thing without having to worry about massing my system up.
When i try:
apt-cache search nvidia-glx
I see:
nvidia-glx - NVIDIA binary XFree86 4.x driver
nvidia-glx-dev - NVIDIA binary XFree86 4.x / Xorg driver development files
nvidia-glx-ia32 - NVIDIA binary XFree86 4.x driver
nvidia-glx-legacy - NVIDIA binary XFree86 4.x driver (legacy version)
nvidia-glx-legacy-dev - NVIDIA binary XFree86 4.x driver development files
nvidia-glx-legacy-ia32 - NVIDIA binary XFree86 4.x / Xorg driver (legacy version)
nvidia-kernel-legacy-source - NVIDIA binary kernel module source (legacy version)
nvidia-kernel-source - NVIDIA binary kernel module source
I think that means that you have x.org and not x11 common and should we use:
nvidia-glx-legacy-ia32 - NVIDIA binary XFree86 4.x / Xorg driver
Can anyone tell us what to do?
I have installed AMD64 through net install and did a dist upgrade to sid.
