1) Franceso seems to have given himself the idea, long ago, that the presence of 32-bit code on an AMD64 machine is detrimental to performance (it's not) 2) On AMD64 Debian, the closed source (3D-enabled) "nvidia-glx" package is 64-bit only. 32-bit libraries are contained within a second package, "nvidia-glx-ia32" which you may or may not decide to install. 3) The "open source" driver is one you already have - xserver-xorg-video-nv package, which is generally pulled in when one installs X.org > On 12/18/06, Francesco Pietra <[EMAIL PROTECTED]> wrote: > > > > --- "Brian R.
