Hello: Following upgrading of amd64 wheezy, version 302.17 of nvidia is incompatible with software I was using for molecular dynamics on CPU-GPU. On the other hand, amd64 stable offers a version of nvidia that is too old for the above application. Question: is it possible within amd64 wheezy to have a previous version of nvidia? If yes, a generic guideline on how-to would be much appreciated. Thanks francesco pietra
