Add the following line to your /etc/apt/sources.list: deb http://ftp.debian.org/debian/ unstable main contrib non-free You probably also want to create or add to /etc/apt/apt.conf the following: Apt { Default-Release "testing"; }; If your /etc/apt/sources.list has "wheezy" lines instead of testing, use wheezy instead. This will make sure you install packages from testing/wheezy by default and only install packages from other archives (unstable) when you explicitly say so. To install the nvidia package from unstable, do the following: aptitude install xserver-xorg-video-nvidia -t unstable This should pull in that package from unstable including it's dependencies. If it reports dependency issues, let aptitude offer you other suggestions until the issues are resolved. Another useful parameter for aptitude is "-s" which stands for simulate, so you can experiment as much as you want (also as normal user) without actually committing the changes. > And I don't want to use an unsupported release other than for testing > purposes. So, is it possible to downgrade to testing later on? instead of "-t unstable", do "-t testing" (or wheezy). If that doesn't work, add "/testing" to the package you want to downgrade, like xserver-xorg-video-nvidia/testing. You may have to supply all the package names you wish to downgrade (not sure why that is).
