I have an old graphics-card which needs the nvidia-96 drivers. But the drivers need xorg-video-abi-10 to be installed, and my version of Ubuntu (Precise) has (i think) an newer version, because that package is not available in the repos.
I need the graphics drivers for OpenGL programs like Google Earth, Blender, etc.
Is it safe to downgrade X or will it break other programs (like Unity 2D)? And if yes, where do I get the package from?
