I have an Nvidia GeForce 7300 SE. It worked fine with the nvidia driver when I was using 10.10. When I upgraded to 12.04, the (nvidia-current) binary driver failed—I couldn't even get a login screen. The "nouveau" driver works okay, but the display is quite sluggish.
I've read about the fact that my GeForce is blacklisted (here and here). But, when I tried the suggested workaround of using nvidia-173, I discovered that it wouldn't install because of a failed dependency: xorg-video-abi-10 (Package not available). The "precise" nvidia-173 package page notes this (dependency bug?)
So, my real question: is there a GeForce 7300 SE workaround for 12.04?
