Well, the Ubuntu 12.04 installations were pretty much new; they were installed from an old image but were updated to v12.04.3 right away. I just installed Kubuntu 13.10 on the second machine too, this time without VMware, and it behaves properly like the other machine. I can't explain this in any way other than for whatever reason, Nvidia's driver doesn't seem to like to behave properly on the 3.2 kernel with this particular card installed.
