I was having very slow firefox scrolling and terminal text- I fixed it by updating to 260.19.21 from https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

System: Ubuntu 10.10 x64 with 3 monitors on 2 Nvidia cards using Xinerama

If your xorg settings aren't saving after running the Nvidia X Server Settings program try running it using sudo (sudo nvidia-settings).
