How to globally disable antialiasing in Ubuntu?

view story

http://askubuntu.com – I'm using Ubuntu 12.10 on a Samsung R710 laptop which is equipped with a NVIDIA GeForce 9600M GT. At the moment, proprietary driver v310.14 (nvidia-experimental) is installed. Since my second monitor runs on full HD resolution, I'd rather trade the antialiasing feature for increased performance. Is it possible to disable antialiasing completely for all applications without having to disable it in every single app? Thanks in advance for your suggestions! (HowTos)
