My laptop is Lenovo T400, whose screen size is 14.1 inches and default resolution is 1440 x 900. My main OS is Ubuntu 10.10. The default font size on the display is somehow small, which might contribute to the fatigue of my eyes.

1. My previous laptop is Acer 5000, whose screen size is 15.4 inches and the default resolution is 1024 x 768. I like reading on my old laptop better than on my new one. Is it possible to change the setting of my new one to look like reading my old one? What are the parameters that control the font size? Are screen size, resolution part of them?

   In Windows, there are choices for font size, while in Ubuntu I haven't find out where I can change the setting and would like know if someone here knows about it.

2. I also wonder if I can use a separate bigger display (perhaps just like a desktop display) as the display of my laptop, in case I don't want to enlarge font size at the cost of sacrificing the amount of the content to display, and how I shall do it?

Thanks and regards!
