i have FuSi esprimo V5535 laptop and of course i had problems with the SiS 771/671 graphics stuff.

i used Antonio J. de Oliveira's great instructions from http://sites.google.com/site/easylinuxtipsproject/sis and got the laptop display working like a charm. but i can't get my external display to extend my desktop on it. it shows the same desktop i have on the laptop screen. i'm sure it's only xorg.conf settings, but being the newbie i am, i need some help with it. anyone? pretty please....
