Hi, everybody i bought a new laptopt Gateway, core i3, intel video card. I've tested ubuntu and mandriva without good video results. I have installed Fedora 12, i'm using an external lcd samsung screen on the vga port, it works fine. My display properties shows two screen as well as the correct resolutions...the problem it that i can't use my latopt screen, i have tried different resolutions..but nothing. I can't use mi laptopt without an external screen. Even if i boot without my external screen, my laptopt screen goes black Could somebody give me some ideas about it?
Because the Intel core I3 is too new i couldn't find information over internet, mi lspci shows that the card is  an i915 based.
I have tried a lot of diferent things, but, i couldn't fix it.
Thank you
