I have just installed FC4 on a Dell GX150 that has an onboard Intel 815 chipset. X does work, however there are all vertical lines that flicker and it seems to be a lot jerkier than it should. I found on some forums to add the Option = "noaccel" to the device section of the xorg.conf file, however this hasn't fixed it. Has anyone else seen or fixed this problem? Cheers, Craig
