I, too, would love to know. I have an hp ze4630us laptop that is less
than useful due to this very problem. The laptop is dual boot witn
WinXP and CentOS4. When I connect the external port to a projector and
boot CentOS4, the image displays fine, but as soon as X starts the
projector loses sync. With WinXP running, the projector works just

It's a real bummer to have to make a Linux presetation with WinXP
