No DVI output with Linux (Fedora) on T43p

[kenr]

I'm using a T43p with a port replicator and Fedora Core 4. I haven't been able to get my DVI monitor to work when booted with Linux. The attached VGA monitor works fine but the DVI monitor shows nothing. Fn-F7 doesn't cause the video to switch to the DVI port either.

Can someone offer some guidance in getting this to work.

It's been several months. I'm posting to bump this back to the top.
