It's not though, it's definitely a PCI 7500. I don't know if >that's significant. All Radeon hardware chipsets are AGP. The X server is reporting an AGP chip because a Radeon PCI is a PCI card with a Radeon AGP chip on it. AGP is an extension of PCI. When the chip is on a PCI card, the AGP features are merely nonexistant. Note that it is the _exact_ same chip on a Radeon PCI or AGP card. They are not distinguishable via PCI ID. >First, the screen running off the VGA port looks pretty sharp, except >that there are ghost lines moving off to the right for all vertical >lines displayed.

It's probably a generic driver timing issue with the specific display hardware you've got, or even driver generic. If it is a driver bug however, it is most likely unfixable except by someone with the same video card, monitor/panel and ATI docs. You might find the xfree86@xfree86.org list to be more helpful as this is likely a generic XFree86 issue than one specific to Red Hat Linux. Hope this helps. TTYL -- Mike A.
