I'm getting no errors but my screen does not look right at all. Depending on configuration tweaks and different modes I get either: - a graphic screen with non-moving but incoherent colored lines and blocks - a graphic screen with moving colored snow - the power save mode - no signal What does each mean (what's wrong which makes it do that)? What can I try to resolve each? I have XFree86 4.2.0 installed from the Linux binaries on top of Red Hat 7.2 with the NVIDIA GeForce2 MX400 and a Gateway Flat Panel which is connected via DVI. Are there any gotchas I need to know about any of these? Thanks, Helen
