Well... exactly the same problem. I have a Geforce4 MX440 and a Sony E200 monitor. Once I've started the X (which runs perfectly), I can't use the console (alt-F1, etc) anymore, although I can switch back to X graphic mode. It's impossible to use the virtual consoles because the screen is totaly blank. The monitor itself displays an error "out of scaning range". Should I change some configuration in XConfig or should I ask for support of nvidia people ?? Any suggestions ?
