I have a PC with Fedora 5 on it. When it boots, it appears that the screen resolution is too high for the monitor I'm using as vertical lines appear and a message appears stating "Input Out of Range". I have a 15" NEC Flatscreen (LCD 1560V). The system doesn't automatically change the resolution for me, so I'm not able to see the login screen to login to Fedora.
Is there a way to modify the resolution setting without booting into the operating system?
