When using KMS, the screen defaults to a refresh rate of 60Hz. Once I log into my graphical session I can change it, but when I'm on a console it stays at 60Hz. Problem is that the old LCD I'm using on that particular machine does not like anything other than its default of 75Hz when using the native resolution, so I get a lot of distortion and noise on the display. Is there any way of changing the refresh rate.
