Which config file is the default (XF86Config or XF86Config-4) has something to do with which version drivers you are using. With RedHat 7.0 I had a ATI vid card that used the XFree86 v3.3.6 driver so it used the XF86Config config file. I used the same disks to install on a different machine, I don't remember what the vid card was but it used the XFree86 v4.0 driver so it used the XF86Config-4 file. Weird huh? I think that not all the drivers were updated when they reached version 4 so they include the older config file format for backwards compatibility reasons. There may be other reasons, this is just my personal experience.

Can't tell you why.... anyone know? If there any modeline entries in XF86config-4, that would explain why you are unable to toggle between screen resolutions, if you don't have any defined. About 3 hours of aggravation before I discovered I had been editing XF86Config, instead of -4 Kyle Faber EMR Data Services On Thursday 03 October 2002 07:53 am, Ed Skinner wrote: > When I use a projector with my RedHat 7.2 notebook, > the projected video wiggles in vertical bands.
