I've hit just one snag since installing knoppix on my hard disk, and I suspect it's because Knoppix autoconfigures xf86. My monitor is a little quirky and has a range of refresh rates different enough that I have to specify them myself. I've tried running XF86Config and I've tried editing the files manually, but everytime I restart the files are reverted to their default state. It's not a huge problem as the default refresh rate works at 1024x768, but I would enjoy being able to change resolutions any ideas?
