Current x.org versions should be able to auto-detect the VertRefresh and HorizSync settings, as well as appropriate modelines. So I would comment out all such stuff from your xorg.conf file, and see if the autodetection will work. Probably the easiest way to do this will be: mv /etc/X11/xorg.conf /etc/X11/xorg.conf.save X -configure (follow the printed instructions for testing the generated config) mv /etc/X11/xorg.conf You may have to change /dev/mouse to /dev/input/mice in the generated config before it will work. Then you can diff the generated config with your old one, and see what settings you want/need to keep.
