Hi Steve, First question is, what version of X are you running?
$ X --version If you are running XFree86 4.X the config file you need to look at is /etc/X11/XF86config-4. If you are running XFree86 3.X the config file you need to look at is /etc/X11/XF86config. If you are running XFree86 4.X you will find a log file /var/log/XFree86.0.log. Look inside this log file. Near the top you will find a line that tells you what configuration file X is using. (==) Using config file: "/etc/X11/XF86Config-4" or something similar. Some distributions have both Xfree86 3.X and 4.X installed at the same time. Check this out first then post the results back here.
