XF86Config

Hi!

What's the difference between XF86Config and XF86Config-4 in my mdk 9.0 system?

Thanks!

The answer is "no difference". Either file will work with XFree86 4.0 and later. However, when searching for its config file, the 4.0-and-later X server will look for XF86Config-4 in each search directory before it looks for XF86Config (per the XF86Config man page). This allows you to leave your existing XF86Config file alone and generate a completely new config file when upgrading from pre-4.0 versions to 4.0 or later. Other than the order in which they are searched on startup, there is no difference between the two.
If the question is regarding the difference in the config file *contents* between the pre-4.0 XFree86 config file and the 4.0-and-later file, then yes, there are some differences.
See the 4.0-and-later man page for XF86Config for details.
