Glad you figured something out! However, you will probably want to research a bit further. As a general rule, it's almost never correct to make a local configuration modification by editing a file in /usr . Files under /usr are usually owned by distribution packages and changes to them will not be preserved when the package is updated. So in this case, we can see: [adamw@adam tmp]$ rpm -qf /usr/share/X11/xkb/keycodes/evdev xkeyboard- config-2.18-1.fc25.noarch that file is owned by the xkeyboard-config package, and whenever that package gets an update, your edits to it will be overwritten. If you keep researching on xkb, you should find a way to make your changes in a file under /etc (where system-wide local configuration is stored, by convention) or your home directory (where user-specific location configuration is stored).
