2.4.3.3. ...using multiple mice and keyboards with one display?

The default X server configuration will work with all USB pointer devices and keyboards plugged into the system. The devices will work in parallel; for example, if you have two mice, moving either one will move the onscreen pointer, and if you have two keyboards, typing on either will send characters to the display.

Most keyboards will be detected as soon as they are plugged in, but other keyboards will be detected only when the system starts. For example, I have a secondary French Canadian USB keyboard and a USB calculator/numeric keypad; the French Canadian keyboard is detected as soon as it is plugged in, but the numeric keypad must be plugged in during boot in order to be detected properly. Special features of advanced pointers (such as touchpads) will not be configured automatically unless those devices are plugged in when system-config-display is run.
