About your complains about keyboard/mouse in graphical interface (X-server), note it is normal especially in older systems, the config of those things in X-server are independent from the console stuff. In modern systems X-server config have changed a lot.
Also note, that many of those systems even if they start X-server, they are not made to use it, many are simple accessed remotely
