So when an unmodified X server starts, it disables access to graphic cards for other X servers. Hence we have to modify XFree to make it possible more then one X server to run at the same time.</para>

<para>As USB devices are connecting in a tree form, you can really easy specify the way keyboard and mice devices are bound to a specified X display. You have to use one USB hub with number of ports equal(or bigger) to the number of the X displays, to this hub are connected smaller (2-4 port) hubs (or keyboards with integrated hub). To the first port of the smaller (integrated) hub are connected the keyboards, to the second the mice (in case there are free ports you can connect usb-audio devices to them :) ). This results in the following layout of the usb-id's in case the primary USB hub is the first USB device :</para>
|
||||
<note>
|
||||
<para>In the following explanations and examples I use for first device on the secondary(integrated) hub keyboard device because my keyboard is internally connected to the 1st port of the integrated hub. I assume this will apply for most of the keyboards with integrated hub, but in case the one you own uses different port you will have to make small adjustments.</para>
