This section explains how to uniquely refer to keyboards and pointing devices for later
reference in the XF86Config.Nserver file.
Adding USB Device Rules
Some systems will need rules added to the /etc/udev/udev.rules file to ensure that
the keyboard and mouse appear in a predictable location at each reboot. Follow these
steps to ensure that the rules are present:
1. Open the /etc/udev/udev.rules file in a text editor.
2. Search for the following two lines:
3. If the lines are already present, proceed to "Creating a Multi-Seat XF86Config File"
on page 146.
4. If the lines are not present, insert them before any existing KERNEL="event*"
lines.
Finding the Device Names
Follow these steps to find the device names for the keyboards and mice:
1. Look in the /dev/input/ directory for files beginning with "evkbd" and
"evmouse." For example:
evkbd-2-1:1.0
evkbd-2-2:1.0
evmouse-1-1:1.0
evmouse-1-2:1.0
2. Record these device names for use when editing the XF86Config.Nserver file, as
described in the next subsection, "Creating a Multi-Seat XF86Config File" on
page 137.
3. These device names include the USB path where the device is located. As long as the
device remains connected to the same USB port, these device names should remain
the same.
