# cd /etc/dt/config # vi Xservers

The following example shows the Xservers configuration file modified for one Creator card and two Expert3D cards:
:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -dev /dev/fbs/ffb0 -dev /dev/fbs/ifb1 -dev /dev/fbs/ifb0 -nobanner
See "Multiview Ports" for information on configuring multiple Expert3D cards in a single system.
