Hewlett-Packard HP-UX X Window server
If the X Window server is started with a display number which is different to the default value :0, the configuration files /etc/X11/Xdisplay_number* should be created by copying the corresponding X0* files, for instance for the display name :1:
cd /etc/X11
cp X0devices X1devices
cp X0pointerkeys X1pointerkeys
cp X0screens X1screens
