Another way to set up Linux,
Set up the automounter (autofs to access the fonts)
Add this line to /etc/auto.misc
fonts <fontserver IP Address>:/usr/fox/wp/fonts
This will automatically mounte the fonts under /misc/fonts whenever this
directory is referenced.
Modify /etc/X11/XF86Config-4 to add the extra font path
Section "Files"
FontPath "unix/:7100
FontPath "/misc/fonts"
EndSection
Modify /etc/inittab to change run level 5 from local display manager to remote
display manager
Change this
# xdm is now a separate service
x:5:respawn:/etc/X11/prefdm -nodaemon
to
# xdm is now a separate service
x:5:respawn:/usr/X11R6/bin/X -depth 8 -query <IPADDRESS of AW/WP>
This will work just like an Xterminal as recommended by Foxboro.
The whole display is hosted by the AW/WP and is configured using the Foxboro
Documentation about XTerminals.
Dual Screen Linux boxes work just fine in this mode as well.
