Folks,
I've managed to get a Macintosh PowerPC (6100/66) running as an LTSP client.
The server is an Athlon running Mandrake 8.1. One of the things done when
starting up an X client is to "fix" the keyboard by swapping the functions of
the Delete and BackSpace keys. Unless you've had to deal with this before,
it's a rather arcane piece of folklore: the functions of these two keys were
incorrectly defined when the X code was developed, and there are several
ways of fixing the problem. Mandrake has a script in the /etc/X11/xinit
directory called fixkeyboard that swaps the action associated with the two
keys, and this is done as part of the xinit processs.
In the fixkeyboard script, the keys are reassigned based on the keycodes for
a standard pc101 keyboard. These codes are not the same for the Mac keyboard,
and the issue is further compounded if the LTSP workstation user is allowed
to logon locally, for administrative chores, for instance. I have modified
the script to look at the value of the variable DISPLAY to check on two
things: whether the terminal is local (DISPLAY = :0.0) or remote (DISPLAY =
ws003.test.home:0.0) and where the session is coming from. (Some workstations
might be PCs and use the standard keyboard.)
I have modified my script, and attach it for folks who might need to deal
with a similar problem:

# NOTE: when opening an X11 session remotely the keyboard must match
# the one on the remote display; so we check if there is a keyboard
# configured for the particular display first.
