Something I haven't played with, yet. However, after hacking around in the hal file to get rid of a pin does not exist error, I am back to an error that is a showstopper for running it, on that machine, but sending the x display stuff back to this machine. Logged into "lathe" with an ssh -Y session, an attempt to run 'linuxcnc -l' stumbles over, and exists with this error: _tkinter.TclError: unknown color name "BACKGROUND" Shutting down and cleaning up LinuxCNC... I think we hacked up something in the environment on this machine to fix those two errors (there will also be an unknown color name "FOREGROUND" error to deal with when we define BACKGROUND) but that was pre-wheezy on this machine. Do you recall how to fix that? FWIW, other stuff that uses X Just Works(TM), like geany or synaptic-pkexec, have no such problem.
