Greetings;

On wheezy, running the newest r14.0.2 TDE I think, from the looks of the 
update done recently.

I have several other machines, all running a wheezy sourced release, 
customized with a special pinned rtai patched kernel because the main 
application they run is linuxcnc.

But they are running, generally, a simple XFCE interface.  And that 
program runs as well as its configured to do, something I am in the 
middle of re-writing in an effort to fine tune the machines performance.

One of the things I like to do is configure check from this nice comfy 
office chair is by running it over an ssh -Y login from here.

But that has always been a problem child,  a puzzling one because neither 
machine has in its environment, a setting for colors called FORGROUND or 
BACKGROUND.

But its a showstopper, and only for linuxcnc, which contains tcl 
scripting that bails out of the program before the gui can be drawn on 
this screen.  Other programs which use x run just fine, at least the 
ones I have tried.  That includes gimp, but that machine has no gimp 
loadable files on it.

pasted from the login screen:

_tkinter.TclError: unknown color name "BACKGROUND"
Shutting down and cleaning up LinuxCNC...

If it ever gets past that, it will do the same for the FOREGROUND color.  
BTDT but this machine was running an  older ubuntu at the time.  And its 
been long enough since I hacked around it that today I haven't a clue 
what I did then.

Does anybody have any suggestions on how to deal with this?

FWIW, the "simulated machine" version of that software runs just fine on 
this machine.

Cheers, Gene Heskett
