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

Gene,
it might be due to the fact that I'm no native speaker but - I have no
clue what you are trying to do. Can you elaborate a bit more staight
forward? Where does your workflow stop during the process? What are
the command lines you are using? Up to what point it works and where
does it stop? And what has gimp to do with that all?
Maybe others have more intuition with your description

Hi Gene!
you may want to add this line on your remote machines .bashrc:
xrdb -all -query|sed -e '\''s#[A-Z_]*BACKGROUND# gray90#'\'' -e
'\''s#[A-Z_]*FOREGROUND# Black#'\'' -e
'\''s#[A-Z_]*HIGHLIGHT#White#'\'' -e
'\''s#[A-Z_]*LOWLIGHT# Black#'\''|xrdb -merge;
This has to go in one line. It's just the part of the "alias"-line I sent
you ages ago to make linuxcnc work on TDE :-) This is the line as an alias:
alias linuxcnc='xrdb -all -query|sed -e '\''s#[A-Z_]*BACKGROUND#
gray90#'\'' -e '\''s#[A-Z_]*FOREGROUND# Black#'\'' -e
'\''s#[A-Z_]*HIGHLIGHT# White#'\'' -e
'\''s#[A-Z_]*LOWLIGHT# Black#'\''|xrdb -merge; linuxcnc'
Again, just one line :-)

XFCE I believe as I am looking at the mouse while its initializing after
my login on a reboot.
None of those machines have more than 2Gb of ram in them, so the X used
is usually "lightweight". 2 of them are D-525MW Atom powered intel
boards, which we found to have the lowest IRQ latency of the lot.
Unfortunately its discontinued but if you can find one on ebay, the
asking is about 4x what Intel sold it for 4 years back. The "bell"
curve on that board peaks at around 3 microseconds. Some highly rated,
and high priced boards are so poor in that regard that extra hardware
help has to be installed. The problem when running stepper motors via
cpu, aka with software stepping is that at say a 10 kilohertz step rate,
a 10% variation in the timing of the next pulse issued costs you 50% of
the motors power as it will fall behind, then be incapable of catching
up so it stalls. That usually equals a wrecked part, and/or broken
tooling.
So for the bigger, faster stuff, that usually is offloaded to a
programmable FPGA card which does the high speed stuff, leaving the main
thread to run at 1000 times a second, doing all the floating point
stuff. Those accessory cards can usually move the machine 3 to 5x
faster than the cpu itself can, depending on the available voltage for
the motor power. At the higher speeds, motor winding inductance limits
the current, and available torque. Below those speeds, the driver
regulates the current so you get full torque. So voltages north of 24,
on up to the 160 volt range in the bring money in little red wagons
category. Those are fast, meters a minute motions, accurate to .005mm
in the line they traverse while moving half a ton of machinery that
fast. If cutting metal at those speeds is wanted, 25 hp water cooled
30K rpm spindles are needed.
Thanks Nik.

I am dead in the water because I'd have to dress and walk across the back
yard & up the hill to get to the building where the machine is just to
test my code. At 2AM, doable without dressing, but the noise of the
doors will wake my lady. So I just say to heck with it and go find my
bed, not knowing if what I just wrote works or not. Being an 81 yop
diabetic, I am up at 2 or 3 hour intervals in the night anyway.
What are
the command lines you are using? Up to what point it works and where
does it stop? And what has gimp to do with that all?
Other than to prove the x remoting works, nothing.
Maybe others have more intuition with your
