AaiiYup, thats me.  And yes. I now have control over the fonts used in kmail.

And the simulated Linuxcnc I find, in the uspace version, runs well on a 
non-prempt AMD64 kernel.  Latency figures are of course astronomically 
horrible so one could never ever run even a servo controlled machine with it 
safely, but it serves to proof-read and execute cutting electronic air, the 
gcode I write just fine.  That was the point. :) However I hadn't tried it 
since installing TDE, and it now fails:

LinuxCNC terminated with an error.  You can find more information in the log:
    /home/gene/linuxcnc_debug.txt
and
    /home/gene/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal

So how do I fix this Unknown color problem?

Cheers, Gene Heskett
