I'm no native speaker, but I know what Gene is talking about :-)

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 :-)
