It's still the old solution with "xrdb", same that works on TDE :-) This is (still) in my ~/.xsessionrc : # LINUXCNC ( sleep 10 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 ) & Nik -- Please do not email me anything that you are not comfortable also sharing with the NSA.
