I thought this would be something python-people are familiar with, after
all idle is a Python IDE and running it as a root sometimes is necessary.
Anyway,
I tried out your suggestion but it didn't work, however googling the line
you suggested brought me close to a solution:
the following command does the trick:
xhost +local:root 

unfortunately putting it in ~/.bash_profile doesn't make it work
automatically
after booting, neither does putting it in ~/.xsession, in ~/.xinitrc nor
in an autostart-file in ~/.config/openbox/ 
putting it in .bashrc does work _after_ opening a terminal which isn't
very nice.

thanks and kind regards,
