I do it all the time without ever using xhost. su to root (not 'su -') and you should be able to launch graphical apps. I use gparted a lot. I assume that you mean a console/terminal inside an X-session. BTW, it's pretty easy to change the logo in xdm, and I'll tell you if I can remember where the file is. That install is gone already. I didn't figure out how to change the words. Maybe it's another graphic. I was looking for text. Anyway, check out the .xpm files in /etc/X11/xpm (I think it's there and not /usr/share). fsmithred _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
