You can solve this problem using xhost. You have to run `xhost +' as the normal user so that your X display is open to everyone and then su as root.
But the better way is to export the X authorization cookies when you su. This is really simple if your authentication is based on PAM (which it should be unless it you are using a very old system). --/etc/pam.d/su--> session optional /lib/security/pam_xauth.so <---- The pam_xauth.so help is available at /usr/share/doc/pam-<version>/txts/README.pam_xauth (or something like that). I think post script versions are also available. -- M Rajsekar IIT Madras - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
