Description mark_evans 1999-04-11 22:40:32 UTC
After login in as a user under X, and su to root printool, netcfg etc can find the X server from a terminal.

You must use xauth to add authority for root to your display. man xauth for more information.
Comment 2 Preston Brown 1999-04-12 20:31:59 UTC
hopefully, su will be modified to do xauth automatically via pam before release, but if not, you will have to use xauth manually.
Comment 3 Chris Siebenmann 1999-04-12 22:37:59 UTC
My workaround for this problem is to explicitly set a XAUTHORITY environment variable that points to my .Xauthority file. As long as one uses su instead of 'su -' (which would wipe out the environment) and as long as root can still read the file after su'ing (not always true in some NFS environments), this lets programs run after the su still have access to the right xauth data. A short-term workaround for RedHat might be to add something like this to their XDM and/or startx script environments.
