I just went to a console, with X still running, and as root, I cannot execute an xterm, as a regular user (who ownes the current X session) if i export the display as localhost:0, my xterm command is displayed in the X environment as expedcted. When I try with a differnt user, who does not own the :0 session, then I get: Xlib: connection to "localhost:0.0" refused by server Xlib: No protocol specified xterm Xt error: Can't open display: localhost:0 --- So it kinda sounds like a permissions thing. You may have tried this, but as the user that the servlet is running under, start an X session, then try running "xhost + localhost". When my user 'pete' runs this from within my X session, then my user 'test' can successfully display an xterm on the user 'pete' 's X server. -- Pete Nesbitt, rhce -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
