I already knew that .Xauthority was in ~/, but I double-confirmed it with the echo command. Then I removed the leading $, and now I get No protocol specified Unable to init server: Could not connect: Connection refused gxmessage: unable to initialize GTK I posted about this on Ubuntu forums and someone suggested that I needed to add 'export DISPLAY=:0' before the rsync command, so I tried it, and then I added 'export XAUTHORITY=/home/jjj/.Xauthority' as well, but I still get the error message as above. Here is the current incarnation of my script: #!/bin/bash export DISPLAY=:0 export XAUTHORITY=/home/jjj/.Xauthority TS=`date` rsync -avx --delete /home/jjj/ /media/jjj/Data/JJJ gxmessage "Hello world" And, as always, if I run the script myself the message always pops up as expected. _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
