Try putting /usr/X11R6/bin/xloadimage -onroot -fullscreen /root/rad_at.gif
into a script IE:
vi rad.sh
#!/bin/ssh
/usr/X11R6/bin/xloadimage -onroot -fullscreen /root/rad_at.gif
then make your crontab like this:
26 * * * * /root/rad.sh
what I think is happening is that cron is executing the
/usr/X11R6/bin/xloadimage but is not passing the associated args.
you could also try quoteing the command IE:
26 * * * * "/usr/X11R6/bin/xloadimage -onroot -fullscreen/root/rad_at.gif"
