Marijana, The "gf" device driver requires access to an X server. You would have to set your DISPLAY environmental variable to an X server, or virtual X server. When you run from a crontab, generally your DISPLAY variable is not set, and you may not have permission to contact the X server. You can use the "gif" device driver without an X server. Remove any old "gplt" process using the "cleanup -c" script, or the "kill" command, and check for old message queues still in use with the "ipcs" command. Remove old message queues with the "ipcrm" command.
