Since azureues has to run in an Xsession, you can't run it from the crontab or at. The reason is that All x clients require that the DISPLAY variable be set in the environment. Since this is not set unless you log in to an actual Xsession (or you use ssh with port forwarding, or some other such arrangement), running it from cron or at is probably not possible. Once possible solution is start up a "dummy" display and then let your cron job display to that one, either by allowing anyone to display to the "dummy" display or by setting up the magic cookie, or whatever other mechanism you choose. -Roberto -- Roberto C.
