Im using Ubuntu 14.04 and am trying to use crontab and pulse eight's CEC HDMI adapter and program to automatically turn off/on my display before and after business hours. I have the player up and running just fine, but once I edit crontab with the command, then save and reboot the rvplayer does not start. I have uninstalled rvplayer, re-installed and it works again, but the installation wipes out everything in crontab folder like it never existed. The programs don't seem to want together. How can I fix this?
