But, when I reboot the script doesn't work, any solution? It starts automatically but it takes it 3-70 minutes to start after my OS has completely booted, it sometimes starts only one GPU and sometimes it starts both, any insites on these matters?
I'm on Ubuntu 13.10, 2X290X with cgminer.
Also, if my account is password protected (I disabled it for the time being), will the reboot work or will it get stuck on the enter password to login screen?
Thank you for all your work

You're welcome. Sounds like you have most of it figured out now...
Your crontab is currently configured to run on the second minute of every hour. If you want it to run every 2 minutes you need a '*/2' instead of just '2'.
You won't need to enter any passwords.
