Running a startup program in terminal with sudo

I need to run a python script in a terminal, myscript.py at startup (on Lubunt). This script requires root.

I've set up a .desktop file that runs the following command:

lxterminal --command="python /home/d/Jarvis/alarm.py && /bin/bash"

The terminal window opens at startup and runs the script, but then closes when the Python script returns an error (because it's not being run as root). When I change the Exec= to this...

lxterminal --command="sudo python /home/d/Jarvis/alarm.py && /bin/bash"

... (prefixing command with sudo) which works. However, the terminal opens on startup and displays the

[sudo] password for d:

prompt, requiring me to input my password. I would like the execution of the python script at startup to be completely automatic with no user interaction.

How can I accomplish this?

If you want it at login and not startup (as I don't see how LXTerminal can be opened without X server being up), you have to add an exception to the /etc/sudoers file so that you won't be prompted for your password.

To do this, run sudo visudo and then add the following:

<your username> ALL = NOPASSWD: /home/d/Jarvis/alarm.py

Make sure that you add this at the end of the file for this to work. I would also set the permissions of alarm.py to executable for this to work. So, do this to set it as executable:

chmod +x /home/d/Jarvis/alarm.py

Hope it helps!
