Always, when I want to add an application to startup, I use system monitor to find run-command and then add it to startup. But in Nitrotaks case the run-command is "/usr/bin/python/opt/nitro/bin/nitrotasks" and when I add it, doesn’t work. I've checked "nitrotasks" too. What do you suggest me ?
To add an application to start-up applications, just type start in Dash, and click on Startup Applications.
Once you click on it, and the new window opens, click on add to add you desired application.
A window will open asking for the apps info. Once you're done filling out all the information, click on Add, and you're done.
If you can start it from command line, try
which nitrotasks. It should show you the install path. Then follow Mitch's steps
