That is your problem: You have configured sudo to allow you to run
i3exit as root.

But you don't. You run i3exit as yourself (without sudo), and IT then
uses "sudo pm-suspend" (and others).

Two possible ways forward:

- Call it using "sudo i3exit" and remove the calls to sudo from inside
  the script

- Call it as yourself (= just "i3exit") and give yourself the
  privileges to run "reboot", "halt" and others as sudo.

Hope this helps
