Whenever I go to exit i3 a bar shows up on the top giving me the ability to to click
Yes, to exit, or
X to cancel.
What you want to do is edit your i3 conf, to find out where that is out you can use
$ i3-config-wizard The config file "/home/$USER/.config/i3/config" already exists. Exiting.
The line that sets up the exit command is in that file, and it was created by default
bindsym $mod+Shift+e exec "i3-nagbar -t warning -m 'You pressed the exit shortcut. Do you really want to exit i3? This will end your X session.' -b 'Yes, exit i3' 'i3-msg exit'"
You'll see the
i3-nagbar. That's the bar at the top responsible for nagging you. Just change that to go straight to the exit branch,
bindsym $mod+Shift+e exec i3-msg exit
And finally run
i3-msg reload to reload the configuration file.
