I'm using a newly installed Linux Mint and attempting to develop with Sublime Text 3. 

* I've installed p4v, p4 and ST3.
* I've created a P4CONFIG in the workspace folder that contains the `P4PORT`, `P4CLIENT` and `P4USER` variables and their appropriate values.
* I've added the Perforce.sublime-settings files to my `~/.config/sublime-text-3/Packages/User` folder that contains the other ST3 plugin settings.
* The settings include `"perforce_auto_checkout_on_save": true`.
* I've gone to terminal in the relevant folder I am trying to edit and ran the `p4 info` command and it seems to recognize the server and workspace I am trying to access.

No matter what I do, I am still unable to login using the `Perforce: Login` command and the appropriate password. As a result, when I save, it doesn't check out the files.

Please help me get this working. I really want this to work.

Thanks
