[xubuntu] Setting window positions with wmctrl topic

This is on Xubuntu 14.04.1 LTS

I'm trying to automate certain aspects of my work setup, where I use several different apps and want them distributed over my screen real estate in a certain way.

I've found wmctrl and some example scripts that use it. Unfortunately wmctrl is very erratic and will sometimes work and sometimes not, which is obviously very frustrating.

So I'm looking for help: Is there a way to make wmctrl work properly? Are there alternatives? What do others do in my situation?

Saving of Multiple Monitor Screen Positions topic

Is there a way for Ubuntu to save off the screen positions in a multiple monitor setup?

I am running VirtualBox with Guest Additions installed. I have three monitors. Everytime I run Ubuntu 14.04, the screen windows do not position themselves correctly. Ideally, I would like a way to save these positions off so that next time I run Ubuntu, they come up in the right order and position.
