Ah, it sure does. Thanks!

I also noticed that it's possible to get enough information to figure
out the entire configuration. Continuing on your snippet (but using
ipython of course):

 In [10]: m1 = s.get_monitor_geometry(0)
 In [11]: m1.x
 Out[11]: 1280
 In [12]: m1.y
 Out[12]: 0
 In [13]: m2 = s.get_monitor_geometry(1)
 In [14]: m2.x
 Out[14]: 0
 In [15]: m2.y
 Out[15]: 0
 In [16]: m2.width
 Out[16]: 1280
 In [17]: m2.height
 Out[17]: 1024

As you can see I have my first monitor to the right of my second :-)

Most people, I think, don't even know what a Rootkit is, so why should
they care about it?
