I don't see how his argument carries any validity whatsoever.
I have four monitors in a strange setup. A row with three, 18, 23 widescreen, 18. Then, above the 23 I have an identical 23, but it's upside down.
Needless to say, it's a tremendous struggle to get it all working in Linux, and it's pretty much automatic in Windows.

It's an interesting read, anyhow.
