In theory. It seems distro personalities typically require some form of 
deviation.

True, but it is related, and also required following each new installation. 
Two birds, one stone.

Unset it where....?

In Mageia 3:
No xserverrc file anywhere in /.
XDG_VTNR # matches vt # where startx was run, or 7 if session started via KDM 
running prior to startx.

:(

In Fedora 19:
/etc/X11/xinit/xserverrc last written in Feb. 2009 contains no such string 
XDG or VTNR.
XDG_VTNR # matches vt # where startx was run, or 7 if session started via KDM 
running prior to startx.

:-(

FWIW:
When troubleshooting X I run the script following in Konsole on session start 
to capture a summary of system and X configuration. I created it originally 
as a means of self-identifying configuration of fullscreen X session 
screenshots I commonly attach to bug reports.

# run this in X terminal
