So I had the fun of repeatedly trying startx (a total of three times) and putting symlinks in /usr/lib to forward to the new version.
Everything is easy when you know how to do it, but that seems like a fairly avoidable PITA. If I was a greener FNG, I'd have been stymied.
So I gripe aloud: is there a cleaner way of knowing when a new library version is going to punk me, or is this just cost-of-doing-business?
That is all.
