It is not clear to me what do you mean by 'this'?
I doubt the problem dealt with in this thread had anything to do with sulphur versus equo. It is rather an almost unavoidable consequence of upgrading so many packages at once.
I for once use exclusively the command line equo, and after a series of similar massive package upgrades earlier this month I ran into similarly frustrating problems with dysfunctional gdm. Having wasted two days in vain to track their source, I simply reinstalled gnome-base/gdm and that cured the problem.
