My best guess is that the problem was due to a recent update to x11-base/xorg-server On both my systems it now requires USE="glamor". This may require changes to xorg.conf. On my main desktop, with no xorg.conf, X does the detection and configuration "auto-magically". The hot backup machine would have an old xorg.conf with old (i.e. wrong) settings for the updated xorg-server.
This has been the case for many years now. Anyway, better late than never :-P
You do sometimes need some custom settings though. This goes in seperate *.conf files now, which must be inside the /etc/X11/xorg.conf.d/ directory. Some packages can place a config file there automatically.
