I expect it's simply not knowing about the eselect mesa bit, and having 
something set wrong, originally.  It would have been interesting to see 
what the xorg log said before we started experimenting, as I suspect that 
we fixed it in two stages, either setting something else wrong before we 
found the first problem so fixing it didn't solve the entire problem, or 
having two misconfigured settings in the first place and it took getting 
them both correct to fix the problem.

FWIW, if you haven't already done so, you will probably want to enable 
eselect's tab-completion option, among others.  eselect bashcomp list will 
give you a *BIG* list (199 items long, here) of bash-completion command 
options you can activate if you use them on the command line.  Each login 
user can run eselect bashcomp and set their own prefs, so root doesn't 
have to have the same set of active bash-completions as your normal user, 
as someone (significant-other, whatever) else with a login on your 
computer, etc.

Tab-completion for commands like eselect make them **MUCH** easier to use 
effectively, just as tab-completion for filesystem paths makes them both 
much easier to use effectively, AND much easier to use without error.  If 
you tab-complete an rm command, you're MUCH less likely to typo and rm the 
wrong thing, and MUCH more likely to catch it if you do typo, due to the 
completion giving you something unexpected, before you actually do the 
removal!

With eselect tab completion enabled, it too becomes much easier to use 
effectively and without error. =:^)
