--- Comment #7 from Graham Perrin <grahamperrin@gmail.com> ---
(In reply to Neel Chauhan from comment #6)

Thanks, is there any non-GNOME use case that benefits from DRI 2?=20

I assume that <https://wiki.freebsd.org/GraphicsOld/DRI3>; is stale but not =
yet
<https://wiki.freebsd.org/CategoryStale>; categorised as such.=20

What's the simplest possible concise explanation of preferring 2 instead of=
 3?=20

(I see <https://en.wikipedia.org/wiki/Direct_Rendering_Infrastructure#DRI3>=
 but
trying to interpret that in normal order, let alone in reverse (2 instead of
3), is quite mind-bending.)

<https://www.freebsd.org/cgi/man.cgi?query=3Dxorg.conf&sektion=3D5&manpath=
=3DFreeBSD-Ports#DRI_SECTION>
directs readers to <https://dri.freedesktop.org/>; but then (sorry) it's not
clear which path to take; <https://dri.freedesktop.org/wiki/CategoryFaq/>; i=
s a
scattering of things.=20

Here in Bugzilla is not the best place for explanations, so maybe someone c=
an
edit something temporarily into <https://wiki.freebsd.org/Graphics>; or
<https://wiki.freebsd.org/Gnome>; pending more formal edition into (I guess)
<https://www.freebsd.org/gnome/>.
