Hi,

My Broadwell laptop hasn't had working accelerated OpenGL since I
installed it.  It was using the llvmpipe, a software path.  Eventually
when I looked into it, it turned out that was because the
xf86-video-intel package was too old and disabled acceleration for my
chipset.  So I wrote an xorg updater, which uncovered about 62 package
updates.  There are in wip-xorg-server-1.18, or eventually will be once
the send-email git hook finishes running.

There are two notable commits, which I attach here for comment.  The
first adds the updater.  The last changes how the X server starts.
At some point in the X.org 1.17 development cycle, input modules started
shipping .conf snippets that were to go in an xorg.conf.d file.  These
snippets would register certain modules as providing the drivers for
certain classes of input devices, using a kind of pattern matching.
However with our setup, we didn't have one xorg.conf.d directory with
these files in it.  I experienced this problem as what I perceived to be
a video freeze, but in reality it was just that I had no keyboard or
mouse because no module volunteered to bind to my input devices.  So I
changed the X service to generate such a directory, like we do with dbus
and other things.  A proper solution would probably be to make Xorg
modules be "services" which provide extensions to the X server package,
but that's a problem for another day.
