 If you check the change log for xorg-x11-drv-intel you would see that....

 * Wed Oct 02 2013 Adam Jackson <ajax(a)redhat.com&gt; 2.21.15-4
 - Default to uxa again

 You, of course, could switch to sna by creating an xorg.conf which specifies it. 
Where is this change log.  Again it should be easy to find, but it seems not to be.
I would expect it to be inxorg-x11-drv-intel-2.99.917-28.20160929.fc26.src.rpmbut it's
not.

Similarly, a Google search for changelog "Default to uxa again"
yields this
pagehttp://pkgs.fedoraproject.org/xorg-x11-drv-intel.git/tree/xorg-x11-dr...
but trying to access this page produces
Page not found (404)

 Oh, and I believe if you looked in the Xorg.0.log it would tell you
what is being
 used more definitely than what I've assumed is an accurate changelog.  FWIW, I
don't
 use Intel Graphics Hardware. 
Again, it's not so easy.  There's nothing about sna or xua or acceleration in the
file.

The man page for intel(4) states that the default is sna.  What's correct, the
Changelog or the man page?  !!FOO!!
