The system works fine with twm, but checking Xorg.0.log, I see

glxinfo confirms that DRI is working, but I just want to confirm that the
2nd set of messages above are bogus.
At the moment, I'm on my netbook. Will try to remember to check
that when the bread is baked.
It's probably determined by whichever video driver you are using,
plus whatever Mesa is set up to do. I've gone back to twm, but my
messages did not change. For GLX I have:
[ 13996.541] (==) AIGLX enabled
and
[ 13996.892] (II) AIGLX: enabled GLX_MESA_copy_sub_buffer
[ 13996.892] (II) AIGLX: enabled GLX_ARB_create_context

Also, glamor does not get a mention in _this_ Xorg log, probably
because I've got hardware acceleration. I recall seeing it
mentioned in Xorg with qemu - until I disabled it because it reports
an error - and I'm sure my test machine (radeonsi) will also mention it.
I guess the only thing to say then is that nouveau/glamor and AIGLX are not
completely integrated with each other, if at all. I only have a total of 4
AIGLX messages in my log. The three above and
(==) AIGLX enabled
I tried disabling it to see what happens.
Section "Serverflags"
Option "AIGLX" "0"
EndSection
The error message went away and glxinfo still says I have direct rendering.
The messages are still a bit confusing though:
[ 13070.912] (**) Option "AIGLX" "0"
[ 13070.915] (**) AIGLX disabled
[ 13071.146] (II) AIGLX: Loaded and initialized swrast
