  The output from...

emerge -pv --changed-use --deep --update @world > log.txt 2>&1

...is attached, gzipped.  Problems with "Block".  My secondary machine
is about to undergo the python 3.6 to 3.7 upgrade if that means
anything.  I've tried the usual trick of unmerging eselect-opengl but
that didn't help.  A similar update went OK on my main machine.

The mesa ebuild blocks eselect-opengl if the libglvnd USE-flag is set.   If  you
want eselect-opengl, remove the libglvnd flag.

        libglvnd? (
                >=media-libs/libglvnd-1.2.0-r1[X?,${MULTILIB_USEDEP}]
                !app-eselect/eselect-opengl
        )
        !libglvnd? (
                >=app-eselect/eselect-opengl-1.3.0
        )

  Thank you very much.  I've got the update (156 packages) running now.
I had set "-libglvnd" in make.conf on my main machine, but only against
xorg-server on my secondary machine.  Setting "-libglvnd" in make.conf
solves the problem.

Only for now.
"Libglvnd" is scheduled to be removed as a USE flag.
I would definitely suggest to switch to having that one on before it becomes mandatory.

It has a lot of benefits over the eselect hack to be able to have multiple opengl implementations running.

  The reason I had originally turned it off was because when it first
showed up as a flag, I checked Google to find out what it was.  Almost
every hit on webforums was like...

Person 1 - Help; my "update world" dies
Person 2 - Turn off "libglvnd" in make.conf
Person 1 - Thank you; my update works fine now

  Add me to the list.  If this is to be a new default config setup, I'd
appreciate a news item about it, like the python 3.6 to 3.7 switchover.

Even if it  didn't  break  block  eselect-opengl  with  mesa,  it  is  generally
extraneous for most non-NVIDIA users. From [1]:

        libglvnd is a vendor-neutral dispatch layer for arbitrating  OpenGL  API
        calls  between  multiple  vendors.   It  allows  multiple  drivers  from
        different vendors to coexist on  the  same  filesystem,  and  determines
        which vendor to dispatch each API call to at runtime.

See bug [2] and commit  [3]  for  details  regarding  the  breakages  in  X  for
modern-NVIDIA users without libglvnd.

(Video drivers do not actually require an X server to be present, as unless  the
`nomodesetting` parameter is given to the kernel, they can be initialised  pre-X
to provide high-resolution TTYs.)

I actually had to enable this on my new laptop before it became stable to get the Nvidia chip and my external displays working.
I am actually happy with this as I don't have to keep changing the opengl setting anymore when I need 3D performance.

Reading this thread, I checked and I to have this USE flag turned
off/disabled/whatever.  I removed it from make.conf and commented out
everything else I found in /etc/portage and am checking to see what all
had to be rebuilt.  I figure I may as well change now while I have a
otherwise stable system, except for the sddm-helper chewing memory
problem, and get ahead of the curve.  ;-)  Using that grep -r trick
comes in handy.  Learned that from this list too. 

It's odd how following a thread that may not even affect you ends up
doing so.  :/

Just in case, this is what emerge spit out on my screen.

When the lbglvnd flag was introduced I remember I solved this issue by:

    # emerge --unmerge eselect-opengl
    # emerge -1qv mesa

After that, a simple update of @world rebuilt everything else on its own.

Personally, I had been waiting for libglvnd support for _a long time_.
This - and I mean GLVND in general - is something that should have come
to Linux many years ago, along with NVIDIAs PRIME render offloading.

10y ago I used to have an Optimus laptop with an Nvidia GPU and it was
an absolute hell to get it running, I remember writing tonnes of scripts
using VirtualGL and a dummy X server running on the Nvidia GPU. This was
before bumblebee.

Today, I still need this with an external GPU.

But now it takes 1 environment variable to offload to the other GPU!
GLVND literally made my Linux work experience a million times better.
I'm extatic.

My change went quite well here.  I removed the flag entry everywhere and
then did a emerge world, with the correct options of course.  I then
logged out, went to boot runlevel, reloaded the video drivers, went back
to default and logged in.  I can't tell any difference here video wise
tho. 

I did notice that my sddm problem is worse now.  It's worse now than it
was when it first started.  In just a few hours it is consuming over
4GBs of memory.  That is ridiculous to me.  It using more than Firefox,
both profiles, and any other software I have running.  I'm thinking
about looking for a alternative to sddm.  I switched to it a while back
but I don't like this memory hungry thing behaving this way.

I missed the whole thing you are having with sddm, I just checked it on my 
laptop and not seeing anything like that.
Will reply further in the sddm-thread if I have any ideas.

Ever tried "x11-misc/lightdm"?  Runs like a charm here ...

I googled and found it as a alternative.  It was next on my list.  It
might have been a temporary switch but the logging out and back in as
getting on my nerve.  My puter stays to busy for that sort of thing. 
Once a week after updates is plenty for me. 

Thanks for the idea tho.  It's my backup plan.  So far tho, sddm using
the exact same amount of memory it was when I first logged in. From ps:

It is precisely why I had to implement GLVND before it became stable (using 
external overlays even and manually adding patches)

My new laptop doesn't work at all with bumblebee, because the external display 
ports are connected to the nvidia-chip and not to the intel-chip.
If reverse-PRIME would be supported, I would be able to disable the nvidia-
chip during 80% of the time and only enable it when playing games.

What a lot of updates! I'd emerge @system first, which will either give
the error with fewer other packages around, or proceed smoothly means
@world has less clutter.

It looks like xorg-server is demanding the newer version, try adding
--exclude xorg-server.

That will not help; mesa is providing libglvnd, not xorg-server.
