Well - - - - I have at least two different configurations right now.
One with the 4k and one without.

I've read about those - - - - just haven't found a good cogent guide to
creating
such. There are so many things that I'm trying to do that I worry about the
low
hanging fruit and what absolutely needs to get done. If I have an up time
of
6 months taking 3 minutes to type out 4 to 7 commands doesn't bug me. Now
when my uptime is measured in single digit hours - - - - - anything to do
with
login and setup bugs me!

Do you know of such a 'guide' (a how to on writing log in scripts. I'm
finding
that when I go looking for stuff that 90% of what the search engine drags
up
was current as of 2010 or earlier and I've been bitten enough times by
stuff
that's out dated - - - - don't need more of that joy!) ?

I gave ubuntu the heave ho when they chose to force updates one their
schedule.
Am finding that they also seem to think that their solutions always work -
- - - they
sure as crap didn't when I was looking for ideas for my system setup the
last time
I was digging (some time ago but Ubuntu's arrogance as only increased so I
now
mostly avoid them except where they do something well (kernel supply is one
interesting exception!).

Outdated instructions - - - - nvidia sure as stink no longer supports
multi-gpu systems!
They want you to buy pro gear to do that - - - - have you checked the
pricing on that stuff.

I originally used xorg and a pure x11 setup but that's a tough way to do
things and
today xrandr works very well and then thirdly see up two.

It was actually the ArchWiki pages on multihead and multi-gpu setups that
helped
me when I was setting up. I would suggest that the instructions are at
least mostly
out of date and I would advise using the pages only for ideas and not for
actual method.

Simpler solution - - - use xrandr.

My first statment if I want to set up all 5 monitors is
$ xrandr --fb 7680x3000

That gives me a large screen and then I place the monitors within that
space.

would be useful advice - - - if it were 2014 or so - - - - using Xorg is,
if not deprecated,
should be - - imo.

I shouldn't have to spend more $$$$ .

The issue is that nouveau doesn't really or hasn't finished getting hdmi
2.0 working.
There may be reasons due to nvidia - - - - I am not in the know.
Just know that as of kernel 5.10.46 things are NOT working well!

You went to a lot of work trying to find ideas - - - greatly appreciated.
There is far too much advice on linux that is quite dated and when it comes
to gpus
its a real big issue. Some places - - - no biggie - - - but for gpus - - -
- not so.

Thanks for the help and ideas.

(Hoping you'll take my comments as information as to why something that
seems like a good idea
- - - well - - - if just ain't! rather than just as criticism.)
