You are trying to fix the problem without any knowledge of what the problem is. This is why I constantly tell people to slow down. The log you just posted
hits on multiple topics in one single braindump.

To break it down into 3 topics...

First, Go back to nvidia-390, there was never a reason to downgrade.

Second, boot errors about a VGA console are normal. The Nvidia module
complains, but it is a meaningless error and can be ignored.

Third, I don't think you ever told us what exactly you are trying to do with
your multi-monitor config. I remember a lot of confusion and chaos about
getting X started and using xorg.config files in your home directory (which does
not work, X doesn't load config files from $HOME..).

Since your driver packages are now FUBAR, run the following steps to get back
to a working display:
- Uninstall any nvidia driver packages on your system

Do I run nvidia-switch --remove, slackpkg remove nvidia-legacy340-driver ... (both driver and kernel), or all of the above?

And, do I need to restart at run level 3 to do these?

- reinstall the base distribution packages that were overwritten
slackpkg reinstall xorg-server libdrm mesa

- Make sure you DON'T have a file named /etc/X11/xorg.conf
- delete the nouveau blacklist file in /etc/modprobe.d/
- reboot

After you reset back to the sane defaults, you can explain to us what it is
you are trying to do and maybe someone can advise a path forward.

I'll give that a shot when time permits, possibly tomorrow.

Time permitted this afternoon.

I rebooted to run level 3.
I ran nvidia-switch --remove

I ran slackpkg remove nvidia-legacy390-driver ...
I ran slackpkg remove nvidia-legacy390-kernel ...
I ran slackpkg remove nvidia-legacy340-driver ...
I ran slackpkg remove nvidia-legacy340-kernel ...
All four completed, although the 390 kernel complained that some files were in use. I assume they were also there as part of the 340 package.

I deleted /etc/X11/xorg.conf, and a few backups with that name included.

I deleted the nouveau blacklist file from /etc/modprobe.d

Then I rebooted, or at least tried to.

I watched as the system shut itself down. But when I started it back up, I saw a little graphic in the upper left corner of my DVI monitor blink between Analog and Digital a few times, and then stop. No response to the keyboard. When trying to ssh in, I got the message:

dick@ENU-1:~$ ssh [email protected]
ssh: connect to host 192.168.0.134 port 22: No route to host

I can still boot from the install USB stick, which is what I expect I'll need to do next.

Recommendations on what else to do next?
