I have this allusion that I can except that sometimes people get words mixed up, but then realize it effects me to the point that I must allude conversation with them.

In a long experience with Ubuntu (well, LUbuntu) I never had such a problem.
Unfortunately I don't know a workaround for that.

Apparently I haven't had the problem either.
Thanks so much. Somehow I've literally been typing my password for weeks without actually knowing it. I was one character off today and couldn't get it. Yes, I'm obviously senile and a savant at the same time, because I can type a password incorrectly for weeks then not know it.
OY!!

You are welcome and, for sure, not alone on that.
I keep typing wrong passwords at work, just because the company password policy is insane and, above all, I am an old dog.

You might be able to boot to single user. Generally CTL-X, at the boot screen, then add "single" to the kernel boot parameters.
Alternatively, get a Knoppix (or other) Live CD/DVD and boot from that. Mount the root partition from the laptop's hard drive, and blank the password in /etc/shadow
e.g from something like this:
k5054:$6$gVGCezrmD49p1H/a$S2YUlUknRaPHIjdskN6dQ1GJeZpxxg4hlnuCB68CO8ZgmGEmAQiYjn0wjc83bM8aGOaYTdprtva0rIRRGVLSu1:18108:0:99999:7::: to this
k5054::18108:0:99999:7:::
Save, reboot, change password when you get logged in.
Next, generate ssh-keys for your both your Desktop and Laptop, and do a ssh-copy-id between the two. You should now be able to ssh in either direction without a password. If you'd prefer to retain the security of a password, add a password when doing the ssh-keygen.
If you'd prefer not to hard-boot the laptop you might be able to CTL-ALT-DEL to trigger a reboot (or a tap on the power button might work too). If the "Vulcan Neck Pinch" doesn't work from a GUI screen, you should be able to get to a non-gui login using CTL-ALT-Fn. I'm not sure which virtual console Ubuntu uses. Fedora uses VT1, and other systems uses VT7 or VT5, so try F4 or F6.

So, PEBKAC, then?
It still might be worth generating some ssh keys (preferably an ed25519 key-type), and check you can ssh between machines using them. And you never know when a Live CD/DVD might be useful too, so it might be worth burning one and making sure you know how to boot from it. Or a USB stick, which is faster than an optical drive.

Yes, PEBKAC.
I will implement a process to handle this in the near future.
Hopefully before I get into that situation again.

It's nice to know that Ubuntu makes it really hard for the people who steal your laptop.

Grub usually gives you a few seconds to interrupt the normal boot and allows you to choose single user/emergency. I don't think you need a password from there, and can reset the root password. I would check, but my desktop (Ubuntu 19) has a hardware problem at the moment.
Also, (assuming it is allowing you to type in the password), could it be a problem with a key on your laptop keyboard - which is going to be hard to spot when entering a password. Can you plug in an external keyboard - or telnet/ssh from your desktop.

Thanks for admitting it. And, yes, I'm far stupider.

- Try another keyoard?
- Is there in linux something like Alt&<numkeypadasciicode> to enter a character?

Pogo said it best: We have met the enemy and it is us.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

There's something to that, I'm convinced of it.
I've had a number of Linux distributions on a laptop I swear sometimes refuses to accept my password even though I know, absolutely and positively, has been typed in correctly. Then I force a reboot and everything's fine, on the very first attempt.
Every once in a while it's the NumLock key. Being a laptop, it doesn't have a dedicated numeric keypad, and some keys (YUI/HJK/NM, I think) can be reused to enter digits. But when I get in the situation described above, more often than not, hitting NumLock doesn't make any difference. For a while, I had temporarily changed my password so it doesn't use any of those multi-use buttons...and hadn't encountered the problem. It could have been just a coincidence. It's never happened often enough for me to notice any particular pattern or become a predictable thing.
Same laptop ran various versions of Windows for years prior to that, without ever exhibiting this behavior.
