Never mind, I think I accomplished all the above. I intend to write a little tutorial for the missing pieces and commands I will post here.

That said it lightdm still fails and I am back to Ray.

The old file is removed and the modified file matches his instructions. I have done “sudo reboot” and a power off reboot.

Would your writeup be appropriate for some section of the manual?
Perhaps under Supplementary Hardware? or...?

[hpeer]

I don’t know. Maybe.

There really should be some intro to linux commands and syntax. I am having difficulty knowing what is a file vs command, basic actions, etc.

So maybe my write up would demonstrate where a stone dumb newbie will stumble? At least a small sample.

The language is, to me, a major stumbling block.

WTF is a “bash”? For example. I THINK it is a way to invoke an action but???

Someone says “remove” takes me an hour to figure out that is written as “rm”.

But keep in mind that my issues here are all Edatec monitor related. I think I see the advantage if buying a Pi5 with an integrated touch screen monitor, solves a bunch of issues. But the implementation is not smooth.

And that is a while ‘nother can of worms. Some other hardware supplier will have different mods?

Maybe a list of proven hardware and or necessary mods?

**** ton of work there to maintain that.

For me: not for a manual. This is a very specific issue. If somebody searches, this thread has the pointers.

Sorry,

I just couldn't resist.

Perhaps this is what you are looking for.

[hpeer]

Well, I need a kindle book.
And Amazon next day delivery is 2 weeks for us here.

And I’ve bought 2 Raspberry Pi books already that have stuff about Python and other but not Linux.

I am having a tough time finding a Kindle Linux book.

bash started as the default linux shell program and there is a "bash " command prompt, you can run bash "scripts"

[hpeer]

So, asking here, you have a “kernel” with the most basic instructions and just above that is a “shell” which runs scripts on the kernel?

So a “bash” command runs a script that works on the kernel to do something?

How many shells exist at one time? More than one?

In my mind “bash” is a noun, like a name. “Jeeves, bring me a G&T” of more succinctly “Bash, G&T.”

A "shell" is an interface where a human can type commands, run programs, etc. A "shell script" is a list of commands to run such that the human doesn't have to type them all, just the name of the script.

On windows, a Command Prompt is a shell, as is a PowerShell Prompt. In a command prompt window, a batch file (.bat) is a shell script, and a power shell script is a .ps1 file. So, on Windows, there are (at least) 2 types of shells that can be opened, and you can open as many of them as you need.

The same is true of Linux. Only more. There are dozens of shells to choose from on UNIX, each with a slightly different language. On UNIX, there was a shell named the Bourne shell. Since it wasn't open-source, when Linux came around an alternative was written, the Bourne again shell (bash). Bash is the default shell on Linux, but it can be changed. I used to work with an engineer who insisted on the ksh shell and all the systems he managed had ksh as the default.

The original Unix shell was “sh”. I believe everyone now uses bash. What many don’t know is that the heart of MacOS is actually BSD Unix. Apple is the keeper of BSD Unix (and it’s why their OS is superior ) and as my company always used FreeBSD in the data centers, a terminal window on the Mac still feels like a familiar home

You can just download whole offline Wikipedia for Kindle.

When you install BBN OS you can also put offline Wikipedia on it too if you have enough disk space (SSD).

[hpeer]

I did just find The Linux Command Line on Kindle, that appears a good start anyway.

[hpeer]

I now have BBN up and running. I really struggle with getting the code correct, no matter how hard I try.

I am still struggling with screen orientation and the touch screen.

I go to System Tools/Screen Configuration but that does not seem to work. I have tried orientation and touchscreens together and independently.

Also looking at Budgie Control Center/Displays.
Select Single Display. But all options (e.g. Orientation) remain greyed out.

A fellow on another thread with Pi4 had some trouble missing xorg??

Do I need to annoy Ray at Edatec again?

Shoot me a email to Public At Hpeer with the usual suffix and I will send you what I have written to date. Word if that works.

It is a primer for a complete Linux idiot to install OCPN on a Edatec Pi5.

Surely not for everyone. But for me, with ZERO linux, this is what I struggled with. Well, that and my typing. AND the insanely tiny font on the LXTerminal. I think that had a fair bit to do with my difficulties.

I would be curious how you view it.

The last I’ve received from Edatech was:
“The latest update, now we have normal touch functionality”.

So you would want to hear it straight from the horse's mouth and contact Edatec support again.
