Software is open source. Make as many copies as you desire.

No menu bar with root.

"I set a password for root "
"When I login as root, no menu bar"


Make your own menu bar

I often use FileManager as root

sudo passwd root

set password

ctrl+alt+F2

login root

ctrl+alt+t

pcmanfm

/usr/share/raspi-ui-overides/applications/

- copy file-manager to root desktop


"Simple answer is 'Don't do it.' "

Dougie

That is not a valid answer.

That is advice.



"Debian does NOT have a root login"
"No distribution allows root to use a GUI."

Not true

Check linux mint. I do it all of the time.

"there should be no need to ever login as root."

I bet you also do not root your phone.

How would you copy a file from one directory to another?

Do you use a terminal or a GUi ?

Fresh install of mediawiki

it saves LocalSettings.php in ~/Downloads/

It needs to go in /var/lib/mediawiki/

You can do it with a terminal

but is easier with FileManager

If you try to do it with FileManager

you do not have permission

how do you use sudo to call FileManager

do you drop to a terminal to call sudo filemanager

I am not sure this even works

or just run your mouse over to the FileManager icon

Wait, stupid pi does not have an icon with root


How do you edit a config file?

Probably use nano.

How would you use geany to edit LocalSettings.php

sudo passwd root

enter password

Change workspace ctl+alt+F2

login as root

startx

FileManager

change to directory

click on the file

open with geany

make edits

save



"why are you logging in as root?
On modern Linux/Unix systems generally the root user is disabled "

So, how does one enable it?

"it may be missing various configuration files
and these may need to be created. "

like what?

"Of course if you have a reason for logging in as root, "
"then there's no problem with that - "

It is the problem. Finding the files.

" the desktop is not designed to run as root."
"You might not like it, but it's how things are set up."

and how does one change the set up?

"there is no good reason to change this"

You own my computer ?

check

.config/.lxsession
