Ok. To run programs as root on X11 you need to transfer X credentials to root. This can be
done by hand (eek!) or just use "sux". That package was was kicked on debian in

https://sources.debian.org/src/sux/ - but better get the original from here
http://fgouget.free.fr/sux/sux-readme.shtml - I've found it to be a very valuable
piece of software.
"sudo su" should do the same as "sudo bash". "su" should
work on a clean install, but it will refuse to work if you have no password set for root.
so the first thing on ubuntu is to do a "sudo passwd" :) Anyway,
"sudo" asks for your password, "su" for the root password.
What I have not understood yet: you can get root
access from terminal with
"su" or you have to use "sudo bash" ?
Thanks, Nik! I'm glad somebody is willing to explain this to me like I am a
child. I probably ought to have got this years and years ago, but since I
don't need it so much in a group setting, or office, I could put it off.
Some of this discussion has been superseded by another email, as they crossed
paths.
However, in answer to this point: When I open a terminal, type "sudo su", I
can enter my password, and then I am root. I can do whatever I want to my
system, no matter how ill-conceived and dangerous. However, I cannot use it
to launch gui programs, only to run some root commands, such as when I want
to run pkill to kill several processes all at once, because they relate to
something else that is running away. When I am done, I type exit, or I can even kill su
processes, rather than
waiting for permissions to expire.
But when I (was) try(ing) to run a gui program (for example, gufw), I would be
asked for my password, then told that it was incorrect. I have set my system
not to allow root logins. There is no separate admin apart from the present
author, although I cannot just do anything; I still must enter my password to
become su.
However, without having installed quite all the trinity-sudo packages, I was
denied root permissions, except in the shell, by running "sudo su".
Sorry for the tedious details, but I do want to get to the bottom of this
issue, even though it may be self-inflicted.
There are no tedious details. If things are unclear they must be addressed - and everybody
is free to ignore or give input at any time. Nowadays with that windows nomenclatura mixed
in ... well, some days ago there was athread on "how to all a file or folder or
directory thingie" on devuan :)
