How should I logout? (from 'root' acct > into new created standard 'user')

Hi guys, after instalation 4Mlinux v34.2 to PC hdd and restarts and setting root paswd and a few settings > then I've followed web-site original instructions to create standard new 'user' & paswd > and after that I should log-out from root and log-in into standard user.

Q1:
But how can I log-out from this root acct and get into 'user'?
The JWM start menu doesn't have logout button & using some commands did not help logout:

logoff
logout
session-logout
CTRL+D
exit
gnome-session-quit --force
gnome-session-save --kill
pkill -KILL -u root
sudo pkill -u root
sudo pkill -KILL -u root

Neither restart works - 4MLinux just restart & log straight into 'root' acct again & again ...
I used also the Menu > JWM exit > so it exit into black command screen > I used command logout > then try login again as 'user' > enter passw > controll command 'whoami' says 'user' > but it's not letting use command 'startx' - there's always answer:
killall: can't kill pid XXX: Operation not permited

Is there please any way how to do it? How to log in and use allways standard acct. 'user' instead of 'root' in 4MLinux.
Thank you.

Q2:
So it looks like I will have to wipe it out of my hdd and try to do clear reinstall.
What is the proper way to install & create 7 use acct. 'user'?
1. install linux with create root > set root > install all sw & everything settings as 'root' > then create 'user' acct > log into 'user' > use 'user'?
or
2. install linux with create root > set root > create 'user' acct. right away > log into 'user' > install all sw & everything settings as 'user' > use 'user'?
or
3. install linux with create root > set root > create 'user' acct right away > stay into 'root' > install all sw & everything setiings as 'root' > then log into 'user' > use 'user'?

Q3:
And how to make 4MLinux to start pc automatic into 'user' (not into 'root')?
