How to add a new user and switch to it? I've tried `adduser` and 'useradd` to create a new user, but when I try to switch to the new user `su NEWUSERNAME` nothing really changes, I'm still the root user. Even tried logging out and then back in as the newly created user, but that doesn't work either. I'm on a 'headless' RaspbianOS Orange Pi Plus, stuck with only the ability to use the 'root' account.

Hi, I had the same problem BryanFRitt was explaining.
Created a new user su into it, nothing happens
Even if I try to log in from the login screen it doesn't work. Also trying to go into a shell login (ctrl + alt + F1-6) freezes the board without any possibility to recover apart from reboot.

This is the response:
You need wait for a while.


@ALL
open a terminal and write:

  1. echo 32768 > /proc/sys/vm/mmap_min_addr
Copy code
or maybe if it does not work:
  1. echo 4096 > /proc/sys/vm/mmap_min_addr
Copy code

Now you can login with useraccount:
username: orangepi
password: orangepi
or
username:bananapi
password: bananapi

please confirm

Ok, tried myself and it worked.


question: but when I reboot it does not work anymore why?

response: please wait for a while ahhhh this is @steven

response from fritz:

To ensure that this change in value is retained even after a reboot
you have to create a configuration file etc/sysctl.d/mmap_min_addr.conf

how to do?

from a terminal with root permissions type:

  1. echo "vm.mmap_min_addr = 4096" >  /etc/sysctl.d/mmap_min_addr.conf
Copy code


or

  1. echo "vm.mmap_min_addr = 32768" >  /etc/sysctl.d/mmap_min_addr.conf
Copy code


depends on the value you want. but both values should work
reboot and check if value change is permanent with:
       
cat  /proc/sys/vm/mmap_min_addr


Well, I'm a little pissed off about how things are going here
This is my last post on this forum until new and working code appears!

Bye guys
