[Solved]How do I get systemd on Ubuntu 22.04.3, when using X-11 ?

Asked by Bernard Stafford

I have Ubuntu 22.04.3 currently.
$ lsb_release -a; uname -a; dpkg -l | grep ' linux-i'
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
Linux b3-VirtualBox 6.2.0-26-generic #26~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Jul 13 16:27:29 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

ii linux-image-generic-hwe-22.04 6.2.0.26.26~22.04.7 amd64 Generic Linux kernel image

I need systemd to run instances correctly with LXD for making instances of containers, according to Ubuntu discourse.
* On this system how do I get to and boot each time on systemd ?
* How do I make x11 boot every time ?
During boot their is no "Advanced feature" to initiate using systemd.
Boot goes directly to the OS then boots automatically.
Operating system is running in Virtual Box.
Found this as some kind of reference: ?

I forgot to:
lxc config set ubuntu-1804 limits.memory 500MB
b3@b3-VirtualBox:~$ lxc exec ubuntu-1804 bash
root@ubuntu-1804:~# free -m
Limit the memory usage for the LXD container.
 Systemd requirements must be irrelevant, works fine in wayland and x-11 with out using systemd.
