Here's more information:
I gave myself a "text-only" system, via the command: "systemctl set-default multi-user.target"
Using two Virtual Text consoles: /dev/tty3 (alt-f3), and /dev/tty4 (alt-f4).
alt-f3 does the command I wish to continue running ("play", but could be compiling a Linux Kernel). alt-f4 gathers information.
Music plays fine, when in alt-f3, but stops in alt-f4.
So, I do "ps axu" in alt-f4, to see what happens to the "play" command. "Status= "S1+"!
People say that you don't need a Graphical Environment with a Server. But what if you want to Multitask?
**** Test part 2: on Devuan Ascii.
First, install it! (I don't count my Virtualbox version, because it doesn't do justice to my Virtual Console tests)
Now, under Devuan, Music keeps running when I switch Console to alt-f4.
Now, if I do "ps axu" in alt-f4, I see "Status = SL+"
So what is the difference between S1+ and SL+?
Thanks for the kind help, so far.
