Got tired of this problem with Nautilus, so looked for a way to uninstall it. Interestingly, even after uninstalling Nautilus, the desktop was still running by it. No desktop icons as before.
Don’t like Gdm3, never did, so installed Lightdm and Slick greeter. Still running Ubuntu, not gnome-session, as seen below…Ubuntu Wayland runs too.
Needed a flle manager, so installed Nemo 4.0.6 and set it to run the desktop.
Thanks to @mc3man, @YamiYukiSenpai, @manbutu for the Nemo install ideas, and the guy, who created Nemo.
Let’s see how it works out as 19.04 grows. Right now, I am not worrying about “take-away-all-user-options” madness or whether Ubuntu would find a way out of it. Going to keep this install until the first release day of 19.10 development daily.
