I used to use gsettings set org.gnome.desktop.background show-desktop-icons false to remove desktop icons from Ubuntu 18.04. But this no longer works on Ubuntu 20.04. Why is it not working?
Edit
I don't want other tools that would help me achieve the goal. I just want to know why its not working.
This might be just one time observation but minimal installation took more time than the normal installation. Then I looked at the logs while installation, and observed that some software packages like libreoffice,Thunderbird, Transmission ... are being removed. So my question is
Does ubuntu-desktop minimal installation just installs all packages that the normal installation installs and then removes some?
If yes, why? why install them in the first place?
EDIT
Just to be clear:
"Minimal installation" is a new option in the Ubuntu 18.04 Desktop installer, not to be confused with the minimal ISO (see tag "ubuntu-minimal")
I wanted to check how a certain software reacts when I change my computer's date. But I could not change the system time to anything less than 1970. Why is that?
