Restore Original Login Screen on Ubuntu 20.04

On a fresh Ubuntu 20.04 installation, I installed Unity and lightdm. The login screen looks different, where we now have the option to select the desktop environment to use before logging in.

sudo apt install ubuntu-unity-desktop

I then decided to switch back to the default GNOME desktop by uninstalling Unity. However, the login screen does not go back to the original one that came with the fresh Ubuntu 20.04 installation even after restarting the computer.

sudo apt purge unity-session unity
sudo apt autoremove
sudo apt install ubuntu-session gdm3

How can we restore the original login screen in Ubuntu 20.04?

Why .deb packages never add desktop and start menu shortcuts, even if installed software is graphical UI only?

Sorry if it’s a lame question but why installing software from .deb package never seems to add any shortcuts to desktop and start menu, even if installed software is a graphical UI program?

For example, try installing Chrome on fresh Ubuntu 20.20. You go to official chrome page where it will point you to the latest .deb package. Great. You download and install the package. Perfect. But then what?

No shortcut on desktop, no icon in start menu and -if you happened to close the package installer window – you even have no clue where the software was installed.

Is this fundamentally impossible due to some technical limitations of the package manager or is it just laziness of package creators which don’t care about auto creating those launcher shortcuts on desktop?

I’ve just installed new Ubuntu, installed Chrome and was puzzled how counter-intuitive and user-unfriendly the whole process is. I had to 1) find where the stuff from .deb was physically installed 2) create launcher manually 3) assign an icon to the shortcut manually.

mouse and keyboard not working on Ubuntu 20.04

I’m sorry I’m new to Ubuntu so I’ll try be as descriptive as possible.
At the moment my mouse is working when plugged into a specific USB port on the back of my PC. However when I move it to another port it doesn’t work. If I plug my keyboard into this same USB port then the keyboard will work and the mouse won’t. I have my system on a dual boot at the moment and I know for a fact that both the mouse and keyboard do work, it’s only when I reach the login screen that I have issues with my keyboard/mouse. I have tried other solutions given on this site and elsewhere but they don’t seem to work.
Like I said I’m new to Ubuntu and Linux as a whole so I’m sorry if this is an obvious question.

Icon change on Desktop doesn’t effect/apply

When I want to change the icon from a shortcut or folder on Desktop the change doesn’t effect/apply on Desktop. When I navigate to $HOME/Desktop ($HOME/Schreibtisch in my way) the icon change effects but not on the Desktop itself.

OS version: 20.04 LTS

gnome-shell-extension-desktop-icons is installed.
