The Gnome login screen normally shows a list of available users to log in as. For those who want to disable showing the user list, and manually type a username to login with, below I will show you how.
Open terminal by pressing Ctrl+Alt+T on keyboard, when it opens, run following commands one by one:
1. Run command to get access to root:
Type in your password (no visual feedback while typing) when it prompts and hit Enter.
2. In the terminal, run command to allow gdm to make connections to the X server:
3. Then switch to user gdm, which is required to run gsettings to configure gdm settings.
su gdm -l -s /bin/bash
Update May 2020: For Ubuntu 20.04, you may need to run one more command:
4. Finally hide user list from login screen using Gsettings:
gsettings set org.gnome.login-screen disable-user-list true
After that, restart your computer and enjoy!
How to Restore
To restore the change, open terminal and re-do previous steps, except running the last command with:
gsettings set org.gnome.login-screen disable-user-list false
The trash can icon is moved from left launcher to desktop icon since Ubuntu switched back to Gnome Desktop.
For those using files context menu or keyboard shortcut to delete file folders, and getting access to trash can via Files (nautilus file browser), the desktop icon is kinda useless and you may want to remove it.
You can easily remove (hide) the trash can desktop icon by doing following steps:
1. Open Ubuntu Software, search for and install Gnome Tweaks, a Gnome 3 desktop configuration tool.
2. Once installed, launch Gnome Tweaks and navigate to Desktop pane. There you can see the toggles to show or hide some desktop icons.
