[LINUX] 13 Things to Do After Installing Ubuntu 20.04 LTS
Here is a summary of the recommended basic settings after installing Ubuntu 20.04 LTS (the contents are slightly different from those of 19.10).
Change the folder name to English
If you install Linux in Japanese, not just Ubuntu, the folder name in your home will be in Japanese, which is a little inconvenient.
Press ** Ctrl + Alt + T ** to launch the terminal,
LANG=C xdg-user-dirs-gtk-update
When you execute this command, a window will be displayed. After clicking the ** Update Names ** button, log out and log in again, and the window will be displayed again. Check ** Do not show again ** this time. If you click the ** Leave old name ** button, the folder will be in English.
Extend the time it takes for the display to turn off automatically
By default, if you leave Ubuntu for 5 minutes, the display will automatically turn off, but 5 minutes is a bit short.
If you enter ** power ** on the activity screen, the item ** power ** will be displayed.
Click on it to display the settings window. Change the ** blank screen ** in that settings window to ** 15 minutes ** or ** not **.
Show the trash in the Dock
Starting with Ubuntu 19.10, you can display the Trash in the Dock.
gsettings set org.gnome.shell.extensions.dash-to-dock show-trash true
Click here for the undo command.
gsettings reset org.gnome.shell.extensions.dash-to-dock show-trash
Move the application display button in the Dock to the top
Starting with Ubuntu 19.10, you can move the button at the bottom of the Dock to the top.
gsettings set org.gnome.shell.extensions.dash-to-dock show-apps-at-top true
Click here for the undo command.
gsettings reset org.gnome.shell.extensions.dash-to-dock show-apps-at-top
Allows you to enter Japanese
Immediately after installing Ubuntu, I cannot enter Japanese even if I press the half-width / full-width key. Click ** ja ▼ ** on the top bar, then click ** Japanese (Mozc) A ** to select it, and you will be able to switch Japanese input with the half-width / full-width keys.
Allows you to create an empty file from the right-click menu
If you place a file in the template folder inside your home folder, you can create it from the file manager's right-click menu.
touch ~/Templates/Empty document
Disable the ability to automatically maximize windows
When you start an application, Ubuntu will automatically start in the maximized state if the window size of the application is set to a certain size relative to the screen size, so it is the maximum without permission. If you do not want to be converted, disable it.
gsettings set org.gnome.mutter auto-maximize false
Click here for the undo command.
gsettings reset org.gnome.mutter auto-maximize
Avoid three issues with Japanese display
Ubuntu 20.04 currently has three issues:
First, the lower part of the Japanese character string such as the calendar and plug-in dialog is hidden and not displayed.
Second, when switching windows with Alt + Tab, the window switcher may expand vertically.

sudo apt remove -y fonts-nt-ui-jp
sudo apt autoremove
Allows you to play videos and music
If you check "Graphics and Wi-Fi hardware and ~" when installing Ubuntu, the codec is already installed, but you can additionally install codecs for video and music playback.

During installation, the screen of the terminal will switch to ** ttf-mscorefonts-installer is set ** **, so
Press Tab to select ** OK **, press Enter to re-select the options, press Tab again to select ** Yes **, and press Enter to continue the installation.
