What to do after installing Ubuntu 20.04 of White Tutorial

Ubuntu 20.04 was released, which brought many new features and still brought many unaccustomed things, so after installing the system, a series of optimizations should be carried out.

1. Delete libreoffice

Although libreoffice is open source, but Java written out of office implementation efficiency is really not flattering, after installing the system decisively deleted

sudo apt-get remove libreoffice-common

2. Delete the basically unused self-contained software (it is too late to install it when using it)

sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install

sudo apt-get remove onboard deja-dup

In this way, the system is basically clean.

3. Install Vim

Actually, there is no integrated Vim artifact by default, so it can only be installed manually.

sudo apt-get install vim

4. Set the time to use UTC

sudo vim /etc/default/rcS 

Replace UTC=no with UTC=yes

5. Install Chrome

Download the latest installation files at https://dl. google. com/linux/direct/google-chrome-stable_current_amd64. deb.

And then

sudo apt-get install libappindicator1 libindicator7
sudo dpkg -i google-chrome-stable_current_amd64.deb 
sudo apt-get -f install

In this way, apt can install and update chrome browser in the future.

6. Install the Sogou input method

vim/etc/apt/sources. list. d/ubuntukylin. list file, adding apt source of ubuntu kylin

deb http://archive.ubuntukylin.com:10006/ubuntukylin trusty main

And then

sudo apt-get update
sudo apt-get install sogoupinyin

In this way, apt can install and update sogou input method.

7. Install WPS Office

At present, MS1 can't directly produce Office version of Linux, so we can only make do with WPS

sudo apt-get install wps-office 

8. Install Oracle Java

sudo add-apt-repository ppa:webupd8team/java 
sudo apt-get update 
sudo apt-get install oracle-java8-installer 

Since the system comes with OpenJDK, it will have residue after uninstalling OpenJDK, resulting in running

sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install

0

When the first line is not the version number of java, it will be the prompt of Picked up JAVA_TOOL_OPTIONS:-javaagent:/usr/share/java/jayatanaag. jar, which causes many scripts that detect the version number of java to run incorrectly, so it is necessary to manually clear the residues.

sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install

1

Delete the /usr/share/upstart/sessions/jayatana. conf file, and then run java-version after restarting, and there will be no Picked up JAVA_TOOL_OPTIONS:-javaagent:/usr/share/java/jayatanaag. jar prompt.

9. Install Sublime Text 3

12. Customize the DNS Server IP address for the DHCP network
sudo vim/etc/dhcp/dhclient. conf file, at line 21 # prepend domain-name-servers 127.0. 0.1; Add the following 2 lines using aliyun and 114 DNS to the next 1 line

sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install

CMake and Qt Creator are artifacts for developing C + + programs under Linux, and Ubuntu 20.04 has integrated the latest version of Qt Creator.

Use the following command to unzip the file to the current directory.
