3. Upgrade Google Chrome

During the installation process, the official Google software repositories are added to your system. The file contents can be verified using the cat command:

The output is as follows:

3. Synergy realizes keyboard and mouse sharing between Windows and Ubuntu

Installation preparation

sudo apt-get install software-properties-common

Add qt4 source and set libcurl3,4 to coexist

sudo add-apt-repository ppa:rock-core/qt4
sudo add-apt-repository ppa:xapienz/curl34
sudo apt-get update

Install dependencies

sudo apt install  libqt4-dbus libqtcore4 libqtgui4 libqt4-network libqt4-opengl
sudo apt install libcurl4=7.68.0-1ubuntu2.5ppa1 
sudo apt install curl34

Install Synergy

sudo dpkg -i Synergy_1.9.0~rc3_amd64_ubuntu.deb

If there are dependency problems, you can try using

sudo apt --fix-broken install

Start the software

synergy

The synergy version 1.8.8 does not support Ubuntu 20.04 very well. According to my personal test, the following error message will pop up after each computer restart. However, restarting synergy manually can be used and there is no need to do it anymore.

System tray is unavailable

Simple use of synergy:

1. As a server (for sharing), configure the client's name (the name of the screen in the client) and location in Configure Server (note that the client name is preferably in English)
2. Check the Client button option on the host that is the client, and fill in the IP address of the server.
3. Solution to the error message "cannot bind address: Address already in use" appears:
   • Cancel SSL encryption in the edit option. Generally, you can connect in this way.
   • ps -aux | grep synergy, get the process pid before restarting

Share mouse, keyboard and files between two computers

4. Ubuntu terminal multi-window split-screen Terminator

Terminator can start multiple terminals in the same window in Ubuntu, but this method only applies to the graphical interface.

1. Installation and uninstallation commands

#安装
sudo apt-get install terminator
#卸载
sudo apt-get remove terminator

2. shortcut key

Ctrl+Shift+E    垂直分割窗口
Ctrl+Shift+O    水平分割窗口     F11         全屏
Ctrl+Shift+C    复制
Ctrl+Shift+V    粘贴
Ctrl+Shift+N    或者 Ctrl+Tab 在分割的各窗口之间切换
Ctrl+Shift+X    将分割的某一个窗口放大至全屏使用
Ctrl+Shift+Z    从放大至全屏的某一窗口回到多窗格界面

3. Modify the configuration file of the interface

sudo vim ~/.config/terminator/config

before fixing:

[global_config]
  handle_size = 1
[keybindings]
[layouts]
  [[default]]
    [[[child1]]]
      parent = window0
      type = Terminal
    [[[window0]]]
      parent = ""
      type = Window
[plugins]
[profiles]
  [[default]]
    background_image = None

After modification:

[global_config]
  geometry_hinting = False
  handle_size = 1
  inactive_color_offset = 1.0
  title_font = mry_KacstQurn Bold 11
  title_hide_sizetext = True
[keybindings]
[layouts]
  [[default]]
    [[[child1]]]
      parent = window0
      profile = default
      type = Terminal
    [[[window0]]]
      parent = ""
      type = Window
[plugins]
[profiles]
  [[default]]
    background_darkness = 0.76
    background_image = None
    background_type = transparent
    cursor_color = "#3036ec"
    custom_command = tmux
    font = Ubuntu Mono 13
    foreground_color = "#ffffff"
    login_shell = True
    show_titlebar = False
    use_system_font = False

4. Change the Ubuntu default terminal tool.
   The default terminal tool used in the Ubuntu system is gnome-terminal. After we install Terminator, we can use the dconf-tools tool to reset it.

Install dconf-toolssudo

apt-get install dconf-tools

After the installation is successful, enter the command "dconf-editor" in the terminal to open this tool, and then follow the steps below from the left menu bar to enter the specified menu item: org > gnome > desktop > applications > terminal Use gnome-
terminal The configuration is:

exec  gnome-terminal
exec-arg -x

Modify the configuration of using Terminator as the default terminal tool as:

exec  x-terminal-emulatore
xec-arg -e

5. View db data in Ubuntu

Install database software

sudo apt-get install sqlitebrowser
