Things To Do After Installing Ubuntu 20.04
Every time I install a new software, the first thing to do is to configure it. Doing the configuration could be very annoying, especially when you are doing a re-installation, you have to do something you did before but you couldn’t remember well. Some software has a good default setting, I mean the setting suits me, I don’t need to do any extra setting, but for some software, the default setting doesn’t fit my habits, I have to do a lot of settings, I even have to export and backup the config file (if possible) in case of re-installation. Ubuntu is the latter, the annoying one.
In fact, the main factor that prompted me to rebuild my blog was that I was going to reinstall my operating system for my computer to give it a refresh. I am not going to install Ubuntu again, because Gnome isn’t my type at all. I would say it disobeys rule of the infinite edges of Fitts’s law at user interface. The top bar should be to blame. Due to the existence of the top bar, the close button isn’t at the right-top corner of the screen, and the browser tabs aren’t at the top edge, these are very inconvenient for my operation, I could have closed the windows without focusing on the position of the mouse cursor, even with my eyes closed, but the top bar ruined everything, it’s so painful. And this post is only for record, I will try using Kubuntu instead of Ubuntu later, maybe I will not use Ubuntu anymore. Another reason for me to drop Ubuntu is that the desktop environment is not responding from time to time since being installed, especially the Firefox browser.
This the Step 0. Download via torrent is recommended, Chinese residents are also recommended to download from mirror site in China, such as USTC Open Source Software Mirror.
Using a software repositories mirror near your location will give you better download speed. As for Chinese residents like me, I would recommend apt mirrors provided by USTC, tuna and Aliyun. They can be selected at Software & Updates.
For ppa, USTC Mirror provides reverse proxy. Edit ppa source lists in
/etc/apt/sources.list.d/, change the
http://ppa.launchpad.net/ part to
For Flatpak’s Flathub, use the mirror provided by SJTUG. Snap doesn’t have a mirror like this, that is why I prefer Flatpak over Snap.
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
For pypi, use the mirror provided by tuna.
python -m pip install --upgrade pip
For npm, use the mirror provided by Aliyun npmmirror, formerly known as Taobao npm Mirror.
npm install -g cnpm --registry=https://registry.npmmirror.com
Rime is my only choice but the configuration is also very complicated so that I have to backup the config files.
Config file location:
- Shared folder:
- User folder:
By the default Grub setting, there is a splash screen while the system is starting, showing only the Ubuntu logo and a loading progress bar. I prefer seeing detailed information.
Install grub-customizer, the GUI tool to edit menu entries.
sudo apt install grub-customizer
The time zone will be incorrect when you install both Windows and Ubuntu on your computer.
timedatectl set-local-rtc 1 --adjust-system-clock
Most operating system will turn off the screen and sleep when inactive. As for the duration, the default setting may be too long or too short for different users, so this should be customized.
- Settings > Power > Automatic Suspend > [1 hour]
(the computer will sleep after inactive for 1 hour)
- Settings > Privacy > Screen Lock > Automatic Screen Lock [OFF], Lock Screen on Suspend [OFF]
(I don’t want to enter my password every time I wake up the computer so I disable auto lock)
- dconf-editor > org.gnome.desktop.session > idle-delay 
(Settings>Power>BlankScreen only have limited options, you can’t set a specific duration)
By default, when you click the button of a running application at the dash panel (not really sure about the name, dash or dock? Anyway the left side panel), it won’t minimize like that in Windows.
- dconf-editor > org.gnome.shell.extensions.dash-to-dock > click-action [minimize-or-previews]
Ubuntu 18.04 doesn’t even provide this minimize-or-previews option, it will be very troublesome when you want to switch among different windows of the same application in Ubuntu 18.04.
I am a person who pays attention to fonts, not only at screen display but also at books typesetting. The fonts config at Linux is much easier than that at Windows, as long as you know how to do that. The official documentation of font-config is too complicated. The only thing I want to know is that how to set a fallback list for fonts, that is my only requirement. Luckily, I found some easy-to-follow tutorials.
Here is my config file.
I will also deleted fonts I don’t need, maybe this is because of Obsessive-Compulsive Disorder. List all the preinstalled fonts.
sudo apt show list --installed | grep fonts-
Then uninstall the unneeded ones. The apt purge command doesn’t delete them completely because there are still a
.uuid file left so the nonempty directories aren’t deleted. I have to delete them manually. By the way, Font Manager is a useful software to view your fonts.

By default, when you press the
PrintScreen key, a screenshot of the whole screen will be generated and saved to the
~/Pictures/ directory. However, I may press the
PrintScreen key by mistake when I am going to press the
←BackSpace key. So I change it to
Ctrl+PrintScreen to avoid this.
- Settings > Keyboard Shortcuts > Save a screenshot to Pictures [Ctrl+Print]
- Settings > Keyboard Shortcuts > Save a screenshot of an area to Pictures [Ctrl+Alt+A]
I will also recommend a powerful screenshot tool called Flameshot.
I prefer the ESR (Extended Support Release) version because I don’t like updates. If possible, I would like to stay at the 78.15.0esr version because I don’t like the new interface.
sudo add-apt-repository ppa:mozillateam/ppa
base64 --decode gfwlist.txt > gfwlist-decode.txt
This is the most troublesome, Ubuntu is not out-of-the-box for me. I need to install a lot of Gnome extensions. First of all, Tweaks and chrome-gnome-shell should be installed.
sudo apt install gnome-tweaks chrome-gnome-shell
- Start Overlay in Application View, press the Super(Windows) key to show applications(Start menu).
- ESCape Overview, close the Overview with a single ESC press.
- Applications Overview Tooltip, it should have been supported natively, shouldn’t it?
- Panel Date Format
- User Themes
- ibus font setting
- Dynamic Panel Transparency
- Unite, move the close button to top-lest corner, not a best solution for me but so far the best solution, alternatively Dash to Panel, or just switch to KDE from Gnome.
- Internet Speed Monitor, not the one with the most config options but the default style is enough for me.
Not sure about the exact name, I mean the view when you click the Show Applications button at the left-bottom corner, just like a Start menu at Windows 8.1. I am not allow to delete the applications icons directly from the view, the way to do that is to go to
# some more ls aliases
- dtrx (Do The Right eXtraction), no need to remember different commands for different formats of archive files.
- mpv or SMPlayer, video player. If you want to try a geeky one, then Mplayer, but editing the config file won’t be a easy thing.
- ONLYOFFICE, WPS Office or LibreOffice
- Sublime Text, unfortunately another good text editor Notepad++ doesn’t support Linux while Notepadqq isn’t good enough.
- GIMP, image editor
- HexChat, IRC client
- Aegisub, subtitle editor
