Top X+1 things to do after installing Zorin OS 16

  1. Install CPU Power Manager.
    A way to reduce energy consumption. It is about limiting the frequency of the CPU, lowering its performance. While this is something that has always been doable, it generally requires complicated terminal commands. Fortunately, there is an extension for GNOME that can help you more easily configure and manage CPU frequency. CPU Power Manager uses the frequency scaling controller intel_pstate (compatible with almost all Intel CPUs) to control and manage CPU frequency from your GNOME desktop.

General characteristics of CPU Power Manager

  • We will be able to see the current CPU frequency. Obviously, we can use this window to see how often the CPU is running.
  • Set the maximum and minimum frequency. We will be able to establish maximum and minimum frequency limits in terms of percentage. Once these limits are set, the CPU will operate only in these ranges.
  • Activate and deactivate Turbo Boost. Most Intel CPUs have the 'Turbo Boost' feature. Through this, the CPU cores are increased beyond the normal maximum frequency seeking additional performance. While this can make the system more efficient, it also greatly increases energy consumption. Therefore, if we need to do anything intensively, it is good to be able to deactivate Turbo Boost and save energy.
  • We will be able create profiles with a maximum and minimum frequency. These can be easily activated or deactivated, instead of touching the values.

Moved posts of issues to general help to keep the tutorials and guides clean:

  1. Install nohang - package provides a highly configurable daemon for Linux which is able to correctly prevent out of memory (OOM) and keep system responsiveness in low memory conditions.

What is the problem?

OOM conditions may cause freezes, livelocks, drop caches and processes to be killed (via sending SIGKILL) instead of trying to terminate them correctly (via sending SIGTERM or takes other corrective action). Some applications may crash if it's impossible to allocate memory.

Here are the statements of some users:

"How do I prevent Linux from freezing when out of memory? Today I (accidentally) ran some program on my Linux box that quickly used a lot of memory. My system froze, became unresponsive and thus I was unable to kill the offender. How can I prevent this in the future? Can't it at least keep a responsive core or something running?"


"With or without swap it still freezes before the OOM killer gets run automatically. This is really a kernel bug that should be fixed (i.e. run OOM killer earlier, before dropping all disk cache). Unfortunately kernel developers and a lot of other folk fail to see the problem. Common suggestions such as disable/enable swap, buy more RAM, run less processes, set limits etc. do not address the underlying problem that the kernel's low memory handling sucks camel's balls."


"The traditional Linux OOM killer works fine in some cases, but in others it kicks in too late, resulting in the system entering a livelock for an indeterminate period."

To install on Zorin 16 /Ubuntu 20.04/20.10

To install from PPA:

$ sudo add-apt-repository ppa:oibaf/test

  1. Install and use Fish Shell - fish is a smart and user-friendly command line
    shell for Linux, macOS, and the rest of the family.

What’s Special About fish?

Easy to understand and use

Unlike the other shells that need a lot of setting-up to work the way you want them to, fish works perfectly right out of the box.

It ships with the most widely used features already included, which are present when you start using it without needing to install any additional plugins or tweak any configuration files unless you want to. Its syntax is simple, clean, and consistent.

Syntax highlighting

Syntax highlighting is a feature that we all wish our CLI could perform. It saves a lot of time and frustration. Well, fish does it, and it does it pretty well.

It shows you whether your command or the directory to be searched exists before you even hit enter. You’ll know whether you’re typing anything wrong before you hit enter. This makes it easier for people to parse commands, and find errors.

It highlights (most) errors in red, such as misspelled commands, misspelled options, reading from non-existing files, mismatched parenthesis and quotes, and many other common errors.

It also features highlighting of matching quotes and parenthesis. Oh, and it’s pretty, colorful.

Configuration for fish shells

The fish community maintains Oh My Fish, which is a shell framework inspired by Oh My Zsh. It offers a lot of beautiful prompt themes and awesome plugins, is lightweight, awesome, and easy to use.

It also offers a web-based configuration feature. Just type:


You will land on the website with which you can customize the skin of your shell.

Inline searchable history

This is an interactive feature of this Shell. You begin typing a command and press the up key to see all the times in the Shell history where you used that command before.

To search the history, simply type in the search query, and press the up key. By using the up and down arrow, you can search for older and newer matches. The fish history automatically removes duplicate matches and the matching substring is highlighted.

These features make searching and reusing previous commands much faster.

Inline auto-suggestion

Fish suggests commands as you type and shows the suggestion on the right of the cursor, in grey. If you mistype a command, it will show in red to indicate that it’s an invalid command.

It also suggests the most frequently used commands and auto-completes while you type, based on your history and valid files available.

Tab completion using man page data

Fish can parse CLI tool man pages in various formats. Type in a command and “tab” through all the suggested auto-completions.

Steps to install and use Fish Shell

sudo apt install fish

Once the installation is completed, you can start using it by switching your current shell to Fish, for that type-


Set Fish as Default shell

After using some time, if you like this colorful and friendly shell, then you can set it system default instead of bash.

chsh -s /usr/bin/fish

Log out of your system and log in again to apply the changes.


To change Fish properties, we can create a configuration file-

nano ~/.config/fish/

Switch back to Bash

If you didn’t like Fish and want back your Bash again on the terminal, then run

chsh -s /usr/bin/bash

log out and log in again.

To learn more about this shell command see the official documentation.

  1. Install and Use Gdu Disk Usage Analyzer - Linux has plenty of tools and commands for checking disk utilization. Some of these tools and commands come pre-installed. Take a look at the following list of commands for checking disk usage information, these can be found on many Linux distros by default:

df: shows usage for file system disk space.
du: estimates disk usage for files, directories.
ls -al: displays all the contents of a folder.
stat: shows the status of a file and file system.

Ubuntu also has a GUI-based tool called ‘Disk Usage Analyzer’ for analyzing disk usage. Likewise there is another tool ‘GDU Disk Usage Analyzer’ to view disk usage on many Linux-based distros and macOS.

GDU is written in ‘Go’ language and the official GitHub page frames it as ‘Pretty fast disk usage analyzer’ particularly for SSDs. It also works for HDDs but the performance is not as efficient as in SDD.

  1. Install timeshift-autosnap-apt - Timeshift auto-snapshot script which runs before any apt update|install|remove command using a DPkg::Pre-Invoke hook in APT. Works best in BTRFS mode, but RSYNC is also supported (on ext4 might be slow though, but your system is automatically snapshot before upgrade/install)


  • This script is a fork of timeshift-autosnap from the AUR, but adapted for usage with the APT package manager of Debian or Ubuntu based systems.
  • Creates Timeshift snapshots with a unique (customizable) comment.
  • Keeps only a certain number of snapshots created using this script.
  • Deletes old snapshots which are created using this script.
  • Makes a copy with RSYNC of /boot and /boot/efi to /boot.backup before the call to Timeshift for more flexible restore options.
  • Can be manually executed by running sudo timeshift-autosnap-apt.
  • Autosnaphots can be temporarily skipped by setting "SKIP_AUTOSNAP" environment variable (e.g. sudo SKIP_AUTOSNAP= apt upgrade)
  • Supports grub-btrfs which automatically creates boot menu entries of all your btrfs snapshots into grub.
  • For a tutorial how to use this script in production to easily rollback your system, see System Recovery with Timeshift.

Full Article and Installation: GitHub - wmutschl/timeshift-autosnap-apt: Timeshift auto-snapshot script for Ubuntu and Debian based systems which creates snapshots of your system with timeshift before a package install, remove or upgrade using DPkg::Pre-Invoke hook in apt. Fork of timeshift-autosnap from AUR.

That is a good suggestion and they are very similar.
That thread is covering a particular video guide and it's suggestions, whereas this one is aimed toward user suggestions. Merging them may also get confusing as the timestamps of the postings would really spread them out through the thread.
There is a splinter thread to this one, also... on Discussing the topics of this thread, since it was getting pretty filled by non-suggestions.

You can try out apt-fast. apt-fast is a shell script wrapper for “apt-get” that improves updated and package download speed by downloading packages from multiple connections simultaneously. If you frequently use terminal and apt-get to install and update the packages, you may want to give apt-fast a try. Install apt-fast via official PPA using the following commands:

sudo add-apt-repository ppa:apt-fast/stable
sudo apt-get update
sudo apt-get install apt-fast

Then head over to here for help with configuring it.
