PHP 8.2 Released, How to Install in Ubuntu 22.04 | 20.04 via PPA

Last updated: December 9, 2022 — Leave a comment

PHP finally released 8.2.0 release after 7 release candidates. Here are the new features and how to install guide for all current Ubuntu LTS.

PHP 8.2.0 allows to mark a class as readonly, which will add the readonly modifier to every declared property, and prevent the creation of dynamic properties. Moreover, using the AllowDynamicProperties attribute on readonly class will trigger a compile-time error.

Other release highlights in PHP 8.2.0 include:

  • Disjunctive Normal Form (DNF) Types
  • New stand-alone types: null, false, and true
  • New “Random” extension
  • Constants in traits
  • Deprecate dynamic properties

There are as well numerous bug-fixes and other changes in the release. See the changelog for details.

How to Install Php 8.2 in Ubuntu:

Not recommended for beginners. Only install PHP 8.2 for web developing purpose or there’s specific feature or bug-fix you need in this release.

The popular Ondřej Surý’s PPA has built the package for all current Ubuntu LTS: Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 22.04.

1. First, open terminal or connect to your Ubuntu server and run command to add the PPA:

LC_ALL=C.UTF-8 sudo add-apt-repository ppa:ondrej/php

Run sudo apt install software-properties-common in case the command does not exist. And, type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Then, install Php packages accordingly. For example, install apache2 module and mysql module via command:

sudo apt install php8.2 libapache2-mod-php8.2 php8.2-mysql

Or install the FPM-CGI binary for use with Nginx:

sudo apt install php8.2 php8.2-fpm php8.2-mysql

For Ubuntu 18.04, run sudo apt update first to refresh package cache.

After installed it, remember to configure your http server (apache 2 or nginx) for the new PHP package, and configure php8.2 via files under ‘/etc/php/8.2/’.

Uninstall Php 8.2

To remove the package, simply run command:

sudo apt remove --autoremove php8.2 libapache2-mod-php8.2 php8.2-*

And remove the Ubuntu PPA via command:

sudo add-apt-repository --remove ppa:ondrej/php

Automatically Change Power Mode in Ubuntu 24.04 | 22.04 base on Power Supply

Last updated: May 5, 2024 — 5 Comments

Want to change system power mode between Performance, Balanced, and Power Saver automatically when plug / un-plug power supply?

Here’s an extension can do the job for Ubuntu 22.04, Ubuntu 24.04, Fedora 38/39, Debian 12, Arch and other Linux with GNOME from version 42 to 46.

GNOME introduced setting options to switch power mode since v40. For laptop running on AC power supply, user may use ‘Performance’ mode for gaming or doing heavy work. To prevent from draining power fast after un-plug AC power, it’s better to switch to ‘Balanced’ mode, or even ‘Power Saver’ mode when battery level is low. To automate this work, ‘Power Profile Switcher’ extension was born.

How to Monitor GPU Usage in Ubuntu 24.04 | 22.04

Last updated: May 6, 2024 — Leave a comment

Unlike Windows, Ubuntu so far does not have real-time GPU usage info displayed in its system monitor application. If you want to check how much your graphic card is in use, then this simple tutorial may help!

Method 1: Use Mission Center (Graphical App)

A graphical app is always good choice for beginners. And, Mission Center is the one that provides a Windows Task Manager look like interface for monitoring system resource usage.

It supports monitoring overall GPU usage, video encoder and decoder usage, memory usage and power consumption. With the power of nvtop, it supports AMD, Apple, Huawei, Intel, NVIDIA and Qualcomm GPUs.

To install Mission Center, press Ctrl+Alt+T on keyboard to open up a terminal window. Then, run the commands below one by one to install the Flatpak package.

  • First, run command to enable Flatpak support: 
    sudo apt install flatpak

  • Then, install Mission Center flatpak package via command: 
    flatpak install https://dl.flathub.org/repo/appstream/io.missioncenter.MissionCenter.flatpakref

If this is the first app installed as Flatpak package, you may need to log out and back in to make app icon visible in start menu (or Gnome app grid).

(Optional) To uninstall Mission Center, open terminal and run command:

flatpak uninstall --delete-data io.missioncenter.MissionCenter

Also run flatpak uninstall --unused to clear useless runtime libraries.

Method 2: Monitor GPU usage from Command Line

For Ubuntu server and those who prefer to the job from command line, there are few tools can do the job. They include intel-gpu-tools for Intel GPU, and nvtop for Intel, AMD, and NVIDIA.

Check Intel GPU usage in Ubuntu:

For the integrated Intel graphics card, there’s a command line tool intel_gpu_top can do the job.

1. First, press Ctrl+Alt+T on terminal to open a terminal window. When it opens, run command to install the package:

sudo apt install intel-gpu-tools

Type user password when it asks (no asterisk feedback) and hit Enter.

2. Then, run command to start it:

sudo intel_gpu_top

As you can see, it shows real-time IMC read and write speed, power usage, as well as percentage usage of 3D/Render, Blitter, Video, and VideoEnhance.

Monitor AMD/NVIDIA GPU usage in Ubuntu

For NVIDIA and AMD graphics card, there’s a htop like task monitor called nvtop (Neat Videocard TOP).

It shows real-time GPU and GPU Memory usage in both total and per process basis, along with temperature, power usage, and graph information.

nvtop, image from https://github.com/Syllo/nvtop

nvtop also supports Intel GPU, however, it does not work in my case with i5-4590 (HD4600), and i3-6006U (HD 520).

Install nvtop in Ubuntu:

The tool is available in Ubuntu system repository, but old for Ubuntu 22.04 and Ubuntu 20.04. For the latest version, it has an official PPA contains the most recent package.

1. First, press Ctrl+Alt+T on keyboard to open terminal. Then, run command to add the PPA:

sudo add-apt-repository ppa:flexiondotorg/nvtop

For Ubuntu 24.04, skip the PPA, just the command below to install. Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Then, run command to install the tool:

sudo apt install nvtop

For Linux Mint, run sudo apt update first to refresh package cache.

Finally, either search for and launch it from ‘Activities’ overview (or start menu), or run nvtop command to start monitoring your GPU.

(Optional) Remove nvtop

To remove the PPA repository, open terminal and run command:

sudo add-apt-repository --remove ppa:flexiondotorg/nvtop

And remove nvtop if you want via command:

sudo apt remove nvtop

Fix TypeCatcher (Google Fonts Installer) does not launch in Ubuntu 22.04

Last updated: December 5, 2022 — 2 Comments

This simple tutorial shows how to fix the launching issue for TypeCatcher in Ubuntu 22.04 or other Linux with Python 3.9 & higher.

TypeCatcher is a simple GTK application to download and install Google webfonts for off-line use. The app is available to install in Ubuntu Software for all current Ubuntu releases. However, it does not launch in Ubuntu since 21.10.

TypeCatcher, download & install Google Fonts

When trying to launch it from command line, it outputs something like this:

Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/typecatcher_lib/Application.py”, line 30, in on_activate
self.window = TypeCatcherWindow.TypeCatcherWindow()
File “/usr/lib/python3/dist-packages/typecatcher_lib/Window.py”, line 47, in __new__
builder = get_builder(‘TypeCatcherWindow’)
File “/usr/lib/python3/dist-packages/typecatcher_lib/helpers.py”, line 44, in get_builder
builder.add_from_file(ui_filename)
File “/usr/lib/python3/dist-packages/typecatcher_lib/Builder.py”, line 86, in add_from_file
ele_widgets = tree.getiterator(“object”)
AttributeError: ‘ElementTree’ object has no attribute ‘getiterator’

The issue is because of the removal of getiterator() methods from xml.etree.ElementTree module in Python 3.9, which was deprecated since Python 3.2.

As the announcement indicates, simply use iter() method instead will fix the issue.

Methods getchildren() and getiterator() of classes ElementTree and Element in the ElementTree module have been removed. They were deprecated in Python 3.2. Use iter(x) or list(x) instead of x.getchildren() and x.iter() or list(x.iter()) instead of x.getiterator().

1. First, search for and open a terminal window from either start menu or ‘Activities’ overview depends on your desktop environment.

2. When terminal opens, run command to edit the file that contains the ‘getiterator()’ method (see the first screenshot). In the case, it’s “/usr/lib/python3/dist-packages/typecatcher_lib/Builder.py”.

sudo gedit /usr/lib/python3/dist-packages/typecatcher_lib/Builder.py

replace gedit to your favorite text editor, or use nano command line editor that works in most Linux.

3. When files opens, find out and replace tree.getiterator with tree.iter.

For Gedit text editor, just go to menu, click open ‘Find and Replace’ dialog. Finally, insert tree.getiterator as ‘Find’, and ‘tree.iter‘ as ‘Replace with’, then click on ‘Replace All’ button.

For nano text editor, press Alt+R when the file opens in terminal window. Then type tree.getiterator when it indicates ‘Search (to replace)’, hit Enter, and insert tree.iter when prompts ‘Replace with’. Finally, hit Enter and type y. Or, just use arrow keys to find and replace the keyword (there are 2) manually. And, press Ctrl+x, type y, and hit Enter to save changes.

After saving the file, try to launch it either from ‘Activities’ overview or command line, and enjoy!

Want to measure your application launch time in Linux? There’s an extension can do the job for GNOME desktop.


Meaning Ubuntu, Fedora workstation, and other Linux with GNOME desktop can easily tell how much time it takes for launching an application, which is useful for benchmark and/or software developing purpose.


With the extension enabled, every time you launching an application, an on-screen display pops up shows the loading time in millisecond. Not only for native .deb/.rpm, but also for Snap and Flatpak applications. 


How to Install the App Start Time Measure extension


For Ubuntu 22.04, first search for and install “Extension Manager” from Ubuntu Software.


Install Extension Manager in Ubuntu 22.04+


Then launch “Extension Manager” and use it to search & install ‘application start time measure’:




For Ubuntu 20.04, first press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the agent package:


sudo apt install chrome-gnome-shell




Then, go to extension page in the link below and use ON/OFF switch to install it:




Applications Startup Time Measure




Install the browser extension if prompted via link in that page and refresh if you don’t see the ON/OFF switch.




After installing the extension, it should be enable automatically (verify via ‘Gnome Extensions’ or ‘Extension Manager’). You can then launch something and see the magic!
