Files app (aka Nautilus) has been ported to GTK4 plus LibAdwaita, so it has adaptive UI that show/hide left sidebar automatically according to app window size. In addition, the “undo” pop up has been moved to bottom in file manager, which no longer interrupt your workflow. Context (right-click) menu, file properties, and about dialog have been redesigned with touch-friendly UI.

  • Click app icon on dock to switch windows if multiple instances opened.
  • New icon in top-right system menu to launch screenshot UI

Compare to Ubuntu 22.04 LTS, Ubuntu 22.10 runs apparently faster and smoother, especially when switching light and dark theme and accent colors. It however has only 9 months of life as a short term release.

Download Ubuntu 22.10:

Ubuntu 22.10 desktop and server .iso images are available to download at the link below:

How to Install OpenShot 3.1.0 via PPA in Ubuntu 22.04 | 20.04 | 18.04

Last updated: April 8, 2023 — 2 Comments

For those looking for the native .deb package of OpenShot 3.1.0, here’s how to install it from PPA in Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, and Ubuntu 23.04.

The official openshot PPA is back with the latest packages for all current Ubuntu releases and their derivatives, such as Linux Mint. User can now easily install the latest video editor package by following the steps below one by one.

Just found that the official openshot PPA seems not being updated for quite a period of time, when I was trying to get the latest package of this video editor today. Though, the software is still being developed.

So I tried building myself and uploaded into this unofficial PPA for those who prefer native .deb package to AppImage or Flatpak.

NOTE this unofficial PPA contains the packages for Ubuntu 22.04, Ubuntu 20.04, and Ubuntu 18.04, though has only minor tests in Ubuntu 22.04.

1. Add the PPA

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the command below into terminal and hit Enter to add PPA:

sudo add-apt-repository ppa:openshot.developers/ppa

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

2. Refresh package cache

Ubuntu 20.04 and higher will automatically refresh system package cache while adding PPA. Though old Ubuntu 18.04 and Linux Mint do not.

To manually update the cache, run command:

sudo apt update

3. Install/Update OpenShot

Finally, either install the video editor by running command in terminal:

sudo apt install openshot-qt python3-openshot

Or use ‘Software Updater’ to update it from an old version.

Uninstall:

To remove the Ubuntu PPA, either open “Software & Updates” and delete the source from ‘Other Software’ tab:

or run the command below in terminal:

sudo add-apt-repository ppa:openshot.developers/ppa

And remove the editor for choice by running command:

sudo apt remove --autoremove openshot-qt python3-openshot

Audacity 3.2.0 Released with Realtime Effects & Apple Silicon Support

Last updated: September 25, 2022 — Leave a comment

Audacity audio editor got a new major update few days ago, features real-time effects and VST3 support.

In the new 3.2.0 release, there’s a new “Effects” button in the tracks menu, allowing to place realtime effects. However, it does not yet ship with any effect so far. User has to get effects via plugins, though only Audio Units (macOS only), VST3, LV2, and LADSPA formats are supported at the moment.

The release also merged the mixer bar with the meter bars. The device tool-bar has been replaced with a new Audio Setup button, though it can be re-enabled via “View -> Toolbars” menu.

As the screenshot above shows you, there also introduced a new “Share Audio” button, allowing to upload audio into audio.com either with login account or anonymously, then share the link with your friend.

Other changes in Audacity 3.2.0 include:

  • Apple Silicon (arm64) is now supported on macOS. Though, need arm64 versions of FFMPEG and plugins.
  • Add support for Wavpack
  • Possible to compile without JACK present in Linux.
  • Use XDG directories on Linux. Need to delete .audacity-data and .audacity folders in user home if exist.
  • Use mpg123 as mp3 importer instead of mad.
  • Update license to GNU General Public License V3, though most code files remain GPLv2 or later.
  • Update icons, remove Zoom tool and various bug-fixes.

How to Install Audacity 3.2.0 in Ubuntu Linux

There seems no native .deb package for the latest Audacity. User can however get the application via the universal AppImage, Snap, or Flatpak that works in most Linux.

Option 1: AppImage

For the non-install AppImage, go to the github releases page and grab the package under “Assets” section:

Audacity Releases (Assets)

Then, right-click on the package and open “Properties” dialog. Add executable permission under ‘Permissions’ tab and finally click run the package to launch Audacity.

Audacity AppImage

Option 2: Flatpak

User can also install Audacity via universal Flatpak package that runs in sandbox.

First, press Ctrl+Alt+T on keyboard to open terminal in Ubuntu, then run command to make sure the daemon package is installed:

sudo apt install flatpak

Then install the audio editor as Flatpak by running command:

flatpak install https://dl.flathub.org/repo/appstream/org.audacityteam.Audacity.flatpakref

Like normal applications, search for and launch it from system start menu (‘Activities’ overview) after installation.

Option 3: Snap

Audacity is also available as Snap package that runs in sandbox. I put this method as last choice because it does not yet update to v3.2.0 at the moment of writing.

However, it’s quite easy to install for Ubuntu users. Simply open the Software App, search for and click install it:

Uninstall Audacity

Depends how you install the software package, uninstall the editor via:

  • For AppImage, just remove the package file.
  • For the Flatpak package, open terminal and run command: 
    flatpak uninstall org.audacityteam.Audacity
  • And remove the snap package by either using Ubuntu Software or running command in terminal: 
    sudo snap remove audacity

Stupid Simple App to create Light & Dark Wallpapers in GNOME

Last updated: September 23, 2022 — Leave a comment

Got photo images in both light and dark style? There’s a super simple application to set them as dynamic wallpapers in GNOME 42+ desktop.

As you may know, GNOME 42+ support light and dark wallpapers that change automatically depends on system color scheme. Ubuntu 22.04 does not support the feature, but in upcoming Ubuntu 22.10 you may add your own ones into wallpaper selection dialog:

It’s easy to group your light and dark photo images as a single wallpaper selection. Just create a XML file under “.local/share/gnome-background-properties” (create folder if not exist), and write following rules:

<?xml version="1.0"?>
<!DOCTYPE wallpapers SYSTEM "gnome-wp-list.dtd">
<wallpapers>
  <wallpaper deleted="false">
    <name>TYPE_NAME_HERE</name>
    <filename>/PATH/TO/PICTURE_LIGHT</filename>
    <filename-dark>/PATH/TO/PICTURE_DARK</filename-dark>
    <options>zoom</options>
    <shade_type>solid</shade_type>
    <pcolor>#3465a4</pcolor>
    <scolor>#000000</scolor>
  </wallpaper>
</wallpapers>

It will then be available in the “Appearance” settings pages (Ubuntu 22.10 will merge ‘Background’ into ‘Appearance’).

To make life easier, a stupid simple application called “Dynamic Wallpaper” is created to do the job. With it, you may just type a name, select the 2 photo images and click “Create” button.

As mentioned above, it automatically creates a XML file with the name you typed, and saves to “.local/share/gnome-background-properties” directory. It also makes a copy of the photo images into “.local/share/backgrounds“, and refers to them in the XML file.

When done, you may go to “Appearance” in GNOME Control Center (aka “Settings” utility) to select that wallpapers.

How to Install the “Dynamic Wallpaper” app

The tool is available to install as Flatpak package, that works in Ubuntu 22.10+, Fedora 36+, Arch and Manjaro Linux with GNOME Desktop.

1. First, search for and open terminal from ‘Activities’ overview (or press Ctrl+Alt+T on Ubuntu). When it opens, run command to install Flatpak daemon:

sudo apt install flatpak

2. Next, run the command below to install the tool:

flatpak install https://dl.flathub.org/repo/appstream/me.dusansimic.DynamicWallpaper.flatpakref

If you’re first time installing a Flatpak package, there will be also hundred MB run-time libraries to install.

Finally, click the top-left corner ‘Activities’, then search for and open the application:

Uninstall:

To remove the tool, open terminal and run command:

flatpak uninstall --delete-data me.dusansimic.DynamicWallpaper

And clear useless libraries via flatpak uninstall --unused.

Other changes include:

  • New system properties for System.out and System.err.
  • upgrade Unicode support to 14.0
  • HTTPS channel binding support for Java GSS/Kerberos.
  • Support for PAC-RET protection on Linux/AArch64
