Workspaces are now arranged horizontally, and the overview and app grid are accessed vertically. And it supports three-finger touchpad gestures to toggle overview and switch workspaces.

The “standard” app layout, dark header-bar along with light window color, has been removed. Now Ubuntu 21.10 includes only “light” and “dark” mode to choose from the ‘Appearance’ settings page.

What’s New in gThumb 3.12.0:

The new release includes many new features compare to the previous stable 3.10.x. They are all introduced in the 3.11 development releases, so you may already enjoy using them for a period of time.

With libheif library, gThumb now opens AVIF, HEIF (include Apple’s HEIC) images, and allows to save images as AVIF. And it supports JPEG XL images using the jpeg-xl library. A template editor is available to edit text values with special codes, for use in script commands, rename templates, print header and footer, etc.

Besides that, it improved file navigation for directory contains thousands of images. The file list now starts more thumbnailers in parallel, status bar has button to show the progress dialog. And the color picker tool shows colors in two more formats: rgb in % and hsl. Others include:

  • Allow to set shortcuts to activate filters.
  • Allow to mount unmounted volumes.
  • Add file actions to the viewer context menu.
  • Read color profiles from png files as well.
  • Option to show/hide the status bar.

For those already running gThumb 3.11.4, there are only bug-fixes and translation updates.

How to Install gThumb 3.12.0 in Ubuntu:

The software does not provide official binary package. Besides building from the source tarball, you may install it via the unofficial Ubuntu PPA.

1. Add the Ubuntu PPA.

The PPA so far provides packages for Ubuntu 20.04, Ubuntu 21.04, Ubuntu 21.10, and Linux Mint 20. It contains package for Ubuntu 18.04 but lacks JPEG XL support.

Firstly open terminal either from start menu or by pressing Ctrl+Alt+T on keyboard. When it opens, paste the command below into terminal and hit run:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

2. Update system package cache.

Adding PPA will automatically refresh the package cache in Ubuntu 20.04 and higher. However old versions and some Ubuntu based systems does not. To do it manually, simply run command in terminal:

sudo apt update

3. Install / Upgrade gThumb.

Finally, either run the apt install command in a terminal window to install the image viewer:

sudo apt install gthumb

Or use the Software Updater (Update Manager) utility to receive package updates. Un-check other packages from the PPA if you don’t want them.

Uninstall / Restore gThumb:

You can restore to the stock version of the image viewer and organizer by purging the PPA repository. To do so, simply run command:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/apps

You may also keep the gThumb package but remove the Ubuntu PPA, since it contains many other software packages that you don’t prefer. To do so, either run command in terminal:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/apps

Or remove the repository line under ‘Other Software’ tab via Software & Updates utility.

August 31st 2021 at 16:34
By: Ji m

Giara, the Reddit app for Gnome, released version 1.0. It’s now based on GTK4.

Giara is a free and open-source client for Reddit that runs on Linux. The software is written in Python 3 programming language. With GTK framework and libadwaita (formerly libhandy), it has a modern and adaptive user interface works on both desktop and Linux mobile devices.

What’s New in Giara 1.0:

The new release moves to GTK4 and libadwaita (the GTK 4 port of libhandy), makes the UI more modern. However, due to outdated system libraries the PPA package (unofficial) will not update until Ubuntu 22.04 (maybe).

With built-in image viewer, the 1.0 release has new and improved picture view, adds support for picture galleries. The NSFW (not safe for work) images that involve nudity, sexual content, and so forth are now blurred.

Other changes include optimized post lists based on ListView, custom emojis in post flairs, many improvements and bug-fixes.

How to Install Giara:

For Arch Linux only, an AUR repository is available, while other Linux can install the app via Flatpak package.

Flatpak is an universal Linux package format runs in sandbox. It’s supported out-of-the-box in some distributins, e.g., CentOS, Fedora, Linux Mint, though it needs a separate daemon for running the apps.

And below will show you how to install Giara Flatpak in Ubuntu 20.04 and higher:

1.) Firstly, open terminal (Ctrl+Alt+T) and run command to install the daemon if you don’t have it:

sudo apt install flatpak

Flatpak supports Ubuntu 18.04 and even Ubuntu 16.04, though you have to add the Ubuntu PPA first!

2.) Then add the flathub repository, the preferred place to get Flatpak apps.

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

3.) Finally, install the Reddit App via command:

flatpak install flathub org.gabmus.giara

Like normal apps, open it by searching from start menu and enjoy!

Uninstall Giara:

To remove the app, simply use command:

flatpak uninstall --delete-data org.gabmus.giara

Remove the --delete-data if you want to keep the personal data for the app. And run command to run unused runtime which may free up more disk spaces.

flatpak uninstall --unused

Linux Kernel 5.14 was released with latest features and new hardware support. Here’s how to install it in Ubuntu.

Linus Torvalds announced the release of Kernel 5.14 this Sunday:

So I realize you must all still be busy with all the galas and fancy balls and all the other 30th anniversary events, but at some point you must be getting tired of the constant glitz, the fireworks, and the champagne. That ball gown or tailcoat isn’t the most comfortable thing, either. The celebrations will go on for a few more weeks yet, but you all may just need a breather from them.

And when that happens, I have just the thing for you – a new kernel release to test and enjoy. Because 5.14 is out there, just waiting for you to kick the tires and remind yourself what all the festivities are about.

What’s New in Kernel 5.14:

How to Install Kernel 5.13 in Ubuntu:

The Mainline Kernel PPA provides packages for Ubuntu 21.04 and Ubuntu 21.10. However, it does not include any Ubuntu-provided drivers or patches, and NOT supported and are not appropriate for production use.

The .deb packages for amd64, arm64, ppc64el and s390x are available to download at the link below:

For personal computers, select generic for common system, or lowlatency for a low latency system (e.g. for recording audio):

  • linux-headers-5.14.0-xxxxxx_all.deb
  • linux-headers-5.14.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  • linux-modules-5.14.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  • linux-image-xxx-5.14.0-xxx-generic(/lowlatency)_xxx_amd64.deb

A graphical tool, Ubuntu Mainline Kernel Installer, is available to make life easier.

For those familiar with Linux command, open terminal and run commands one by one to download & install the packages:

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14/amd64/linux-headers-5.14.0-051400_5.14.0-051400.202108292331_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14/amd64/linux-headers-5.14.0-051400-generic_5.14.0-051400.202108292331_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14/amd64/linux-image-unsigned-5.14.0-051400-generic_5.14.0-051400.202108292331_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14/amd64/linux-modules-5.14.0-051400-generic_5.14.0-051400.202108292331_amd64.deb

sudo dpkg -i *.deb

Once installed, restart your computer and enjoy!

Since the previous packages needs Ubuntu 21.04+, you may keep an eye on this third-party PPA which re-build the Kernel with Ubuntu 20.04 LTS support.

Uninstall Linux Kernel 5.14:

Restart your machine and select boot with the previous kernel in boot menu ‘Grub2 -> Advanced Option for Ubuntu’. Then run command to remove Linux Kernel 5.14:

Happy 30th Birthday to Linux!

Today, August 25, is the 30th anniversary of Linux!

It was 30 years ago that Linus Torvalds announced the operating system, just a hobby!

Hello everybody out there using minix-

I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I’d like any feedback on things people like/dislike in minix; as my OS resembles it somewhat (same physical layout of the file-sytem due to practical reasons)among other things.

I’ve currently ported bash (1.08) an gcc (1.40), and things seem to work. This implies that i’ll get something practical within a few months, and I’d like to know what features most people want. Any suggestions are welcome, but I won’t promise I’ll implement them :-)

Linux is a family of open-source operating systems based on the Linux kernel. The Kernel now has more than 31 million lines of code. And there are almost one thousand Linux distributions exist.

100% of the world’s top 500 supercomputers run on Linux. It’s trusted by NASA and JPL to run a helicopter on Mars.

And Linux is getting better and better on desktop with the power of GNOME, KDE, X11, Wayland, Ubuntu, Fedora, and the open-source communities!

gThumb Image Viewer & Organizer 3.11.4 Adds AVIF/HEIF Support [PPA]

August 23rd 2021 at 17:58
By: Ji m

The GNOME image viewer and organizer app, gThumb 3.11.4 was released! PPA updated with Ubuntu 18.04, Ubuntu 20.04, Ubuntu 21.04, and upcoming Ubuntu 21.10 support.

Thanks to libheif library, the new release introduced HEIF file format support, so it can now handle photos imported from your iOS devices. Also AVIF, an image file format specification for storing images or image sequences compressed with AV1 in the HEIF file format is supported, and you can save file as AVIF.

There’s a performance improvement for browsing directory with thousands of images, so users will get a smoother experience. The file list now starts more thumbnailers in parallel, status bar has a button to show the progress dialog. And the color picker tool shows colors in two more formats: rgb in % and hsl.

Other changes include:

  • Allow to set shortcuts to activate filters.
  • Added a template editor to edit text values with special codes: script commands, rename templates, print header and footer, etc.
  • Allow to mount unmounted volumes.
  • Allow to keep browsing while executing long-running external tools.
  • Show the properties in a single column to save horizontal space.
  • Bug-fixes and translation updates.

How to Install gThumb 3.11.4 in Ubuntu:

The software lacks a repository for Ubuntu packages. Besides building from the source tarball, I’ve made the packages into the unofficial PPA for Ubuntu 18.04, Ubuntu 20.04, Ubuntu 21.04, Ubuntu 21.10, Linux Mint 20 and derivatives.

Since the Ubuntu 18.04 build needs updated FFmpeg libraries that may break existing installations, the packages has been removed. Try purge the PPA if you want to restore the ffmpeg:
sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/apps
1.) Add the PPA

To add the PPA, open terminal either from the ‘show applications’ menu or by pressing Ctrl+Alt+T on keyboard. When terminal opens, run command:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

2.) Install / Upgrade gThumb

You can then either upgrade the image viewer from an old version via Update Manager (Software Updater), or run command in terminal:

sudo apt install gthumb

NOTE for Linux Mint, you have to run sudo apt update to refresh package cache first.

Uninstall gThumb & the Ubuntu PPA

To remove gThumb image viewer, run command:

sudo apt remove --autoremove gthumb gthumb-data

To remove the Ubuntu PPA, either run the apt-add-repository command with --remove flag, or use Software & Updates -> Other Software.
