Darktable 4.2.1 Released with Various Bug-fixes, New Cameras Support

Last updated: March 3, 2023 — Leave a comment

Darktable, the free open-source photography application and raw developer, released version 4.2.1 a few days ago. Here’s how to install it in Ubuntu 20.04, Ubuntu 22.04 and Ubuntu 22.10.

Darktable 4.2.1 is a new point release. There’s no big features but minor changes. It now uses magic bytes to identify JPEG files, so even JPEG image with incorrect file extension is supported. Also, it adds ability to assign shortcuts to the “quick access” style and preset menus at the bottom of the darkroom view.

The release also added base support for Canon EOS Kiss X10/X10i, Leica M9 (dng), Nikon Z 30 (12bit-compressed, 14bit-compressed), OM System OM-1/OM-5, Panasonic DC-G95D/DC-G99D (4:3), Ricoh GR IIIx (dng).

It also adds White Balance Presets for Nikon Z 9, and noise profiles for Fujifilm GFX100S, Fujifilm X-H2/X-H2S, OM System OM-1, Sony ILCE-7SM3, Canon EOS 250D / Kiss X10 / Rebel SL3 / 200D Mark II, Canon EOS R7.

For more about Darktable 4.2.1, see the release note in github.

How to install Darktable 4.2.1 in Ubuntu via PPA

The software website refers to the OBS repository that contains native packages for Ubuntu, Debian, Fedora and SUSE.

Darktable OBS repository

For choice, here’s an unofficial Ubuntu PPA contains the packages for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10.

NOTE: There’s no JPEG-XL support, since the library is not available in Ubuntu repository until 23.04. And, the new release requires libheif >= 1.13.0, so HEIF support excluded in Ubuntu 22.04 and earlier. Please leave comment if you do need them.

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

sudo add-apt-repository ppa:ubuntuhandbook1/darktable

2. Linux Mint use may need to run command to manually refresh package cache:

sudo apt update

3. Finally install the photography software either via the command below:

sudo apt install darktable

Or by installing package updates via Software Updater. NOTE: You are strongly advised to take a backup first.

Darktable is also available as universal Flatpak package that works in most Linux systems.

Fix no window border issue

Darktable seems not rendering its window border in Ubuntu with default Wayland session. As a workaround, either switch back to classic Xorg session, or run Darktable using X11 backend.

To do so, either open terminal (Ctrl+Alt+T) and run command to launch Darktable from command line:

GDK_BACKEND=x11 darktable

Or, modify the shortcut icon file via following steps:

1. Open terminal (Ctrl+Alt+T) and copy the shortcut file to local folder by running command:

sudo cp /usr/share/applications/org.darktable.darktable.desktop ~/.local/share/applications

2. Change the owner ship to current user:

sudo chown $USER:$USER ~/.local/share/applications/org.darktable.darktable.desktop

3. Edit the file with gedit text editor:

gedit ~/.local/share/applications/org.darktable.darktable.desktop

For Ubuntu 22.10 +, replace gedit with gnome-text-editor.

4. Finally, find out the line started with Exec and change it into Exec=env GDK_BACKEND=x11 /usr/bin/darktable %U. Also remove the line start with TryExec.

Uninstall:

To remove darktable, simple run command in a terminal window:

sudo apt remove --autoremove darktable

And, remove the Ubuntu PPA by either removing source line in ‘Software & Updates’ utility under ‘Other Software’ tab, or running command:

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

If you would like to revert back the stock Darktable package in system repository, just purge the PPA instead of removing it as well as the software packages and install old version back.

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

How to Install FFmpeg (6.1 Updated) via PPA in Ubuntu:

As many users reported, the Rob Savoury’s PPA seems broken due to dependency issue.

So, I upload the  FFmpeg 6 and its dependency libraries into this unofficial PPA for those need FFmpeg 6.

NOTE: 1. The PPA so far is for Ubuntu 22.04 only!
NOTE: 2. The packages seem working good in my case. But it may or may not work for you! Use it at your own risk!

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

sudo add-apt-repository ppa:ubuntuhandbook1/ffmpeg6

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

2. For Linux Mint 21, you need to manually refresh package cache after adding PPA. To do so, run command:

sudo apt update

3. Finally, run the command below to either install or upgrade to FFmpeg 6.1:

sudo apt install ffmpeg

In case of in-complete installation, it’s HIGHLY recommend to run sudo apt upgrade to upgrade all the packages to the latest versions.

4. After installation, run the command below in terminal to verify:

ffmpeg --version

How to Downgrade FFmpeg library:

In case you want to downgrade the FFmpeg library to the stock version available in system repository. Open terminal and run command:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/ffmpeg6

NOTE: Keep an eye on terminal output before answering yes to confirm! It MAY remove some other useful app packages.

Show User Name in Top-bar in Ubuntu 22.04 | 24.04

Last updated: September 2, 2024 — Leave a comment

Want to display your username in the top panel? It’s easy to do this job in Ubuntu, Fedora Workstation and other Linux with GNOME Desktop via an extension.

After following this tutorial, you’ll see your username appear in the far right corner in top panel, just like the screenshot below shows you:

1. First, open Ubuntu Software, search for and install Extension Manager app.

Install Extension Manager in Ubuntu Software/App Center

2. Then, press Super (Windows Logo) key on keyboard to open the overview screen. Search for and launch Extension Manager.

3. When the tool opens, navigate to ‘Browse‘ tab. Finally, search for and click install “Add Username to Top Panel” extension. The extension so far supports for GNOME from v3.12 to 46. Meaning almost all Linux with recent GNOME are supported!

After installation, your username should appear immediately on top panel. To remove it, go back “Installed” tab, then either turn off or remove the extension.

For other Linux, e.g., Fedora Workstation, Arch, Debian, RockyLinux with GNOME, go to this page in web browser and use the ON/OFF switch to install it.

Another Choice: The extension mentioned above, so far does NOT support placing user-name to the extreme right. As workaround, you may search & install “Whoami in top bar” extension instead. Which, supports GNOME 45/46 so far (Ubuntu 24.04, Fedora Workstation 39/40).

After installed the extension, switch back to “Installed” tab, then you may click the setting icon for that extension to configure the position to left, center, or right, as well as relative position.

GIMP 2.10.34 is out! JPEG-XL Export & 3.0 Dev Backports [Ubuntu PPA]

Last updated: March 1, 2023 — 13 Comments

GIMP image editor released a new update for the 2.10 series few days ago! Here are what’s new and how to install guide for Ubuntu Linux users.

GIMP 2.10.34 is a new stable release features a lot of bug-fixes and a few enhancements. The official announcement is NOT ready somehow at the moment, though it’s released in gitlab project age. And, the source code is available to download at FTP web page.

For macOS, the DBus is now fully disabled as it in some cases could even cause app freeze. Open With feature still work fine, but other features using dbus (such as opening files or running batch commands from a separate GIMP process) won’t work. As well, check for updates function in macOS now works again.

The release also has some backports from the 2.99.x development releases. The “Canvas Size” dialog has been redesigned to use more horizontal space. And, it has new Template selector in resize dialog.

For PDF with transparent area, there’s new “Fill transparent areas with white” option which enabled by default on file import. And export dialog has “Fill transparent areas with background color” option to decide whether use transparent background.

Other changes in GIMP 2.10.34 include:

  • Symmetry dockable contents is now shown, yet deactivated, when no images are opened
  • Color scale preferences are now remembered across sessions.
  • Import JPEG-XL metadata support.
  • Export JPEG-XL support, always in 8bit lossless.
  • New header with “visible” and “link” icons in item dockables
  • Clipping layers better supported when importing PSD files
  • Paths are now exported to PSD
  • New option “Show reduced images” when loading TIFF images
  • 16-bit per channel export for raw image data

How to Install GIMP 2.10.34 in Ubuntu Linux

Option 1: Flatpak

GIMP provides official Linux packages through universal Flatpak package, though it runs in sandbox environment.

Ubuntu user can press Ctrl+Alt+T on keyboard to open terminal, and run the following 2 commands one by one to install it:

  1. Make sure the flatpak daemon installed by running command: 
    sudo apt install flatpak

  2. Then, install GIMP as Flatpak via command: 
    flatpak install https://dl.flathub.org/repo/appstream/org.gimp.GIMP.flatpakref

Once installed, start it either from app launcher or run flatpak run org.gimp.GIMP in terminal.

Option 2: Ubuntu PPA

For those prefer the classic .deb package format. I’ve uploaded the package into the unofficial PPA, with support for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10.

  1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add PPA: 
    sudo add-apt-repository ppa:ubuntuhandbook1/gimp
  2. Then either upgrade GIMP using Software Updater, or run command in terminal to install it: 
    sudo apt install gimp libgegl-0.4-0 libbabl-0.1-0

    For Linux mint, you may need to run sudo apt update to update package index first.

Uninstall GIMP:

For GIMP package installed as Flatpak, open terminal (Ctrl+Alt+T) and run command to remove it:

flatpak uninstall --delete-data org.gimp.GIMP

Also run flatpak uninstall --unused to clean useless runtime.

For .deb package from PPA, open terminal and run command:

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

The command above will remove PPA and downgrade the GIMP package into stock version in system repository.

For choice, you may remove the PPA instead by running command:

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

And remove the GIMP image editor via:

sudo apt remove --autoremove gimp libgegl-0.4-0

Control Screen Brightness for External Monitor in Ubuntu (GUI & CLI)

Last updated: November 5, 2023 — 3 Comments

Want to control screen brightness, color preset, contrast etc for your external monitor connected in Desktop PC or laptop? Here’s how to do the trick in both graphical and command line ways in Ubuntu & other Linux!

I know there are physical buttons to do the job. But for lazy men and/or software developers, few mouse clicks and/or a single command can be more effective. And ddcutil is the tool for Linux users.

ddcutil is a free and open-source tool that uses DDC/CI protocol to control settings for most external monitors. It also support some monitors (e.g. Eizo ColorEdge, Apple Cinema) through USB.

NOTE: Most modern monitors support DDC/CI protocol, but it may NOT enabled by default. Check the menu via the physical buttons.

Step 1: Install ddcutil & ddcui

The ddcutil package is available in most Linux’s system repositories, including Ubuntu, Arch Linux, Fedora, Debian. User can directly search for and install it from system App Store (Software App, Package Manager)

The package in Ubuntu repository is however always old. For the most recent version, there’s an official PPA maintained by the software developer, so far with support for Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 22.10.

    1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to add the PPA: 
      sudo add-apt-repository ppa:rockowitz/ddcutil

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

    2. After adding PPA, update system package index via command: 
      sudo apt update
    3. Finally, install the command line utility and graphical interface by running command: 
      sudo apt install ddcui ddcutil

Step 2: Control brightness & other monitor settings via Graphical tool

After installation, search for and open “ddcui” from Activities overview or start menu depends on your desktop environment.

NOTE: for “error access: permission denied” issue, either start the app via sudo ddcui command, or run command to add current user to i2c group (need system restart):

sudo gpasswd --add $USER i2c

When the app starts, choose your monitor (if more than one available) from the drop-down box.

Then go to menu View -> Features. There you’ll see the options to control screen brightness, color preset, contrast, RGB colors, clock, restore factory, etc settings!

Step 3: Control Monitor Settings from Command line

For those who are familiar with Linux commands, things can be done via following steps. NOTE: sudo is NOT required after adding user into i2c group and reboot.

1. First, open a terminal window and run command to report all connected monitors:

sudo ddcutil detect

In my case, I have built-in laptop display and external “Display 1”.

2. Then query the monitor’s capabilities string, for display 1 (-d 1) in my case:

sudo ddcutil -d 1 capabilities

In the screenshot, I added grep option to filter the ‘Brightness’ and the output code 10 is what I need.

3. Get the current value of feature code 10 (“brightness” in the case) for display 1:

sudo ddcutil -d 1 getvcp 10

3. Set the brightness level (code 10) to 60 for example:

sudo ddcutil -d 1 setvcp 10 60

Besides settings brightness to custom level, you may also increase or decrease brightness via ‘+’, ‘-‘ options. For example, increase brightness (code 10) with level 5 up.

ddcutil -d 1 setvcp 10 + 5

Or decrease brightness with level 5 down:

ddcutil -d 1 setvcp 10 - 5

This can be useful for binding to keyboard shortcut for controlling your monitor brightness. For more options, read the man page by running man ddcutil command in terminal.

The project does not provide official binary packages. Besides building from the source tarball, XUbuntu, Linux Lite, Linux Mint, and of course other Ubuntu based systems can get it from this unofficial PPA.

NOTE: Parole seems not working good in GNOME desktop with Wayland session. Meaning Ubuntu and Fedora workstation with default desktop environment need to switch to classic Xorg for this app.

1. First, press Ctrl+Alt+T on keyboard or search for and open terminal window from start menu. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

Type user password (no asterisk feedback) when it asks and hit Enter to continue. The PPA support for Ubuntu 20.04 and higher with both amd64 and arm64/armhf cpu architecture types.

2. Some Ubuntu based systems may need to manually update package index after adding PPA. To do so, run command:

sudo apt update

3. Finally, either upgrade the media player from an existing version (if any) using Software Updater (Update Manager), or run command in terminal to install it:

sudo apt install parole

Add “Auto Brightness” ON/OFF Switch in Ubuntu 24.04 System Menu

Last updated: May 7, 2024 — Leave a comment

For Ubuntu 24.04, Fedora workstation 39/40, Arch, Manjaro, etc, with GNOME desktop 43 ~ 46, there’s now an extension to add “Auto Brightness” toggle button in quick settings (aka system menu).

Meaning user don’t have to open System Settings and go to Power page again and again to turn on/off the function. Just open the top-right corner system tray menu, there’ll be a toggle button to quickly turn on/off auto brightness just like on a smartphone.

NOTE: Your laptop MUST support auto brightness feature and have GPU driver properly installed. To verify, just open System Settings and find out if there’s Automatic Screen Brightness option under Power tab.

How to Install the Auto Brightness quick menu button

The extension so far supports GNOME from version 43 to 46. It is available in EGO, which however lack of update for recent GNOME versions. If you want this quick toggle button, then it’s easy to install from the source tarball.

1. First, click the link below to download the source tarball.

Download Auto Brightness Extension

For choice, you may go to the Github project page for the source code.

2. After downloaded the source package, do following steps one by one to install it:

  • Extract the downloaded package, and navigate to the extracted folder.
  • Open another file window and navigate to .local/share/gnome-shell/extensions directory.
  • Finally, drag and drop the sub-folder from extracted folder to new opened window.

Tips: .local is a hidden folder, you need to press Ctrl+H to view (and press again to hide) in file manager. The gnome-shell and extensions sub-folders may NOT exist under ‘.local/share‘ if this is the first extension you’re going to install. Just create manually.

3. Next log out and back in.

Install either GNOME Extensions or Extension Manager from App Center (filter by Debian package), and launch it. Finally, turn on the “Auto Brightness Toggle” extension for displaying the new button in top-right system status menu.

Uninstall:

As the last screenshot shows you, in “Extension Manager” window just click the up/down arrow beside the toggle switch. Then, you’ll see the ‘Remove’ button for removing the extension.

Alternatively, you may delete the theme folder under .local/share/gnome-shell/extensions directory, and log out and back in to apply.

Audacious Music Player 4.3 Beta added PipeWire output & Opus Support

Last updated: March 6, 2023 — Leave a comment

The lightweight audacious music player announced the beta release of the next v4.3 a few days ago.

Usually, the final release will be out in next or next few months with mostly no change since beta. So far, this beta release include the following new features.

The new release added plugin support for Pipewire, which is a low latency sound server that is default in Ubuntu since 22.10.

Also, it added a plugin for Opus audio decoding support. Though it previously supports Opus through FFmpeb library compiled with --enable-libopus.

Audacious 4.3 also added again GTK3 as well as Qt6 support. In current v4.2 stable, I prefer to use Qt UI since GTK2 interface looks ugly due to incorrect icon size.

However, Qt UI lacks automatic light and dark mode switch depends on system color scheme in GNOME (default desktop environment in Ubuntu). With the new GTK3 build, it now looks good in my case in Ubuntu 22.04 with better integration.

Audacious 4.3 GTK3 UI

Other changes in Audacious 4.3 Beta include:

  • Implement Meson build system.
  • Allow copying file path in song info dialog
  • Support Ogg FLAC audio streams
  • Support reading embedded lyrics tags
  • Support new song length database format in SID plugin
  • Increased M3U file size limit from 16 MB to 256 MB
  • Support Publisher and Catalog Number tags
  • Add file filter to Export Playlist file dialog
  • Removed alarm plugin due to serious bugs

How to Get Audacious 4.3 Beta:

Audacious website provides the Windows EXE and source code for downloading at the link below:

Download Audacious

For all current Ubuntu releases, including Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, just open terminal (Ctrl+Alt+T) and run the commands below one by one to install it:

sudo add-apt-repository ppa:ubuntuhandbook1/apps
sudo apt update
sudo apt install audacious audacious-plugins

New PPA for Installing Transmission 4.0.4 in Ubuntu 22.04 | 20.04 | 23.10

Last updated: November 28, 2023 — 21 Comments

The Transmission BitTorrent client released version 4.0.0 a few days ago. Here’s PPA repository contains the package for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 23.10, Linux Mint 21/20.

According to the release note, transmission 4.0 features new C++ and gtkmm code-base, with much less CPU and memory usage than before. It also adds support for using BitTorrent v2 and hybrid torrents, support for IPv6 blocklists, and more.

How to Install Transmission 4.0.4 via Ubuntu PPA

I’ve built the new release packages into this unofficial PPA for Ubuntu 20.04 and higher. Ubuntu 18.04 is not supported due to dependency library version mis-match.

The new web user interface depends on NPM (Node.js package manager). It requires internet connection while building process, but launchpad build farm does NOT have. Meaning so far the PPA package does not include new web UI via JavaScript, but the old web user interface for remote control is stilling working in my case in Ubuntu 22.04.

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

sudo add-apt-repository ppa:ubuntuhandbook1/transmission

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

2. After adding the PPA, you can then launch Software Updater (Update Manager) and upgrade the system pre-installed transmission package to the new 4.0.0 release.

For Ubuntu based system without the BitTorrent client pre-installed, you may run command below to install it:

sudo apt update && sudo apt install transmission-gtk

You may replace transmission-gtk with (or add) following package:

  • transmission-qt – Qt user interface for KDE, LXQt, etc.
  • transmission-cli – command line interface.

Uninstall Transmission 4.0.4

You can choose to downgrade the BitTorrent client to system pre-installed version, by running command in terminal:

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

Or, remove the software packages instead by running command:

sudo apt remove --autoremove transmission-gtk transmission-qt transmission-cli transmission-daemon

And remove the PPA repository either via “Software & Updates” tool by removing the source line under “Other Software” tab, or by running command:

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

That’s all. Enjoy!
