Changes in the new release include:

  • PTBatcherGUI can now also queue user defined assistant and user defined output sequences.
  • PTBatcherGUI: Added option to generate panorama sequences from an existing pto template.

I also sync the packages into the apps PPA, use either one as you prefer.

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

sudo add-apt-repository ppa:ubuntuhandbook1/hugin

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

2. Update system package cache for Ubuntu 18.04 and Linux Mint, though it’s done automatically while adding PPA in Ubuntu 20.04+:

sudo apt update

3. Finally, either run the command below in terminal to install the panorama photo stitcher:

sudo apt install hugin

Or, upgrade the software (if an old version was installed) via Software Updater (Update Manager) app:

Uninstall hugin:

To remove the software package, simply run command:

Tilix Terminal Emulator 1.9.6 is out, how to Install via PPA

Last updated: November 14, 2023 — 4 Comments

Tilix terminal emulator released version 1.9.6 few days ago. Here’s how to install it in Ubuntu 22.04, Ubuntu 23.04, and Ubuntu 23.10.

Tilix is a tiling terminal emulator, which uses the VTE GTK+ 3 widget for various features, such as split horizontally or vertically, transparent background, background images, quake mode support, custom hyperlinks, experimental trigger and badge support.

The development of Tilix is moving slowly now due to lack of maintainers. The new 1.9.6 is released more than 20 months after the last stable. And, it only includes minor new features and bug-fixes:

  • Add close button to search box.
  • Replace variables in custom link commands
  • Follow system color-scheme for default theme-variant
  • Add compatibility with Nautilus 43
  • Avoid shell injection in open-tilix plugin
  • Fix GLib critical warnings on startup
  • Update to GtkD 3.10.0

Tilix search box has close button.

How to Install Tilix 1.9.6 in Ubuntu 22.04, Ubuntu 23.10

The new release provides prebuild package for Linux, which is available to download at the link below:

Download Tilix

It’s ‘tilix-1.9.6_x86_64-linux-gnu.tar.gz‘ for 64-bit modern PC and laptop. Just download the package, extract, and run the executable to launch the terminal emulator.

Ubuntu PPA

The official tarball does NOT include run-time libraries. You have to manually figure out “error while loading shared libraries …” errors.

To make the life easy, I’ve upload the new packages into this unofficial PPA, build against the rules from Debian Unstable. So far, it supports Ubuntu 22.04, Ubuntu 23.04, Ubuntu 23.10, on both x86_64 and AArch64(arm64).

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

sudo add-apt-repository ppa:ubuntuhandbook1/tilix

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

2. Linux Mint 21 users need to refresh system package cache manually, by either running the command below or using “Refresh” button in Update Manager:

sudo apt update

3. Finally, either run command to install the terminal emulator:

sudo apt install tilix

Or, update it through Software Updater (Update Manager) utility.

NOTE: Upgrading from v1.9.5 may cause following error pop-up at launch, but I don’t know how to correct the issue.

Thanks to @oswald_c, you may fix the issue by enabling ‘Run command as a login shell’ to enable it‘ option under default profile of “Preferences” dialog. See the screenshot below:

Uninstall Tilix

To downgrade Tilix to stock version in your system repository, open terminal (Ctrl+Alt+T) and run command to purge the PPA:

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

To uninstall Tilix, use this command instead:

sudo apt remove --autoremove tilix tilix-common

And, remove the Ubuntu PPA, either by running command in terminal:

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

or use “Software & Updates” to remove the source line under “Other Software” tab.

PPA Updated for Installing GIMP 2.10.38 in Ubuntu 24.04 | 22.04

Last updated: May 17, 2024 — 11 Comments

GIMP image editor announced a new stable release for the 2.10 series few days ago. Here’s how you can install it in Ubuntu 24.04, Ubuntu 22.04, Ubuntu 20.04, and Ubuntu 23.10.

First of all, GIMP 2.10.38 includes Windows Ink drivers support for better tablets support on Windows. It also backports some small features from GTK3 to GTK2, with some improvements for Windows users. They include:

  • Use native Windows API for converting keystrokes to characters,
  • Fix keyboard input when using IMEs,
  • Fix mouse events in presence of transparent windows on the desktop,
  • Win32 IME Fixes, and more.

Besides the improvements for Windows users, the release also includes various bug-fixes, including that GIMP crashes every time on exit in my case in Ubuntu 24.04. See release note for more about GIMP 2.10.38.

(Old content for GIMP 2.10.36) The new release also has some new features. They include Adobe Swatch Exchange (ASE) and Adobe Color Book (ACB) palettes support.

Gradient Tool now has an “FG to Transparent (Hardedge)” option, to generate a gradient from the foreground color to transparency, with hard-edge transitions between the 2 colors. Which, as well includes a “Repeat” option to alternate repetitive colored shapes.

Other changes in GIMP 2.10.36 include:

  • Load GIF images with PixelAspectRatio header metadata correctly.
  • Improve formatting behavior when selecting and changing text on canvas.
  • Add “Table of Contents” option under Help > User Manual submenu.
  • Workaround broken graphic tablet with recent linuxwacom driver on Linux.

How to Install GIMP 2.10.38 in Ubuntu

GIMP provides official Linux package through Flatpak. For choices, they are Snap package and Ubuntu PPAs (.deb) maintained by contributors.

Option 1: Flatpak (official)

Flatpak is an universal package format that can be installed in most Linux, though it runs in sandbox.

To install GIMP 2.10.38 as Flatpak, press Ctrl+Alt+T on keyboard to open terminal and run the 2 commands below one by one:

  • Install the Flatpak daemon package: 
    sudo apt install flatpak
  • Install GIMP Flatpak package: 
    flatpak install https://dl.flathub.org/repo/appstream/org.gimp.GIMP.flatpakref

If you already installed an old version of the Flatpak package, try to update it by running command:

flatpak update org.gimp.GIMP

Option 2: Snap package

Like Flatpak, Snap is also an universal Linux package format runs in sandbox environment. It’s easy to install by simply search & click installing in App Center (or Ubuntu Software for 22.04 & earlier).

Option 3: Ubuntu PPA

For those who prefer native .deb package format, I’ve upload the new release package into this unofficial PPA for Ubuntu 24.04, Ubuntu 22.04, Ubuntu 20.04, and Ubuntu 23.10, with amd64, arm64 and armhf support.

1. First, open terminal (press Ctrl+Alt+T) and run command to add PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/gimp

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

2. Linux Mint users need to manually refresh system package cache, though, it’s done automatically in Ubuntu while adding PPA. To do so, run command:

sudo apt update

3. Finally, either run command to install GIMP 2.10.38:

sudo apt install gimp gegl libgexiv2-2

For Ubuntu 20.04, also run sudo apt install libgexiv2-2 to update the runtime library. Or run sudo apt upgrade if GIMP refused to run after installation.

Or, use “Software Updater” (Update Manager) to upgrade your current GIMP to the latest.

Uninstall GIMP

If you installed GIMP via the official Flatpak package, run command below in terminal to uninstall it:

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

Also run flatpak uninstall --unused to remove useless runtimes.

For the Snap package, simply use Ubuntu Software or App Center to uninstall it.

For the PPA package, either run command to purge PPA and downgrade to the stock version:

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

Or, remove the image editor directly by running command:

sudo apt remove --autoremove gimp gimp-data gegl libgimp2.0 libbabl

Then, remove the PPA either via command:

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

or ‘Software & Updates’ tool under Other Software tab by removing the source line.

How to Dim Multiple or Individual Monitor in Ubuntu 22.04

Last updated: November 5, 2023 — Leave a comment

Have multiple monitors connected to your Ubuntu 22.04 machine? There’s now an indicator to dim all or individual monitor screen brightness with sliders.

You can dim external monitor brightness with either physical buttons or ddcutil utility. However, an indicator applet in system tray can be more effective, and here’s one for Ubuntu 22.04 with default GNOME 42.

It’s a Gnome Shell extension, that adds a light bulb to top-right corner in panel. By clicking on it, will show you the slider to dim all the connected monitors, as well as individual sliders to dim certain screens.

And, by moving the slider to far right will make the screen totally dark, just like being turned off.

Besides dimming monitor screens, it can also change the colors with RGB sliders, which also can apply to either all or individual monitors.

As my laptop’s external HDMI port is broken, I can’t try out the multi-monitor support. But, the dimming and RGB color (need to at least move dim slider a bit to right) functions are working very well in my case in Ubuntu 22.04 Desktop PC.

My test without multi-monitors

How to Install the Dimming Control Indicator

First, launch Ubuntu Software, then search for and install “Extension Manager” app.

Install Extension Manager in Ubuntu 22.04+

Then, click on top-left ‘Activities’ button to open overview screen, search for and launch ‘Extension Manager’.

When the tool opens, navigate to ‘Browse‘ tab, and finally search and install “VividShade: Multi-Monitor RGB Dimming Control” extension.

The indicator applet will appear on panel immediately after installation.

Uninstall:

To uninstall this extension, also launch “Extension Manager“. Click expand it under first tab, finally click on red “Remove” button.

NVIDIA 545.29.02 is out! Support Night Light for GNOME/KDE Wayland

Last updated: November 1, 2023 — 1 Comment

NVIDIA announced 545.29.02 graphics driver for Linux yesterday, as a new release series for its New Feature Branch Version.

For Ubuntu 22.04 + and Fedora Workstation with default GNOME on Wayland, as well as KDE on Wayland, the new driver adds support for the CTM, DEGAMMA_LUT, and GAMMA_LUT DRM-KMS CRTC properties, which, finally make the ‘Night Light’ and ‘Night Color’ feature work for NVIDIA users.

Night Light finally works on Wayland with NVIDIA driver

For desktop GPUs, the release adds initial experimental support for runtime D3 (RTD3) power saving mode. When all the PCI functions are idle, and all required conditions are satisfied, your GPU will go to the lowest power state resulting into maximum power savings.

The new driver also added experimental support for framebuffer consoles. On kernels with implement features, nvidia-drm will install a framebuffer console when loaded with both modeset=1 and fbdev=1 kernel parameters. Though, when an nvidia-drm framebuffer console is enabled, unloading nvidia-drm will cause the screen to turn off.

Other changes in NVIDIA 545.29.02 include:

  • Experimental HDMI 10 bits per component support
  • Support for virtual reality displays
  • CERTIFIED-quality support for GeForce and Workstation GPUs to open kernelmodules.
  • Support for PRIME render offload to Vulkan Wayland WSI
  • Support for HDR signaling
  • Add support to NVIDIA VDPAU driver for running in Xwayland
  • Support EGL_ANDROID_native_fence_sync EGL extension.
  • Support VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT
  • Support VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT

For more about the new driver, see the official release note.

How to Install NVIDIA 545 Driver

Ubuntu will build the new driver series and publish through official system repositories. So, just wait! It will be available in “Additional Drivers” utility when it’s ready.

For those who can’t wait, the “Graphics Drivers” team PPA has made the driver package for Ubuntu 20.04, Ubuntu 22.04, and higher.

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

sudo add-apt-repository ppa:graphics-drivers/ppa

Display Live Earth as Desktop Wallpaper in Ubuntu 24.04 | 22.04

Last updated: May 5, 2024 — Leave a comment

This simple tutorial shows how to display live earth as desktop wallpaper in Ubuntu 22.04 and Ubuntu 24.04.

Ubuntu has Wallch wallpaper changer in system repository, which has option to show live earth as wallpaper. However, the app is no longer updated and the feature is broken for all current Ubuntu releases.

If you’re interested in viewing high-resolution 3d real-time image of the earth in your desktop, then there’s another free open-source tool can do the job.

It’s liewa (Live Earth Wallpapers), that supports all known geostationary satellites for the high resolution sentinel images, Nasa Solar Dynamics Observatory images and NASA astronomy picture of the day (Apod)!

By default, it uses GEOS-16 satellite for the earth image, that display a small earth in center of your screen. Though, the app has setting options to add or edit satellites.

Add, configure satellites

So, you can have more than one real-time images of the earth from different satellites displayed on your screen at the same time, in different size, with either natural color or geocolor.

How to Install Live Earth Wallpapers (Liewa)

The tool provides .deb package for downloading in its Github releases page:

Download Liewa

After downloaded the .deb package, right-click on ‘Downloads’ folder and select “Open in Terminal”. Finally, run command to install it in pop-up terminal window:

sudo apt install ./liewa.deb

Finally, launch it from either start/applications menu or the overview screen depends on your desktop environment.

When the app window opens, configure canvas size, satellites, etc in first tab, then click on “Create New Scheduler” in Scheduler tab should start the live earth wallpaper.

Though, it takes quite a few seconds to apply, waiting for automatically start the service. If you can’t wait, try to open terminal (Ctrl+Alt+T) and run command to manually start the service:

systemctl status --user liewa

Uninstall:

You can stop the live earth wallpaper by clicking on “Delete Scheduler” button in app window, then set another wallpaper via ‘Background’ settings.

To remove the software, simply open terminal (Ctrl+Alt+T) and run command:

sudo apt remove --autoremove liewa
