Linux Kernel 6.6 Now Easy to Install in Ubuntu 22.04/20.04 via Zabbly Repository

Last updated: November 13, 2023 — Leave a comment

For those who want to install the most recent Kernel 6.6 with new hardware support or compatibility fixes, it’s now available in the zabbly repository for Ubuntu 20.04, Ubuntu 22.04, and Debian 12.

Linux 6.6 was released few weeks ago as the latest Kernel series. It features PSR power saving for Intel 4th/5th CPU, initial PECI support for 4th Gen Xeon, initial support for the Intel Lunar Lake VPU4, Dynamic Boost Control support for AMD Ryzen laptops, as well as various new hardware support. See HERE for more.

As Ubuntu Mainline Kernel PPA is stuck at old RC5 for unknown reason, there’s NO official package for the new Kernel release.

For choice, the Zabbly repository maintained by Ubuntu core developer (quit a few months ago) has updated the new kernel package for Ubuntu 22.04 & 20.04.

Add Zabbly Repository & install latest Kernel

Press Ctrl+Alt+T on keyboard to open terminal. Then, run the commands below one by one to add the repository and install latest Kernel:

  • Download & install the key: 
    sudo wget -O - https://pkgs.zabbly.com/key.asc |sudo tee /etc/apt/keyrings/zabbly.asc
  • Setup the repository via single command: 
    sh -c 'cat <<EOF > /etc/apt/sources.list.d/zabbly-kernel-stable.sources
Enabled: yes
Types: deb
URIs: https://pkgs.zabbly.com/kernel/stable
Suites: $(. /etc/os-release && echo ${VERSION_CODENAME})
Components: main
Architectures: $(dpkg --print-architecture)
Signed-By: /etc/apt/keyrings/zabbly.asc

EOF'

    This is a single command for Ubuntu/Debian. For their based systems, you have to replace $(. /etc/os-release && echo ${VERSION_CODENAME}) with jammy (for 22.04 base), focal (for 20.04 base), or bookworm for Debian 12 base.

  • Finally, update & install the new kernel: 
    sudo apt update
    sudo apt install linux-zabbly

In case the previous steps are not clear enough, or it broke things up, see this step by step detailed guide instead.

And, there are tons of other changes and bug-fixes, see the release page for details.

How to Install OBS Studio 30.0 in Ubuntu

The release page (see the link above) provides Windows .exe, Mac OS .dmg, and Ubuntu .deb packages for downloading under ‘Assets’ section.

For Ubuntu and Linux Mint, there’s also an official PPA available to make it easy to keep the software up-to-date.

The PPA supports the new release for Ubuntu 22.04, Ubuntu 23.04, Ubuntu 23.10, and their based systems. While, Ubuntu 20.04 does not longer supported due to FFmpeg version mis-match.

1. Firstly, 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:obsproject/obs-studio

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

2. Then, either use Software Updater to update the software package (if an old version was installed).

Or, use apt command to install/upgrade the software package:

sudo apt install obs-studio

NOTE: Linux Mint may need to run sudo apt update first to update package cache.

Once installed, search for and launch OBS Studio from ‘Activities’ overview or start menu depends on your desktop environment and enjoy!

NOTE: OBS Studio in Ubuntu 22.04 and higher with Wayland, looks kinda borderless, due to Qt theming issue. If you prefer the classic header-bar and window border, see this tutorial to enable xcb plugin

Uninstall OBS Studio

To downgrade the software to the stock version that your system repository provides, run command:

sudo apt install ppa-purge && sudo ppa-purge ppa:obsproject/obs-studio

Or, either open Software & Updates and remove the PPA source line under ‘Other Software’ tab:

or run command in terminal to remove the PPA repository:

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.

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,

  • 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.

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:

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

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.
