The new release added amdgpu panel power savings which uses dedicated hardware in systems with integrated Radeon graphics to decrease panel power consumption when the system is on battery.

This simple tutorial shows how to get rid of the “Mobile Broadband” menu option from the upper right system status menu in GNOME Desktop.
GNOME, the default desktop in Ubuntu and Fedora Workstation, has built-in support for mobile broadband. If your computer (usually laptop) has a built-in SIM card slot, then it will show you the “Mobile Network” page in Settings and “Mobile Broadband” option in upper right menu.
For those who rarely use this feature, the option is useless but makes the menu longer. So, it’s a good choice to completely disable it!
This simple tutorial shows how to install and enable the Classic Gnome 2 style desktop session in Ubuntu 22.04 and/or Ubuntu 24.04.
Though the title said for Ubuntu, this tutorial also works in Debian 12 & 11. Fedora, Arch, and their based systems also have corresponding packages for the similar job.
As far as I know, there are 3 ways to get back the classic Gnome 2 layout. They include:

The image viewer app varies depends on your desktop environment, the rotate options may be available other-where such as in app menu.
After rotated your image, either click Save (Ctrl+S) to override the original image file, or choose Save as (Ctrl+Shift+S) to save the rotated image as another file.

Wallpaper Contest for the next Ubuntu 24.04 LTS, Noble Numbat, is open! Top 8 winner images will be shipped in the iso image.
A bit different to the previous contests, this time the submissions are separated into 4 categories: Mascot Theme, Digital / Abstract Art, Nature, and Other. Each category will have 2 winners, and finally 8 mixed images will be made as optional wallpapers in Ubuntu 24.04 out-of-the-box.
The AI generated artwork is NOT allowed! Because there are active legal debates on the ownership of AI generated artwork and whether it can be copyrighted or not. And, many popular AI generation tools use a license that does not align with those for the contest.

Like Firefox, Thunderbird email client in Ubuntu is going to be replaced as a Snap app runs in sandbox.
Canonical, the company behind Ubuntu, is working on porting core apps to Snap package format in recent years. Firefox, Chromium (in system repository), and Ubuntu Software (App Center) are now Snap apps in current Ubuntu releases. Next will be probably Thunderbird!
Canonical has built Thunderbird as Snap package for a period of time. It’s a re-pack of the upstream binary, only available for amd64 (Intel/AMD CPUs), as alternative package for the pre-installed .deb package.
Just one day ago, the Ubuntu Desktop team announced that the Thunderbird Beta Snap now is building from source instead of repacking. Meaning it can be built on other CPU architecture types, such as arm64 and armhf.
And, the Thunderbird Snap built from source aims to be default in next Ubuntu 24.04 LTS.
We are aiming at using the snap built from source instead of the deb in Noble. (the reasons are the same than for Firefox, making it easier to roll new versions on older supported series and reducing the maintenance efforts).
Meaning in future, there will be (mostly) NO .deb package for the Thunderbird email client in Ubuntu repository!
Thankfully, those who prefer the classic .deb to Snap can use the Mozilla Team PPA instead, which is maintained by members from Ubuntu Developer Team.
For more about the Thunderbird package format transition, see it in discourse.ubuntu.com.
The Arduino team announced the 2.3 release of the Arduino IDE this Wednesday.
Since v2.3, the debug feature is now stable and fully incorporated into the IDE! It’s now based on a standard framework, and enabled for all the Arduino boards based on the Mbed™ core, include GIGA R1 WiFi, Portenta H7, Opta, Nano BLE and Nano RP2040 Connect.
Maintainers of Arduino cores can now add debugging for any board. And, the upcoming release of the Arduino-ESP32 core will support the new debug framework!
