The Beta release of Ubuntu 24.10, code-name Oracular Oriole, is out last night on Sep 20.
This is a short-term release with 9 months support. It so far features Linux Kernel 6.11 and GNOME 47 desktop.
To celebrate the 20th anniversary, the new release includes a “Warty Brown” accent color and new optional wallpapers in the “Appearances” settings page. There’s also an anniversary logo that you can see in the login screen.
And, the release now by default plays the original startup sound at login. While, there’s a toggle option in “Sound” settings page to turn it off.
The sound comes from the warty-startup.oga file under “/usr/share/sounds/Yaru/stereo” directory. Without logging out and back in, you may run command below in terminal to play it out:
/usr/bin/canberra-gtk-play --id="warty-startup"

When launching some apps (e.g., GParted, Synaptic, or Grub Customizer), install/uninstall packages with App Center or Software Updater, it always pops-up a dialog asking for admin password to authenticate.
This is great for security! But for lazy men those who don’t want to type user password again and again after logged in (or unlocked screen), it may be OK to disable the authentication window when using their computers at home or other safe places.

If everything goes well, the new GNOME 47 desktop will be default in upcoming Ubuntu 24.10 and Fedora Workstation 41, and optional in Arch, Manjaro Linux, etc.
The new release features accent colors in the “Appearance” settings page. With it, user can change the Default Blue color of toggle buttons, slide bars, check-boxes, selection borders, etc., as easy as a single mouse click.
Ubuntu has the feature since 22.04. It has 10 colors while GNOME 47 has 9. They include Blue (default), Teal, Green, Yellow, Orange, Red, Pink, Purple, Slat. And, so far the accent color does NOT apply to the folder icons.

Linux Kernel 6.11 was released! Linus Torvalds announced it 2 days ago on Sunday:
“I’m once again on the road and not in my normal timezone, but it’s Sunday afternoon here in Vienna, and 6.11 is out.
The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small. Nothing in particular stands out – the biggest patch in here is for Hyper-V Confidential Computing documentation. …”
This tutorial shows how to enable floating top panel in Ubuntu 24.04, Fedora 40, Arch, Manjaro and other Linux with GNOME 46/47 Desktop.
Unlike traditional system panel which is usually stick to screen edge, floating bar (or panel) looks kinda like a desktop widget. It floats on the desktop, and usually has a small distance from the top or bottom edge.
Some systems, such as Windows 11, Zorin OS, Deepin Linux, include options to enable floating taskbar. The KDE Plasma 6 desktop even use it as default, which also automatically switches to solid panel style, when a window approaches or is maximized.
Ubuntu is working on a new desktop security center and prompting-client. Here’s how to try it out in current Ubuntu 24.04 LTS.
It’s an experimental new feature that will land in next Ubuntu 24.10. Which, provides graphical interface to make it easier for users to control the file/folder access permission for Snap apps.
For example, when browsing web via Firefox (the preinstalled Firefox is a Snap package). You found a good image and want to save it to local folder, or you just want to download something. Before the downloading process starts, it will pop-up a dialog as the screenshot shows you, asking for user permission to allow writing to the file or folder.
