Ubuntu 22.10 (Kinetic Kudu) is an impressive release that includes new quick toggles, application spread, and other features.
Ubuntu 22.10 has been released, this article will take you to understand the new changes in Ubuntu.
Ubuntu 22.10 includes the new 5.19 Linux kernel, which includes the following features:
- To speed up the game, the new futex waitv() system call can make the game wait for multiple futex with a single system call.
- A task scheduler that supports CPU clusters that share L2/L3 caches (spreading tasks across clusters will result in more memory bandwidth and less cache contention).
- Intel® AMX (Advanced Matrix Extensions) instructions are supported.
- CO-RE support improves the portability of compiled BPF programs.
- More rapid random number generator (entropy extractor switched from SHA1 to BLAKE2s).
- Active reclamation is permitted in memory control groups.
- Intel® Trusted Domain Extensions support (TDX).
Note that this is the last release of the Linux 5.x series, as Linux Kernel 6.0 is the next release upgrade.
Changes in appearance are always the first to be noticed. This is especially true of Ubuntu 22.10, thanks to the significant improvements brought about by GNOME 43.
The new quick settings menu replaces the old, clunky system menu. This new feature, similar to the menus in Android, iOS, and Windows 11, allows you to turn Wi-Fi and Bluetooth on and off without having to open the Settings app.
and a brand new wallpaper.
GNOME has been updated with new features and bug fixes from the most recent GNOME release, GNOME 43.
- To improve performance and upgrade style, many applications have been converted to GTK4 and libadwaita.
- Nautilus, the default file manager, has been upgraded to GTK4. Because the Nautilus extension API has changed, all Nautilus extensions that have not been updated for the new version will fail.
- The GNOME text editor is now the default text editor application. It is still possible to install gedit.
- GNOME Terminal remains the default terminal application, but the GNOME console can be installed.
- The To-Do app is no longer pre-installed. It can still be installed, but the name has been changed to Endeavor.
- The GNOME Books application has been retired. Foliate is a recommended alternative application.
Although it is not an application that most people use on a daily basis, system settings are an essential part of the GNOME experience. With that in mind, it’s great to see it get a major visual overhaul, as well as GTK 4 and Libadwaita porting.
Another change to the settings menu is the addition of a new “Ubuntu Desktop Settings” menu item. This provides a centralized location for customizing and changing all Ubuntu-specific settings.
- Default audio server is now PipeWire instead of PulseAudio
- Default image app now supports .webp format
Ubuntu 22.10 will be supported for 9 months until July 2023. If you need long-term support, I recommend Ubuntu 22.04 LTS
