Linux is used in all places, from supercomputers to servers and on Web of Issues (IoT) units and the cloud. The one place the place Linux is not in all places is the desktop — and that is in no small half as a result of the foremost Linux industrial distributors, equivalent to Purple Hat and SUSE, do not prioritize the desktop. Canonical, Ubuntu Linux’s mum or dad firm, nevertheless, does deal with the desktop. And its newest launch, Ubuntu 23.10, underlines this prioritization.
As my fellow ZDNet Linux desktop fan, Jack Wallen, remarked in his early evaluation of Ubuntu 23.10, “there’s greater than meets the attention” to the discharge. On this new model, which is a preview of the much-anticipated Lengthy Time period Supported (LTS) model, Ubuntu 24.04 LTS, there are some important enhancements.
Additionally: Which Ubuntu taste is greatest fitted to you?
These upgrades begin with Ubuntu 23.10 being primarily based on the brand-new Linux 6.5.0 kernel. As well as, the default desktop is GNOME 45, which comes with a brand new workspace indicator and full-height sidebars.
Up to now, so good. Nonetheless, you will most likely need to replace GNOME as quickly as you put in Ubuntu 23.10. The rationale for that replace is as a result of there is a newly found and critical GNOME safety bug, CVE-2023-43641. Hidden inside GNOME is an obscure library program, libcue, that is used for CD metadata. That ‘CD’ does not relate to Linux’s change listing command, however to the compact discs we use to play music and set up software program.
Whilst you’ve nearly definitely have by no means heard of libcue, it is really invoked on a regular basis in GNOME. It seems that for those who obtain a malicious CUE file, it may be used to assault, crash, or take over your PC. I hate taking possibilities with my desktop, and neither must you — so use the repair.
The Ubuntu Desktop 23.10 additionally introduces a brand new App Heart, changing the earlier Ubuntu Software program. Developed utilizing Flutter and snap packages, this App Heart presents a seamless solution to handle each old-school Linux deb and new-wave snap packages.

Moreover, a brand new Rust-based ranking service guarantees dynamic methods to find apps primarily based on person scores and snap metadata. You may consider it as a desktop app retailer, and I am discovering it fairly useful.

A associated change is that the App Heart will even be dealing with firmware updates, Beforehand, the method that checked firmware ran completely within the background and ate up quite a lot of system assets. Now, the background course of is far lighter and a single objective will handle all of your hardware-related updates.
Turning to safety, apart from the mouthful that’s “restricted unprivileged person namespaces,” Ubuntu 23.10 comes with an experimental encryption characteristic: Trusted Platform Modules (TPMs)-based Full Disk Encryption (FDE). Not like conventional FDE, which depends on passphrases, TPM-backed FDE shops the decryption key within the TPM chip — in case your pc has one. This strategy ensures your information’s safety, even when the boot course of is compromised.
These options are all neat, however the place Canonical actually exhibits that it is taking the desktop critically is by enhancing its administrator capabilities. The brand new Ubuntu Professional service, which is free for as much as 5 PCs, helps you to handle a number of workplace or residence desktops.
As well as, ADsys, the Energetic Listing Group Coverage Object (GPO) shopper, can handle your networking configuration for each Ubuntu and Home windows desktops. For hobbyists, this addition does not actually matter, however if you wish to use the Ubuntu Linux desktop in a enterprise, it is a large deal.
Directors can even now use Subiquity and cloud-init to customise desktop pictures for workplace set up. So, for instance, you possibly can routinely arrange a number of desktops with their community configuration, person information, SSH keys, put in software program applications, and you too can run scripts. This course of, as soon as once more, makes establishing an workplace of desktops very straightforward.
Additionally: Find out how to set up Ubuntu Linux (It is easy!)
In relation to new techniques, there’s additionally been a change within the default set up whenever you first arrange Ubuntu. As an alternative of putting in the bottom system — together with such Linux desktop standbys because the Firefox internet browser, the LibreOffice workplace suite, and the Thunderbird e-mail shopper — you begin with solely the naked minimal.
The thought is to supply new customers with a brand new, skinny desktop. They will then determine which applications they need on their desktop, moderately than the baker’s dozen of applications that include the outdated, full set up bundle. Customers can then use the brand new and improved App Heart to put in solely the applications they need. If, nevertheless, you continue to need all the things and the kitchen sink, you possibly can set up it that method, too.
Put all of it collectively and the brand new Ubuntu appears fairly darn good. Particularly, for those who’re a enterprise person who’s been excited about utilizing the Linux desktop within the workplace, kick the tires of this model. I feel you will be impressed.
