For vital subcomponents of Ubuntu – and its derivatives – you needn’t await the subsequent launch to look. You possibly can improve main components on the fly.
Right here at Vulture Towers, we’re engaged on a overview of a machine with a Twelfth-generation Intel chip, and that is induced points in some Linux distros. Again in 2021, we reported on work on kernel 5.16 to add Alder Lake support. Ubuntu 22.04 LTS shipped with kernel 5.15, although. The newest launch, 22.10, includes the ageing kernel 5.19, which you additionally get within the newest replace to “Jammy”, 22.04.2.
Kubuntu 22.10 comes with kernel 5.19, which is already previous its finish of life
In each 22.04 and 22.10, we skilled points on our Alder Lake field: beneath Wayland, flickering bands of noise throughout the display, and beneath X11, sluggish, hesitant mouse pointer motion. More moderen distros, corresponding to openSUSE Tumbleweed, had no such issues with kernel 6.1 or 6.2. The excellent news is that it is fairly straightforward to improve simply your kernel with out the trouble of updating to a brand new model of the entire OS… and kernel upgrades maintain the earlier model round (till you run sudo apt autoremove, anyway), so if one thing does not work proper, you may reboot into the previous kernel and take away the brand new one. It is pretty protected.
One possibility is to install a third-party kernel such as Liquorix. That is easy, and different kernel builds corresponding to this or XanMod are performance-tuned for desktop use.
The Mainline software makes it straightforward to choose the upstream kernel you need – and the completely different icon makes the inventory kernels simply distinguishable
You are able to do it with out leaving the relative security of Ubuntu itself, although, through the Mainline PPA. That is Ubuntu’s model of the present, upstream kernel, with out the modifications that Canonical usually makes. It really works high quality, and just about all applications should not discover any distinction in any respect, however heed the warning on that web page:
The steps are fairly straightforward, and several other sites will stroll you thru it. All you do is add the repository:
sudo add-apt-repository ppa:cappelikan/ppa
Refresh the bundle record, as regular:
sudo apt replace
Then set up the brand new mainline software, which places a pleasant graphical wrapper round selecting which kernel to put in:
sudo apt set up mainline
As soon as it is put in, run it out of your app launcher – its full title is the Ubuntu Mainline Kernel Installer – and you’ll select your required kernel. It does the remainder: downloads it, installs it, provides it to your GRUB boot menu, and then you definately simply reboot to attempt it. In testing, we discovered that it made all the problems with 5.15 and 5.19 vanish on our Alder Lake field. X11 grew to become completely clean, and all of the graphical glitches in Wayland vanished. (Only for reference, they did with the Liquorix kernel as properly, and we could not see any distinction in efficiency.)
Presto, a couple of minutes later, our Kubuntu (digital) field is working the most recent and best kernel 6.2
If you happen to do not see any profit, the Mainline software makes it straightforward to return to any particular older model, or again to the inventory kernel when you favor, and there may be steering on set up in some of the tutorials, too.
KDE Plasma
For the screenshots on this story, we selected Kubuntu to be able to display one other straightforward improve. KDE Plasma 5.27 is out, and it is expected to be the final release in the KDE 5.x series – KDE Plasma 6 ought to arrive sooner or later, nevertheless it’s not but clear when. As such, Plasma 5.27 is a long-term assist launch, so it is value upgrading to it. If you happen to do not need to wait, you may set up it now on Kubuntu 22.10. The process is far because it was once we described how to install Plasma 5.25 on Kubuntu Jammy. Simply add the Kubuntu-backports PPA:
sudo add-apt-repository ppa:kubuntu-ppa/backports
Then do a full improve, nevertheless you usually favor to do that.
It takes moderately longer, however after getting into one line and a few clicks, Kubuntu is working the final Plasma 5 desktop
There’s additionally an experimental construct for Kubuntu 22.04, though it is not advisable for manufacturing use simply but. We suspect {that a} extra full model might but observe, although.
No less than one Ubuntu remix, Tuxedo OS, already has it. We looked at Tuxedo OS 1.0 in October, and Tuxedo Computer systems has now released Tuxedo OS 2.0, with kernel 6.1 and KDE Plasma 5.27 – so it definitely will be made to work on the premise of Ubuntu Jammy. If you happen to’re able to do a clear set up, that is an possibility that is out there proper now. ®
