Ubuntu 22.04.4 arrives with Linux 6.5 as the main novelty

Ubuntu 22.04.4

Canonical releases a version of Ubuntu every six months, but in the Aprils of even-numbered years it gives us an LTS. The main version is directly supported for 5 years, while other flavors can be supported for 3. In all cases they are versions supported for longer, and the most recent is 2022. A few hours ago, Canonical released its fourth update, what matches Ubuntu 22.04.4. What doesn't change is his code name: Jammy Jellyfish.

When Debian gives us point updates of its operating system, in all its release notes it reminds us that these are not completely new versions and that it's not worth reinstalling The operating system. Everything in the new ISOs has come to existing installations in the form of an update. With Ubuntu 22.04.4 we are facing the same thing, a new ISO that can now be downloaded with which scratch installations will have the latest software that includes 22.04.

Ubuntu 22.04.4 activates support for new hardware

The most notable novelty that has arrived with Ubuntu 22.04.4 is its kernel, now Linux 6.5. It's part of Hardware Enablement (HWE), that is, when they update the kernel to be compatible with newer equipment that might otherwise perform less well. Among the rest of the news, we have:

  • New arm64+largemem ISO for ARM servers, including a 64k page size kernel, typically used for Machine Learning.
  • Fix for AMDGPU: Screen freezes with W7500.
  • Enables open NVIDIA kernel modules in the NVIDIA Graphics driver 515.
  • Realtek 8852CE WiFi 6E country code udpates for kernel 6.5.
  • Fixes sound for SoundWire-Audio Codec-ALC713 and SoundWire-Jack Codec-ALC713.
  • Fixed missing CS35L41 firmware for HP G11 mWS and Dell Oasis models.
  • Support for Intel Discrete Gale Peak2/BE200.
  • Fixed missing firmware for Intel CNVi AX211 on Intel Meteor Lake platform.
  • Fixed unwanted screen rotations on Dell laptops with KSUs 0CB2, 0CB3, 0CB4.
  • Added support for the AMD-Xilinx Kria KD240 board.
  • Fixed Dell dock station WD22TB4 losing dev ether after reboot/shutdown.

Ubuntu 22.04.4 can now be downloaded from the new page with the logo of Ubuntu 22.04 (link) or updating the operating system. The official flavors also offer the new ISO from their respective websites.
