Segment 1 (Deep Dive)

  • Jammy Jellyfish - Ubuntu 22.04 LTS

  • Topics

  • What’s new (from the Ubuntu Blog https://lhs.fyi/zo )?

  • Linux desktop performance has had a massive upgrade for this release. Thanks to work on GNOME triple buffering, Intel and Raspberry Pi graphics drivers will now see up to double the frame rate when navigating the desktop. We also see significant improvements when using AMD and NVIDIA graphics cards as well as runtime power management for NVIDIA GPUs. Wayland is now the default display server for most systems, whilst X11 remains the default for those with NVIDIA GPUs.

  • GNOME 42 also brings new power profile options, allowing users to choose between performance and power consumption from the settings screen.

  • As always, Ubuntu comes with a host of other tweaks and updates in addition to these headline features.

  • PulseAudio delivers a number of improvements for Bluetooth headsets, with support for a wider range of devices and battery level reporting.

  • LibreOffice, Thunderbird and Firefox have all been updated to the latest versions. And Firefox now ships as a snap, published by Mozilla.

  • Developers also have access to the latest toolchains for Python, Ruby, Perl, Go, PHP and now Rust. Rust is a new addition for Ubuntu 22.04 LTS, supporting memory-safe, systems-level programming.
