Canonical Contributing Upstream Improvements To Plymouth Ahead Of Ubuntu 20.04 LTS

One of the immediate differences Ubuntu 20.04 desktop/laptop users will notice when booting in UEFI mode is the boot splash screen improvements thanks to leveraging Red Hat's work on providing a flicker-free boot experience and pulling in the UEFI BGRT system/motherboard logo during the boot process to provide a more transitive experience. Canonical in turn is working on pushing some of their improvements back into upstream Plymouth.

Dell XPS Ice Lake Taking A Wallop On Ubuntu 20.04

With our early benchmarking of Ubuntu 20.04 in its current nearing the end of development state, we've been seeing Ubuntu 20.04 boosting Intel Xeon Scalable performance, running well with AMD EPYC Rome, and good AMD Ryzen performance, among other tests. Strangely though the one platform where I've found Ubuntu 20.04 hard regressing so far is with the Dell XPS 7390 Ice Lake.

Trying Out Ubuntu 20.04 With ZFS + Zsys Automated APT Snapshots

As part of the ZFS improvements for Ubuntu 20.04 with Canonical's Zsys initiative is the ability to automatically take snapshots on APT operations for being able to do a system rollback/revert if necessary following package management changes. I've begun trying out the ZFS/Zsys changes for Ubuntu 20.04 and so far is working well.

Ubuntu 20.04 Atop ZFS+Zsys Will Take Snapshots On APT Operations

Ubuntu 20.04 is coming out next month and will be the first LTS release with Ubuntu desktop ZFS support available for the root file-system after it was made easy-to-deploy the Ubuntu desktop on ZFS last cycle. One of the areas being expanded upon with the ZFS support has been Ubuntu's Zsys daemon for offering extra functionality for ZFS-based setups.

Ubuntu 20.04 LTS Likely To Ship With Linux 5.4 As Opposed To 5.5

While the Linux 5.5 is out as stable today and Ubuntu 20.04 LTS isn't shipping until late April, it looks like they are settling on the use of the Linux 5.4 series, rather than the newer 5.5 and Linux 5.6 would be cutting too close to release anyhow for making this long-term support release.

Ubuntu 20.04 LTS Adds WireGuard Support

While WireGuard was merged into Linux 5.6, the Ubuntu 20.04 LTS release is currently tracking Linux 5.4 and for the April release is likely to be shipping with Linux 5.5 as the 5.6 release will be cutting it too close. But Ubuntu 20.04's kernel has now back-ported WireGuard.

A New Desktop Theme Is Coming For Ubuntu 20.04 LTS

With Ubuntu 20.04 to see installation on many desktops (and servers) given its Long-Term Support status, Canonical and the Yaru community team have begun working on a successor to the Yaru theme for this Linux distribution release due out in April.

Unity 8 Desktop On Ubuntu 20.04 LTS Could Take A Year Before Being Usable

While Canonical no longer develops their Unity 8 stack for Ubuntu, the UBports crew continues advancing Ubuntu Touch mobile as a community project and as part of that they do work on Unity 8 for their devices and desktop support. But if you're hoping to see Unity 8 running nicely on Ubuntu 20.04 LTS, that could be a while.

Ubuntu 20.04 LTS Could Better Support Scanners Compliant With Apple AirScan

Apple AirScan is akin to their AirPrint technology for supporting various printers from Apple devices without the need for specialized drivers. Multi-function printers compliant with AirPrint also need to implement AirScan for scanner functionality, thus opening up most of today's multi-function printers to supporting this scanning standard. Ubuntu 20.04 LTS could end up supporting AirScan nicely thanks to new SANE back-ends.

Ubuntu 13.04 vs. Ubuntu 20.04 Development Performance Comparison Without Mitigations

Last week I posted benchmarks looking at seven years of Ubuntu Linux performance in re-testing the releases of Ubuntu 13.04 through Ubuntu 19.10 stable and even the latest Ubuntu 20.04 LTS daily development image. A question that came up was how much better that performance would have been without any CPU vulnerability mitigations in place for Ubuntu 20.04... Well, here's that answer.

Ubuntu 19.10 Laptop Disk Encryption Benchmarks

A Phoronix Premium reader recently inquired about the performance impact of LUKS LVM-based disk encryption that continues to be offered by Ubuntu's Ubiquity installer on new installations and if it's worthwhile. As I've said for many years, it's certainly recommended for production systems -- particularly laptops where there are greater chances of theft -- and the performance impact isn't generally all that bad with modern CPUs and the likes of AES-NI.

Ubuntu's Mir Display Stack Accomplished A Lot In 2019 For Being Discounted Two Years Ago

It was back in April 2017 that Canonical decided they would abandon Unity 8 and switch back to GNOME. While Mir played a big role together with Unity 8, they continued working on Mir with staffing changes and a shifted focus of adding Wayland support and tailoring it for primarily IoT use-cases and tightly integrated with their Snap packaging concept. Two years later, Mir is still alive and earlier this month marked the release of Mir 1.6. Here's a look back at the Mir highlights for 2019.

Ubuntu 20.04 LTS Might Still End Up Shipping With WireGuard Support

There are early discussions going on over the possibility of shipping WireGuard support in Ubuntu 20.04 LTS that could be done either using the existing DKMS kernel module or patching their Linux 5.5-based kernel with WireGuard now that the necessary crypto API changes made it into that release.
