KDE Plasma 5.17 Linux Desktop to Modernize the Settings, Add Many UI Changes One of the nicest changes to be implemented in the upcoming KDE Plasma 5.17 desktop environment is a totally revamped System Settings window, which now features a modern look and feel to make setting up various aspects of the KDE Plasma desktop a breeze for newcomers and advanced users alike. Apart from the modernized System Settings, KDE Plasma 5.17 will let users sort the order of image slideshow wallpapers, add a “Manual” mode to the Night Color feature so you can turn it on and off whenever you want, as well as support for syncing DPI and NumLock key status to the SDDM login screen. Other changes will include rewritten controls for widget positioning on the desktop to improve location of widgets and the ability for widget resize icons and handles to automatically increase their size on touchscreens , as well as new icons to the Plasma Discover package manager. Last but not least, the KDE Plasma 5.17 desktop environment promises a more user-friendly Audio Volume widget, will let users choose which category they want to use for the new Unsplash Wallpapers Picture of the Day plugin, and warn users when apps need to be restarted for new fonts are being applied. The final release of the KDE Plasma 5.17 desktop environment is expected to hit the streets later this fall on October 15th. It will be available for public beta testing starting September 19th. Under the hood, KDE Plasma 5.17 will be using the Qt 5.12 and 5.13 libraries, along with the KDE Frameworks 5.63 and KDE Applications 19.08 software suites.

DebConf20 Conference Takes Place August 23-29 for Debian GNU/Linux 11 “Bullseye” Next year, in 2020, the Debian Project will celebrate 12 years from the launch of the first DebConf Debian developer conference, and they selected Israel's Haifa instead of Portugal's Lisbon for DebConf20 despite Israel's political system. Now, they announced the official dates for DebConf20, which will take place between August 23rd and 29th. DebConf20 is for Debian GNU/Linux 11 “Bullseye,” the next major release of the famous Debian GNU/Linux operating system coming after the recently announced Debian GNU/Linux 10 “Buster” series. Therefore, all the discussions and workshops will be to share ideas and knowledge that will ultimate lead to new features to be implemented in Debian GNU/Linux 11 “Bullseye.” DebConf represents an important experience for the Debian developer, but also for users, who can gather together to share their knowledge and laid down the plans for the next major release of the Debian GNU/Linux operating system. For more information about DebConf20, check out the official website at https://wiki.debian.org/DebConf/20. Work on the upcoming Debian GNU/Linux 11 “Bullseye” operating system series already started, as developers were recently invited to upload their packages to the Debian Testing repositories, where the development takes place. However, it will be a couple of years until Debian GNU/Linux 11 “Bullseye” will see the light of day, most probably in the summer of 2021.

Canonical Releases New Linux Kernel Live Patch for Ubuntu 18.04 and 16.04 LTS Coming hot on the heels of the last Linux kernel security updates released by Canonical last week for all supported Ubuntu Linux releases, this new kernel live patch is now available for users of the Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating systems who use the Canonical Livepatch Service to apply rebootless kernel updates. It fixes five security issues, including a race condition (CVE-2019-11815), which could lead to a use-after-free, in Linux kernel's RDS (Reliable Datagram Sockets) protocol implementation that may allow a local attacker to crash the system or execute arbitrary code, as well as a flaw (CVE-2019-2054) affecting ARM CPUs, which lets local attackers to bypass seccomp restrictions. Also patched are two issues (CVE-2019-11833 and CVE-2019-11884) discovered in Linux kernel's EXT4 file system and Bluetooth Human Interface Device Protocol (HIDP) implementations, which could allow a local attacker to expose sensitive information (kernel memory) as the Linux kernel failed to properly zero out memory or verify NULL terminated strings in certain situations. Additionally, the kernel live patch includes a fix for an eight-years-old exploit (CVE-2011-1079) discovered by Vasiliy Kulikov in Linux kernel's Bluetooth stack, which could allow a local attacker to crash the system, which could lead to a denial of service or the leak of contents of kernel stack memory, putting the privacy of users at risk. All users of the Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating system series using the Canonical Livepatch Service can now apply the rebootless kernel live patch on their installations. The version of the kernel liv patch that needs to installed is 53.1 for both generic and lowlatency flavors.

Canonical Announces Amazon EC2 On-Demand Hibernation for Ubuntu 18.04 LTS As one can imagine, the Amazon EC2 On-Demand Hibernation functionality lets users start up Amazon EC2 instances, configure them to their needs, hibernate them, and then launch them again whenever they want with all the running apps in the last state before they were put to sleep. With Amazon EC2 On-Demand Hibernation there's no need to rebuild the memory footprint of your apps, and it also lets you maintain a fleet of pre-warmed Amazon EC2 instances that may increase your productivity without the need to modify any of your existing applications in the cloud. If you're using Ubuntu on AWS (Amazon Web Services), you can now benefit of Amazon EC2 On-Demand Hibernation in Ubuntu 18.04 LTS (Bionic Beaver). To enable it, you need to use the necessary software updates in the Ubuntu 18.04 LTS AWS Machine Images (AMIs) with a serial of 20190722.1 or later. Before using Amazon EC2 On-Demand Hibernation, users should keep in mind of a known issues related to KASLR (Kernel Address Space Layout Randomisation), which may prevent KASLR-enabled machines to not resume completely after hibernation. As a workaround, Canonical recommends users disabling KASLR. According to Canonical, Amazon EC2 On-Demand Hibernation will soon be available for other supported Ubuntu releases on AWS (Amazon Web Services), such as Ubuntu 16.04 LTS (Xenial Xerus) or newer releases like Ubuntu 19.04 (Disco Dingo). However, the company did not said when these Ubuntu releases will be updated.

Linux Kernel 5.1 Reached End of Life, Users Urged to Upgrade to Kernel 5.2 Announced in early May 2019, the Linux 5.1 kernel series brought the ability to use persistent memory as RAM, as well as support for booting to a device-mapper device without using initramfs, support for cumulative patches in live kernel patching, and more preparations for year 2038. The Linux 5.1 kernel has now reached end of life with the 5.1.21 maintenance update released by Greg Kroah-Hartman earlier this week. If you are still using the Linux 5.1 kernel on your favorite GNU/Linux distribution, you should either update it as soon as possible to the latest Linux kernel 5.1.21 point release, or upgrade it to the Linux 5.2 kernel series, the latest version of the moment of writing being Linux kernel 5.2.5.

The VR Linux desktop is on its way Virtual reality (VR) is moving from games to work, but on the Linux desktop it's had a hard row to hoe. While many VR peripherals and head-mounted display (HMD) support Linux, some “supported” games have trouble running on Linux. VR gaming on Linux is getting better. But if you wanted to use a Linux desktop via VR, you were out of luck. Your luck may be turning now with the xrdesktop. Xrdesktop is an open-source project. It's designed to let you work with traditional desktop environments, such as GNOME and KDE, in VR. It does this by making window managers aware of VR. It then uses VR runtimes to render desktop windows in 3D space. Once there, you'll be able to work on the desktop using VR controllers in place of a mouse and keyboard. Want to give it a whirl? You can find installation instructions on xrdesktop Wiki. The program is available in packages for Arch Linux and Ubuntu Linux. You can also install it on other distributions, but you'll need to install xrdesktop from source. Source: https://www.zdnet.com/article/the-vr-linux-desktop-is-on-its-way/
KDE And GNOME Are Joining Hands To Build A New-Age Linux Desktop There are many Linux users out there and despite that, Linux desktops have failed to break into the mainstream when compared to Microsoft’s Windows. One of the main reasons behind it, as described by Linus Torvalds, is “the fragmentation of different [Linux] vendors.” There are multiple Linux vendors, unlike the Windows ecosystem, which creates a lack of a unified approach. However, now two of the most popular Linux desktop competitors – GNOME Foundation and KDE – are coming together to work on a Linux desktop. Both open-source biggies are set to sponsor the Linux App Summit (LAS) 2019 which is scheduled for November 12th and 15th, 2019. The statements issued by GNOME and KDE ahead of the event indicate that this time, we could see some concrete decisions regarding the future of Linux operating systems. By working together, they want to bring a unified approach to the Linux community and look past the variety of distros. The aim is to come up with a unified application system that is scalable.

Canonical Releases Linux 5.0 Kernel (HWE) Security Update for Ubuntu 18.04.2 LTS This Linux Hardware Enablement (HWE) kernel from Ubuntu 19.04 for Ubuntu 18.04.2 LTS includes the same fixes for four security flaws that Canonical added in the lastest kernel for Ubuntu 19.04 last week, including an integer overflow (CVE-2019-11487) discovered in Linux kernel, which could lead to use-after-free issues as local attackers were able to use the exploit to execute arbitrary code or cause a denial of service (system crash). Additionally, the security patch addresses a race condition (CVE-2019-11599) discovered by Google Project Zero's Jann Horn in Linux kernel when performing core dumps, which could allow a local attacker to expose sensitive information or crash the system by causing a denial of service (DoS attack). Also fixed are two issues (CVE-2019-11833 and CVE-2019-11884) discovered in Linux kernel's EXT4 file system implementation and Bluetooth Human Interface Device Protocol (HIDP) implementation, both of each could allow a local attacker to expose sensitive information (kernel memory).
