Cyberus Develops Open-Source KVM Backend For VirtualBox (www.phoronix.com)

Making use of Linux’s Kernel-based Virtual Machine (KVM) opens up new possibilities while users can still enjoy the VirtualBox VMM itself. The KVM support is part of the mainline kernel so there is less worries with not having to use the VirtualBox kernel driver, KVM tends to support new features quite quickly, and tends to be...

Known issues and limitations


<span style="color:#323232;">Currently, Intel x86_64 is the only supported host platform.
</span><span style="color:#323232;">    AMD will most likely work too but is considered experimental at the moment.
</span><span style="color:#323232;">Linux is required as a host operating system for building and running VirtualBox KVM.
</span><span style="color:#323232;">Starting with Intel Tiger Lake (11th Gen Core processors) or newer, split lock detection must be turned off in the host system. This can be achieved using the Linux kernel command line parameter split_lock_detect=off or using the split_lock_mitigate sysctl.

Docker can be run in rootless mode[1]. Ideally that should be the standard mode unless you have specific requirements not satisfied by rootless mode.

Use work laptop as personal device by dual booting on a separate internal drive?

I currently have a Dell laptop that runs Windows for work. I use an external SSD via the Thunderbolt port to boot Linux allowing me to use the laptop as a personal device on a completely separate drive. All I have to do is F12 at boot, then select boot from USB drive....

In most cases, work laptops have software(s) installed to automatically keep track of these activities, and flag it to security team of your organization. At that point, it will either lead to a formal warning to you, or termination/forced resignation.

From organization point of view, this is to avoid any accidental (or intentional) leak of confidential data, and/or accidentally (or intentionally) infecting your (work) system with malware/ransomware.

The latter had happened in one of my previous organizations, and the person responsible was terminated from job immediately.

Intel Thread Director Virtualization Patches Boost Some Workloads By ~14% (www.phoronix.com)

With this Intel Thread Director Virtualization to ensure the VM can properly manage task placement between P and E cores, the feature ended up yielding around 14% better performance than the status quo. That 14% win was with the 3DMark benchmark running on a Windows VM.

Are the latest generation (11th onwards) of Intel CPUs still affected by any of these two vulnerabilities?

I actually own a steam deck and I never had any major issues with it, so my only conclusion is that this time it’s the fault of either linux mint

Isn’t Steam Deck use AMD and not NVIDIA? Btw, playing CS:GO2 on Nvidia 3070 Ti on Linux desktop using driver version 545 doesn’t give me a major issue so far.

GNOME Sees Progress On Variable Refresh Rate Setting, Adding Battery Charge Control (www.phoronix.com)

As pointed out in This Week in GNOME, there’s been some continued work on Variable Rate Refresh for the GNOME desktop. The VRR setting within GNOME Settings continues to be iterated on as the developers iron out how they’d like to present the Variable Rate Refresh setting for users. The developers have been discussing how to...

Quality control is important for a project that is going to be supported for long time, and used by many. Slow but steady is a right approach for open source project, IMO.

I believe it’s actually a Mutter thing [1]

The application will stream the selected monitor if the mutter screencast portal is available. If it is unavailable, a fallback to X11 based frame grabbing will happen. As such, it should work fine in almost all setups.

If your use cases (a.k.a. requirements) are met by your current distro, never switch.

If you are satisfied with stability, availability of support, quick availability of security patches, never switch.

This is particularly important when you are using your Linux desktop as your daily driver.

Most you can do is to check what additional features other distros are offering (rolling release, hardened/zen kernel, x86-64-v2/3 support, file system type, user base, availability of packages, package formats, overall documentation etc.), validate if you really need those features.

If you are interested or just curious to test those features, install that distro on a VM (QEMU/KVM) to try it out first safely. Use it on VM for a while, make yourself comfortable with it. Once you are satisfied with it, only then switch.

Wayland-Proxy Load Balancer Helping Firefox Cope With Wayland Issues (www.phoronix.com)

Among the Firefox Wayland bugs, one of the top crash bugs is over a lost connection to a Wayland compositor. For dealing with it is to have a proxy between Firefox and the Wayland compositor to cache messages and prevent compositor message queue overflows.
