Will antivirus be more significant on Linux desktop after this xz-util backdoor?

I understand that no Operating System is 100% safe. Although this backdoor is likely only affects certain Linux desktop users, particularly those running unstable Debian or testing builds of Fedora (like versions 40 or 41), **Could this be a sign that antivirus software should be more widely used on Linux desktops? ** ( I know...

Ramen_LadyHKG,

Real exploiters go bug hunting for zero days. The XZ thing was a humorous clown dancing a jig in a minefield. The clown spent 5 years on the sideline, then stepped on a mine immediately upon entry.

I like your last statement.

I agree that users should take responsibility for their system, I myself learned to fully encrypt my Linux with luks2 and things about secure boot, tpm2 or so.

That’s why I’m making assumption of the need for non-tech savvy users, like most Windows users if they come to Linux world.

I cannot get Turbo Boost working on Linux for my Intel Kaby Lake R processor (i7-8650u), always below 10W, 2.1GHz. Current throttling. #Surface #Laptop (www.techpowerup.com)

It’s a laptop from Microsoft, Surface Book 2. I run Fedora Linux and Arch Linux, both of them have this issue. Either vanilla kernel or surface kernel has the same problem....

Ramen_LadyHKG,

opped working, and I couldn’t make it permanent. I would think you’d have to understand a bit of kernel development to be able to mitigate this is

Thank you for your share! I’ve seen those links before, no luck.

I think modifying MSR is what this script does. Throttled / Erpalma - Github

Ramen_LadyHKG,

Certain laptop CPUs are not adequately supported on linux.

This is really sad. I found almost all **Intel Kaby Lake R ** processor suffer this problem.

Last night, I run pacman -Syu update and let it run overnight.

it failed when I woke up, I didn’t notice it and restart for newer kernel. Then the WM (sddm) fxxked up. I try to reboot it into mutli-user mode and reinstall kde plasma. it shows bunch of corrupted libraries errors LOL.

I took some time on internet looking for solution, finally found one. Reinstall all dependencies + pacman update cache in ram. https://www.reddit.com/…/recover_system_from_crash…/

pacman -Qqdn > pkglist_deps.txt

pacman --asdeps -S $(< pkglist_deps.txt)


pacman --cachedir /tmp/pacmancache -Syu

Ramen_LadyHKG,

Error I got libxxx.so is not an ELF file xxxxx file is already exist, cannot process the update

Ramen_LadyHKG,

I need to find a way to let pacman check free space before update as for now, I will use /tmp as cache

Ramen_LadyHKG,

Wish they didn’t discontinue Surface Book series

Ramen_LadyHKG,

If I can switch tty to get a terminal, I can kill the process myself. But you can’t.

Ramen_LadyHKG,

In the case of laptops with integtrated graphics + nvidia graphics (soldered) (so called “optimus laptops”),

my case is In the case of laptops with integtrated graphics + nvidia graphics (soldered) (so called “optimus laptops”)

I thought optimus laptops is old kind of laptop. Newer laptop, like mine (Surface Book 2) use another thing call Prime offload might be same thing? IDK

when I want to run apps with nvidia gpu, I will have to use environment variables, ex __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia osu
