P.S.- mislio sam da želis virtualku složit da ti se automatski baca u fullscreenu u određenu rezu (ali da je i dalje fleksiblno). Dali ti se na taj način skalira virtualka?

Probati ću. Uf to je za Gnom, ja vozim KDE.
Da htio sam da mi automatski odabere rezoluciju. U virt manageru to ne uspijevam ali kad u guestVM conf file u x11 ili malo editiram grub za wayland, sve nakon logina je u QHD rezoluciji. Prije nisam imao izbora za moju rezoluciju, imao sam ili veću ili manju ali ne i moju. Nije mi jasno zašto virt.manager nema 2560x1440(16:9) bar to nije neka divlja rezolucija

On this day 34 years ago, an unknown computer science student from Finland announced that a new free operating system project was “starting to get ready.” Linus Benedict Torvalds elaborated by explaining that the OS was “just a hobby, [it] won’t be big and professional like GNU.” Of course, this was the first public outing for the colossal collaborative project that is now known as Linux.

Happy 34th birthday Linux! from r/linux

Na kraju srusio fedoru kde i zavrsio na cinnamonu.

Kde je bio osjetno sporiji dok je laptop bio na bateriji na balanced profilu. Sa cinnamonom nema taj delay.

Odusevljen sam kako lagano radi i sta se sve moze nakalemit gore preko appleta koji su vrh 🙂. Probao sam i xfce preko live usb-a al bas je nekako zastario u usporedbi sa cinnamonom tako da sam odustao od njega.

Mislim da se na kraju sve svodi na graficke drivere. Sa AMD-om i Intelom nisam iskusio nikakvih problema, dapace, nema vise Screen-Tearing efekta koji me godinama na Desktop Linuxu pratio. Nvidia je po tom pitanju jos uvijek jako traljava, katkad i nestabilna.

Da, samo što nvidia ima 90% GPU marketsharea :kafa: I 90% korisnika će imati probleme sa Waylandom. Možemo mi upirati prstom u nvidiu ali end-usere nije briga tko je kriv.

Nvidia i ozbiljan Linux korisnik ne idu u istu rečenicu. AMD je odavno sredio priču s open source Linux driverima. Pa, ako mogu oni, mogu i drugi.

Kolega je u pravu. Kvaka je da nvidia jednostavno ne radi najbolje sa Waylandom - zasad. Al ovaj gore link ima samo djelomicno veze sa nouveau driverima ;) Nvidia je pocela raditi na sluzbenom open-source kernel driveru kakav ima i AMD. Userspace dio ce ostati i dalje zakljucan. Kolko mi je poznato nouveau je cisto "community driven" bio dosad (ispravite me ako grijesim). Prve verzije su vec u Fedori (akmod-nvidia-open,nvidia-open* paketi). Nisam isprobao pa nemogu komentirati jel su ok ili nisu.

Linus Torvalds updated the kernel's MAINTAINERS file to mark Bcachefs as "externally maintained," signaling he won't accept new Bcachefs pull requests for now. "MAINTAINERS: mark bcachefs externally maintained," wrote Torvalds with the patch. "As per many long discussion threads, public and private."

"The Bcachefs code is still present in the mainline Linux kernel likely to prevent users from having any immediate fall-out in Bcachefs file-systems they may already be using, but it doesn't look like Linus Torvalds will be honoring any new Bcachefs pull requests in the near future," adds Phoronix's Michael Larabel.

For those using the upstream open-source NVIDIA Linux driver "Nouveau", with a pending fix coming for Linux 6.17 and existing kernel releases it should be a much more stable and reliable experience.

Instability issues have been somewhat common for the Nouveau driver usage but up until recently were hard to track down and reproduce. Fortunately, thanks to the stellar work of Faith Ekstrand and David Airlie, they managed to now address this in large part. Faith Ekstrand explained it's been a fencing bug where the context would randomly wedge and could lead to the app/game freezing and losing your X.Org Server / compositor in the process. After many bug reports over the past year, a fix is on the way.

Prije par godina napravljen je flash Coreboot-a na Thinkpad W530 (Ivy Bridge). Linux je radio kako treba, ali se NetBSD zamrzavao kod povratka iz nekog deep statea, jer kernel ne podržava C6/C7 uopće IIRC (https://man.netbsd.org/acpicpu.4), uz to smo zaključili da se dešava kada CPU počne dizati clockove / voltažu. Vratili smo originalni BIOS jer stvari nisu funkcionirale.

Sada sam primjetio da je izašao patch https://review.coreboot.org/c/corebo...l_206ax_init.c za navedeni problem; https://ticket.coreboot.org/issues/121

Novu verziju Coreboot-a u koju je gore navedeni patch ubačen još nisam testirao, ali po ovome što ljudi pišu, sa Linuxom bi trebao raditi bez "intel_idle.max_cstate" koji je trošio više struje i laptop je bio konstantno bučan, pa zaključujem da bi problem mogao biti riješen i na NetBSD-u obzirom da Coreboot i eventualno Intel microcodovi imaju svoj utjecaj. Mišljenje prije pokušaja?

U intel_idle.c driveru imamo; za C3 59µs, za C6 80µs, za C7 87µs, dok Coreboot patch koristi za C3 60.4µs, za C6 81µs i za C7 89.1µs, prethodno bez patcha C3 81.9µs, za C6 106.5µs i za C7 111.6µs.

Referenca https://raw.githubusercontent.com/to...e/intel_idle.c

    .state_table = ivb_cstates,

    .disable_promotion_to_c1e = true,

};



static struct cpuidle_state ivb_cstates[] __initdata = {

    {

        .name = "C1",

        .desc = "MWAIT 0x00",

        .flags = MWAIT2flg(0x00),

        .exit_latency = 1,

        .target_residency = 1,

        .name = "C7",

        .desc = "MWAIT 0x30",

        .flags = MWAIT2flg(0x30) | CPUIDLE_FLAG_TLB_FLUSHED,

        .exit_latency = 87,

        .enter = &intel_idle,

        .enter_s2idle = intel_idle_s2idle, },

    {

        .enter = NULL }

};

Pretpostavljam da je Coreboot preuzeo IRTL vrijednosti iz Linux kernel Intel idle drivera, jer u specifikaciji ispod ih ne mogu pronaći. Gdje ih je Intel pronašao? (Tražio sam ih po internetu pola sata)

A new set of Linux kernel patches posted today work to improve the nested VMX performance for benefiting Intel processors making use of KVM virtualization.

Amazon engineer Fred Griffoul posted a set of five patches aiming to address performance issues around nested VMX (Intel) when handling unmanaged guest memory. In particular, memory passed via the "mem=" parameter or guest_memfd for non-confidential computing virtual machines.

It was found that with the current Intel VMX code there is significant performance overhead due to expensive remapping operations. With nested VMX usage the system is accessing guest pages during L2 VM entry/exit cycles leading to much overhead.

The XFS filesystem is advancing with online checking (xfs_scrub) set to become default in Linux 6.13, enabling metadata repairs without downtime after years of refinement. This boosts reliability for enterprises, complements features like v5 format and inode management, and aligns with growing data demands. Challenges include compatibility and user education.

The latest release candidate for Linux is out, but before its release, Linus Torvalds had something he wanted to get off his chest in his usual style.
"Stop this garbage already. Stop adding pointless Link arguments that waste people's time," he wrote on the Linux kernel mailing list.
"Add the link if it has *ADDITIONAL* information. Dammit, I really hate those pointless links. I love seeing *useful* links, but 99 percent of the links I actually see just point to stupid useless garbage, and it *ONLY* wastes my time. AGAIN."

The Linux Mint team have announced the release of Linux Mint 22.2 "Zara", an Ubuntu-based version which will receive updates through to 2029. The 22.2 release includes several new features, including new full screen options for the Hypnotix IPTV player, a version of the libAdwaita library to support themes, and artwork improvements. One of the big features is a fingerprint manager to providing authentication on computers which have a supported fingerprint reader. "Linux Mint 22.2 features a brand new XApp called Fingwit. This application is dedicated to fingerprint authentication. Fingwit detects if your computer has a fingerprint reader and lets you record your fingerprints. It then configures your system to use fingerprint authentication for: The screensaver, sudo commands, admin apps (pkexec). Note: If like most users you use home directory encryption or a keyring, the login screen still requires you to type a password. If you don't, you can configure Fingwit to also use fingerprint authentication in the login screen." Additional details are available in the project's what's new document.

ma nije problem manul copy. problem je sto evo traje oko 20-30 min po masini na taj microSD. 20-30mb/s ha ha. al dobro je sto ne radim snapshote pa sve skupa ne prelazi 28gb po masini.neznam dal microSD odlazi i od samog stajanja u masini (zagrijavanje?) ili ga drobi u pravilu samo "write", jer on je skoro pa nekoristen pa ak ga toplina ne shebava bude trajao "zauvjek":D pa je dobar za backup tak da je unutar laptopa sve (lenovo x280).

veci problem je sto izgleda da mi throttlestop postavke (UV, UC) "nisu bas rock solid" i zato lap krkne kad mu pokrenem vise Virtualki, sto jako rjetko radim.

back to that :fiju:...
