    Instalace archlinuxu na starší PC

    13.7. 21:07 | Přečteno: 1685× | poslední úprava: 13.7. 21:07

    Čas od času se v diskuzích objevujou dotazy jak a jestli je vůbec linux použitelný na starším hardware. Nedávno jsem tak probíral svoje domácí uložiště elektroodpadu a našel jsem tam starší německý desktop z roku 2006. Fujitsu Siemens ESPRIMO P2501 Ten počítač byl low-end už v době svojeho vzniku, dneska by udělal dojem možná tak na nějakého nadšence do archeológie. Originální Windows XP odmítaly naběhnout a přes všecky moje snahy v nouzovém režimu, zarputile končily v aktivační smyčce. Instalovat na to nějaké 15 let staré 32bit distro by nebyla ta správná zábava konečně ten Celeron už umí 64bit SSE2 SSE3 tak jsem si řekl, že když už používám archlinux, zkusím ho tak z hecu nacpat na stařečka taky.

    Instalaci zkusím popsat trochu víc podrobně krok za krokem, tak jak probíhala. Používám šifrování disku plus pár dalších drobností jako bootloader syslinux atd. Instalační USB fleška co tu mám je z letošního března, navíc arch si běhěm instalace stejně všecko stahuje online z netu takže by systém měl být aktuální hned.

    Na začátku v ůvodním menu, bylo potřeba zmáčnout TAB a doplnit jádru video=800x600. Když se to neudělá, naběhne framebuffer v maximálním rozlišení co monitor umí a na čtení toho titěrného písma je potom potřeba mikroskop. Přemazání starého disku:
    pv /dev/urandom > /dev/sda
    To zabralo asi 15-20 minut. 80GB není tak moc. Fdiskem jsem udělal novou tabulku a v ní dva oddíly. První sda1 FAT32 který bude jako /boot a zbytek sda2 jako /.
    fdisk -l /dev/sda
    Disk /dev/sda: 74.53 GiB, 80026361856 bytes, 156301488 sectors
    Disk model: WDC WD800JD-55MU
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disklabel type: dos
    Disk identifier: 0xb8fc9564
    
    Device     Boot   Start       End   Sectors  Size Id Type
    /dev/sda1  *       2048   2099199   2097152    1G  c W95 FAT32 (LBA)
    /dev/sda2       2099200 156301487 154202288 73.5G 83 Linux
    
    Pro /boot by klidně stačilo 100MB ale nechal jsem rači víc, kdyby bylo potřeba v budoucnu na nějaké experimenty. Dál jsem nastavil šifrování systémového disku:
    cryptsetup -v -y luksFormat /dev/sda2
    cryptsetup open /dev/sda2 sysdisk
    Vytvoření a mount filesystémů:
    mkfs.ext4 /dev/mapper/sysdisk
    mount /dev/mapper/sysdisk /mnt
    mkfs.fat -F32 /dev/sda1
    mkdir /mnt/boot
    mount /dev/sda1 /mnt/boot
    Doteď to byla jenom taková předehra. Ta opravdová instalace začíná až teď. Stáhnem z internetu nějaký ten základ:
    pacstrap /mnt base base-devel linux linux-firmware mtools syslinux man-db vim dhcpcd openssh ntp
    Vygenerujem nový/etc/fstab:
    genfstab -U /mnt >> /mnt/etc/fstab
    Jako bootloader jsem chtěl syslinux. Archlinux má pro tápajícího uživatele předchystaný pomocný skript syslinux-install_update který nakopíruje všecko potřebné do /boot, automaticky pomocí dd nakopíruje MBR na správné místo, nastaví na oddíl boot flag atd. S ním je instalace zavaděče brnkačka:
    syslinux-install_update -i -a -m -c /mnt
    Po tomto kroku se musí upravit konfigurák syslinuxu /mnt/boot/syslinux/syslinux.cfg aby nám to po restartu naběhlo tak jak chceme:
    APPEND root=/dev/mapper/sysdisk cryptdevice=/dev/sda2:sysdisk rw video=800x600 net.ifnames=0 audit=0 mitigations=off
    Tady jsem se přepnul pomocí chroot na nový systém:
    arch-chroot /mnt
    Pár základních nastavení. Čas, locales, hostname:
    ln -sf /usr/share/zoneinfo/UTC /etc/localtime
    vim /etc/locale.gen
    locale-gen
    echo LANG=en_GB.UTF-8 > /etc/locale.conf
    echo nuna > /etc/hostname
    Teď bylo potřeba vygenerovat nový kernel image, jinak by to po restartu nenašlo náš šifrovaný disk. Do souboru /etc/mkinitcpio.conf se musí přidat hook encrypt:
    HOOKS="base udev autodetect encrypt modconf block filesystems keyboard fsck"
    A potom spustit:
    mkinitcpio -p linux
    Tady je vhodné nastavit rootovi nějaké heslo.
    passwd
    Já jsem na toto v návalu emocí zapomněl a po restartu mě čekalo překvapení. Systém sice krásně naběhnul, ale nešlo lognout. Ještě že resetovat heslo rootovi na linuxu je tak snadné :-) Po restartu se muselo udělat pár úprav, aby se to trochu dalo používat. Jeden giga paměti je pro desktop už docela na hraně tak trocha swapu může pomoct:
    pv -Ss 2g /dev/urandom > /swapfile
    chmod 600 /swapfile
    mkswap -U clear /swapfile
    swapon /swapfile
    Je fajn mít swap přímo v /etc/fstab aby se aktivoval automaticky:
    /swapfile     none    swap    defaults        0 0
    Vypnout coredumpy v souboru /etc/security/limits.conf:
    *       hard    core    0
    Nastavit trošku lidské doplňování tabulátorem v shellu:
    # /etc/inputrc
    TAB: menu-complete
    "\e[Z": menu-complete-backward
    Vytvoříme obyčejného uživatele, umožníme mu používat sudo a nastavíme mu autologin aby nemusel zadávat heslo dvakrát (jednou k disku a podruhé k lokálnímu ůčtu). Je toho víc ale abych tu neopisoval půlku archwiki toto musí prozačátek stačit. Takto nainstalovaný systém sežere přibližně 90MB paměti. To mi nepřijde jako nějaká extra hrůza na to že máme rok 2022, běží nám tam systemd, funguje nám síť a bash ... Trošku jsem měl obavy jestli to šifrování disku nebude brzdit processor no ukázalo se, že docela stíhá. Defaultně se používá aes-xts:

    Šifrování je dneska už nutnost. Nechceme přece aby se nám v datech hrabala každá opice, která dokáže použít příkaz mount. Nešifrovaný /boot na domácím pc zas tak moc nevadí pokud nám v baráku neřádí nějaká zlá pokojská.

    Protože se to má používat jako desktop, slušelo by se doinstalovat xorg, pár nějakých fontů, webový prohlížeč, něco na multimédia atd. Jako správce oken používám icewm v nastavení kdy vypadá dost podobně jak windows95. Trochu pokročilejší správce schránky clipit, zámek obrazovky xtrlock, na video/zvuk mpv na obrázky někdy mpv někdy pix(když chcu náhledy). Text edituju střídavě ve vimu nebo geany, podle nálady. Celkový dojem ještě umocňuje Chicago95. Přehledný, hranatý šedomodrý svět bez rušivých módních výstřelků, tak to mám rád. S tímto už jsme po asi 40ti sekundách od startu počítače na zhruba 140MB obsazené RAM v grafickém režimu. Taky se vyskytl drobný zádrhel s 3D akcelerací. Nějaký horlivý pokrokový revolucionář vyhodil z mesa 22 podporu pro starší intel grafiky. Naštěstí existuje balíček mesa-amber, glxgears teď dává místo původních 200 asi 680fps. Přehrávání h264 videa velikosti 720p přehrávačem mpv žere tak plusmínus 65% výkonu CPU(záleží na bitrate). S 1080p už je to horší. Ve scénách kde se obraz hýbe málo se to ještě jakžtakž dá, ale jak přijde nějaká akčnější scéna nebo nedejbože začne třeba pršet, obraz se začne škubat.

    Na web jsem už zkoušel ledaco, ale od té doby co umřela stará opera12 jenom skřípu zubama. Jako nejmenší zlo mi v současné neutěšené době přijde trochu potuněný firefox-esr asi. Mimochodem pamatujete se ješte na ten hype přibližně dvacet let zpátky? "Nahraďte svůj beznadějně zastaralý, pomalý fujky fuj internet explorer naším rychlým moderním ůžasným firefoxem!". Chrome zákeřně přibalený ke každému instalačnímu balíčku pro windows. Stačilo trošku nedávat pozor při instalaci libovolného setup.exe, odklikávat default volby a už to měls nasáčkované v počítači jak virus(nevím jak se říká softwaru nainstalovanému z nepozornosti). My co jsme tenkrát používali operu, jsme se jenom uculovali. Tehdá jsme netušili jaké inferno nás čeká za dvacet let.

    Okamžik pravdy aneb youtube v prohlížeči a hry

    Trochu překvapivě není úzkým hrdlem pro prohlížení webu málo RAM, ale pomalý CPU. ublock a defaultně vypnutý javaskript jsou nutnost. Nesmí se otevřít víc jak 4-5 tabů nebo to začne divoce swapovat. Na prohlížení webů jak je třeba abclinuxu to ale stačí v pohodě. Načtení webu youtube firefoxem trvá dýl jak boot celého počítače, (zkoušel jsem i prohlížeč vivaldi ale bylo to snad ještě lenivější jak firefox) no odměna za trpělivost nebyla nakonec tak hořká. 480p video při vytížení CPU na 100% bylo jakžtakž dívatelné. Z her jsem zkoušel jenom pár starých kousků v dosboxu a moje oblíbené Diablo2 Eastern Sun na tom ve wine taky lítá jak z praku. Něco novějšího jsem ani neměl chuť a odvahu zkoušet.

    Takže když se chce jde to. Né že né. I když to občas trošku drhne kvůli rozežranýmu webu.

Nějaké minimální zrychlení oproti třeba chrome tam vidět je, ale kdo si má pamatovat těch 250 klávesových zkratek? :-D Řekl bych, že větší vinu za obludnost dnešního webu mají lidi(nebo spíš boti) kteří ty weby generujou, než tvůrci web browserů. Ti se jenom snaží udržet krok.

    Na zobrazování dokumentace, vyhledání informací apod. používám na laptopu links -g – jednoduché klávesové zkratky, rychlý, ukazuje průběh načítání (užitečné zejména s připojením kvality semtambajt), bohužel pomalu vykresluje (ano, opravdu pomalu vykresluje) a podpora CSS (alespoň layout) by nebyla na škodu. Pro jiné věci Falkon (plánuji nainstalovat surf). Děkuji za tip na qutebrowser – to bude možná pohodlnější (?) než surf.

    Takže na Chicago95 nemusí být Xfce ale běží to v pohodě na iceWM? Když by se tam dalo alespoň male SSD tak by to mohlo být použitelně rychlé i při swapu? Dalo by se to samé nebo obdobné naklikat v manjaro? Osobně na šifrování kašlu na starých pomalých PC, resp pouzivan jen secure Ata když to umí SSD Jakože když má někdo přístup k PC tak stejně může i připojit do USB mezi klávesnici a PC nějaký keyloger kterého bych si nevšiml atd..

    Takže by se musel PC zabezpečit asi sofistikovaněji než heslem atd..

    Příloha:
    Ono je to trošku složitější. Icewm je jenom správce oken. Není to kompletní desktopové prostředí. Má svoje vlastní themes v /usr/share/icewm/themes ale ty nijak neovliňujou vzhled programu uvnitř okna. Icewm se stará jenom o vzhled a chování oken napovrchu(dekorace a ovládací tlačítek na rantlu oka). GTK themes co jsou nainstalované v systému v /usr/share/themes/ ho myslím vůbec nezajímají. Když si nainstaluješ chicago95 tak icewm bude vypadat furt stejně. a je jedno co máš třeba v ~/.config/gtk-3.0/settings.ini. Ale všecky ostatní gtk3 programy by měly ten konfigurák respektovat. Já tam mám například toto:
    [Settings]
    gtk-icon-theme-name = Chicago95
    gtk-theme-name = Chicago95
    gtk-font-name = Luxi Mono 10
    gtk-cursor-theme-name = Vanilla-DMZ
    gtk-cursor-theme-size = 32
    gtk-toolbar-style = GTK_TOOLBAR_BOTH_HORIZ
    gtk-toolbar-icon-size = GTK_ICON_SIZE_LARGE_TOOLBAR
    gtk-button-images = 1
    gtk-menu-images = 1
    gtk-enable-event-sounds = 0
    gtk-enable-input-feedback-sounds = 0
    gtk-xft-antialias = 0
    gtk-xft-hinting = 1
    gtk-xft-hintstyle = hintslight
    gtk-xft-rgba = rgb
    gtk-recent-files-enabled=true
    A roletkové menu v editoru geany vypadá jak obrázek v příloze.

    Ono to taky hodně naskáče, když to instalujes po skupinách. Jsem tam třeba instaloval base-devel to máš 24 balíků, xorg 48, xorg-apps 35, xorg-drivers 16. to máš celkem 123 balíků. pacman -Qe vypíše 160 celkem. Takže když to odečtu mi vychází 37 programů jsem doinstalovával ručně mimo skupiny. Plus závislosti ... to jsi na tisícovce ani nemrkneš.

    zdravim,

    tak pred rokem a pul jsem delal nejaky test, ze jsem nechal bezet jenom jedno jadro (nebo 4=NTB). Na konfiguraci s Celeronem a HDD to tedy nema.

    Toto asi hodne lidi zna:

    echo 0 > /sys/devices/system/cpu/cpuXXX/online

    Delat se na tom dalo, ale nic moc. Vcelku zajimavy test. Zkuste si nacist treba HTML stranku v prohlizeci/Youtube. Nebo start vyvojoveho prostedi.

    Pred 2 tydny jsem delal zajimavy test na masine. Vykon Tesseract 5 OCR asi 75k stranek za hodinu.

    Některé algoritmy mají implementaci v SIMD instrukcích. SIMD instrukce se provádí v FPU. A FPU je obvykle sdílená mezi jádry CPU. Takže když šifruješ ve více vláknech, tak se spíše přetahuješ o FPU a přeléváš cache mezi vlákny. Takže efektivně jednojádro je rychlejší. Zkus z jádra vyházet crypto moduly se SIMD instrukcemi a ponechat tam jen generické implementace. Výkon by se měl srovnat.

    Celeron, 32 bity, jednojádro, před pár lety jsem ho v elektroodpadu upgradoval na 2.53 GHz. Tamtéž jsem upradoval RAM na 3 GiB i zdroj, desku jsem kdysi dostal, protože ten šrot už na Widle 7 nestačil, skříň se mi tu válela roky a použil jsem jí, protože má teploměr na procesor. Harddisk jsem koupil nový osmiterový, přece jen mám těch dat docela dost.

    Systém je aktuální Raspberry Pi Desktop, aby se mi to nepletlo s Malinou, filmy to zvládá ve fullscreenu na 720p, YouTube v Chromiu jede na 480p jakžtakž koukatelně, akorát před časem se mi zdálo že ten prohlížeč nějak zpomaluje, ale po pozavírání 600+ tabů se to vrátilo do normálu. Stránky se teda načítají trochu déle, ty tuny javascriptových sraček to holt přežvykuje pomalu.

    Už na tom jedu asi sedm let, od doby co mi chcípla stará deska s kondenzátory nafouknutými jak balony, a na běžné každodenní používání to pořád stačí, kompilovat vlastní kernel nemám v plánu. Ale RPi 400 s dvaatřicetibitovým systémem je znatelně výkonnější :-D
