Vložíl som CD nabótoval rozdelil disk nakofiguroval nainštaloval a reebot. A ide. Dokonca aj acpi.

Hybernácia nie je bohvie čo ale to asi tým kernelom. Modem tiež som nerozchodil i keď sa nahral modul slamr(ovladač) ale proste to nešlo.(láma).Všetko ostatné detekovalo.

Unknown: Ale nenahrá modul speedstep centrino. Pozeral som sa na číslovanie procesora v zásade by malo fungovať menenie frekvencie ale nefunguje.
AraxoN: Menenie frekvencie funguje cez modul p4-clockmod, ale efekt na výdrž baterky je zanedbateľný.
Valoun: Osobně mi nastavení frekvence uvedené níže ušetří 30-45 minut baterky.
l_n: Při instalaci Debian Sarge 3.1 r0a z DVD se objeví problém v okamžiku, kdy systém poprvé bootuje z harddisku (druhá fáze instalace). Během natahování modulů to zamrzne. Řešení je nainstalovat základní systém Debianu z DVD (CD), potom místo spuštění z harddisku, ke kterému installer vyzve, nejdřív nahradit defaultní jádro vlastním. Moduly pro usb (uhci, ehci) a další potřebné jsem zakompiloval přímo do jádra. Potom už vše proběhlo v pohodě. Bohužel nevím, který modul to přesně způsoboval.
Pozor, nezapomenout vyměnit i moduly v /lib/modules/...

---

Pouzil jsem distr.Gentoo, jadro 2.6.10. (patrne minimalni verze jadra pro sleep/hibernate)

• Touchpad: synaptics driver (Gentoo: x11-misc/synaptics-0.14.0) funguje i bezny PS/2 ale ten uvedeny umi i rolovaci prouzek (fukce kolecka).
• Eth: RealTek RTL-8139, modul 8139too - OK
• Zvuk: Intel/SiS/nVidia/AMD/ALi AC97, modul snd_intel8x0 - OK
• sleep/hibernace:
  1. jadro >=2.6.10,
  2. patch software-suspend-2.1.7-for-2.6.10 (http://www.suspend2.net/)
  3. konfigurace:
        <*> Software Suspend 2
        <*> Swap Writer
        <*> LZF image compression
        <*> Text mode console support
        () Default resume device name (vyplnit dev swap oddilu)
        ACPI: vybrat skoro vse, ale urcite:
        [*] Sleep States
  4. balicek sys-apps/hibernate-script
  5. balicek vbetool-0.2 (nutny pro obnovu gr.modu po sleep/resume)
  6. /etc/hibernate/hibernate.conf: (jen to co je asi dulezite:)
        UseSwsusp2 yes
        Reboot no
        PowerdownMethod 5
        SwitchToTextMode yes
     
  7. /etc/hibernate/sleep.conf: (-"-)
        UseACPISleep 3
        UnloadModules snd-intel8x0
        EnableVbetool yes
     
  8. LILO: 2 kopie boot sekce s ruznym append:
     Pro resume po hibernaci:
        label = "Resume"
        append = "resume2=swap:/dev/hda3"
     Pro normalni boot:
        label = "Boot"
        append = "noresume2"
     Pozor! resume musi probihat pod stejnym jadrem jako bylo pri hibernaci
     
  9. jak to spustit:
        hibernace: /usr/sbin/hibernate
        sleep mode: /usr/sbin/hibernate-sleep

Pozor! veci okolo sleep/hibernate jsem certve rozchodil. Casem napisu jaka je procentni uspesnost probouzeni ;)
UPDATE po 2 mesicich intenzivniho pouzivani:
   sleep: 100% uspesnost
   hibernate: odhaduji ~98% uspesnost - jednou se stroj neprobudil vubec a asi 3x jsem laboroval s xscreensaverem (nechtel uvolnit Xwin, nejak to souvisi se zvukovymi moduly)
UPDATE po 1/2 roce: temer 100% uspesnost, problemy pouze vyjimecne.
Co mi nefunguje:

• ACPI nedetekuje ventilator => neumim ho zatim ovladat, spousti se automaticky (ale dava informace o 'thermal zone' - mozna to souvisi).
• Modem - je to pry typ 'conexant', ovladace dostupne na http://www.linuxant.com/, jsou zdarma jen omezene na 14.4kbps bez faxu, plna licence za asi 15$. Podarilo se mi vytocit, jsou slyset pokusy o navazani spojeni, ale nespojil se ani jednou :(
  Chodi to nekomu?

Co zde jeste take funguje:

• Informace o pripojeni ACpower, teplote (?CPU) a stavu baterky dava ACPI v dostatecne mire.
• PCMCIA WiFi ZCOM XI-330 s hostap-driver zde jede vcetne hotplug. (S jadrem 2.4.x fungoval i modul wlan-ng, ale s 2.6.x se mi ho nepodarilo prelozit.)
• S jadrem 2.6.x funguje vypinani touchpadu (tlacitko nad nim), s 2.4.x se nevypinal.
• UPDATE: PCMCIA modem (nejaky noname), prida virtualni seriovy port, pripojeni do internetu bez problemu.
• GPRS pripojeni pres pppd a Siemens MT50 pomoci serioveho kabelu a prevodniku USB2serial (chip pl2302, prida /dev/ttyUSB0)
• UPDATE: Mp3 prehravac v USB klicence znacky Tchibo :)
  (fakt: oni rozjeli i prodej vsechno mozneho)
  je to usb-storage kompatibilni disk/prehravac/diktafon.
