Dotaz: zavedenie modulu po prebudeni PC

[jany2]

Zdravim,

mam mensi problem. V PC mam DVB kartu, ktorej modul (lsmod) sa vola mantis. Donedavna som pouzival mint 17. V minte sme to riesili tuna a fungovalo to vynikajuco.

Teraz som vsak presiel z istych dovodov na debian 8 jessie 64bit a chcel som to vyriesit podobne. Cize som si doinstaloval pm-utils a v

/usr/lib/pm-utils/defaults

som editoval

#SUSPEND_MODULES=""

na

SUSPEND_MODULES="mantis"

Ale v debiane to vobec nefunguje. Skusil som to teda rucne odstranit a znova zaviest

rmmod mantis
modprobe mantis

a toto uz funguje dobre.

Ako by sa to dalo najjednoduchsie vyriesit, aby som nemusel vzdy po prebudeni odstranovat a zavadzat modul rucne.

thx

/etc/pm/sleep.d/foo:

#!/bin/bash

# Arguments can be:
# "suspend suspend"
# "resume suspend"
# "thaw hibernate"

case "$1" in
 "suspend")
  rmmod
 ;;
 "resume")
  modprobe

esac

chmod +x /etc/pm/sleep.d/foo

myslim ze to muze byt pro nej dost matouci, taky nechapu co moznejma argumentama chces rict :) takze rovnou pouzito se vsema moznejma, misto "rmmod" cistejsi "modprobe -r" a misto bash dostacujici sh ;)

#!/bin/sh

case $1 in
    suspend|suspend_hybrid|hibernate)
        modprobe -r mantis
        ;;
    # resume je probuzeni z suspend, thaw je probuzeni z hibernace
    resume|thaw)
        modprobe -r mantis
        ;;
esac

[nobody]

oprava: "modprobe -r" samozrejme jen pri odebirani ;)

#!/bin/sh

case $1 in
    suspend|suspend_hybrid|hibernate)
        modprobe -r mantis
        ;;
    # resume je probuzeni z suspend, thaw je probuzeni z hibernace
    resume|thaw)
        modprobe mantis
        ;;
esac

taky nechapu co moznejma argumentama chces rict :)

To je opsané z nějakého example konfiguráku i s komentářema. Co přesně dělá konkrétně to "suspend suspend" netuším, ty další dvě jsou probuzení a uspání do RAM a na disk.

[jany2]

Skusal som to nedavno podla toho, ale neslo to. Este sa s tym pohram :) thx

[nobody]

jak se to chova, kdyz uspis pocitac zavolanim "sudo pm-suspend" ?
co najdes po probuzeni v /var/log/pm-suspend.log ? (asi nic, kdyz systemd...)

i kdyz ono kvuli systemd nejspis nefunguji ani pm-suspend skripty a musis pouzit systemd hooks...
viz: https://wiki.archlinux.org/index.php/Power_management#Sleep_hooks

btw: nejedu debian8 ani systemd, takze varim z vody a vysledku hledani ;)

[jany2]

btw nobody v riadku 5 by malo byt rmmod. To nevadi, aj tak mi to nefunguje :(

Ked chcem uspat cez "sudo pm-suspend" tak vizualne monitor je black, ale po chvili je zase normalny a v /var/log/pm-suspend.log je

btw nobody v riadku 5 by malo byt rmmod

Ne, nemělo, píše, že modprobe -r je čistší (afaik protože řeší závislosti).

Zjevně to pm-suspendem nejde a GUI nebo jak to uspáváš to dělá nějak jinak.

[nobody]

u "modprobe -r mantis" znamena -r remove, tedy odebrat modul, je to obdoba "rmmod mantis", ale resi to zavislosti a odstranuje ty nadale nepouzivane... k modprobe -r nabada i primo man page pro rmmod ktere se i samo oznacuje za trivialni, naproti tomu modprobe se oznacuje jako inteligentni ;)
rmmod is a trivial program to remove a module (when module unloading support is provided) from the kernel. Most users will want to use modprobe(8) with the -r option instead.

nicmene pokud ti to chodi rucne s rmmod a chtel si ve skriptu rmmod, nemel si nechavat to -r, protoze pak ti hlasi v logu error a nic to neodebiralo... viz:
Running hook /etc/pm/sleep.d/foo suspend suspend:
rmmod: invalid option -- 'r'
/etc/pm/sleep.d/foo suspend suspend: Returned exit code 1.

podle logu se to snazilo uspat, ale neco se do toho vecpalo(nemyslim ze ten vadnej -r parametr, ale muzes to v tom foo opravit a zkusit pm-suspend znovu) a tak misto uspani se zaclo zas probouzet, viz:
So aug 22 18:10:57 CEST 2015: Inhibit found, will not perform suspend
So aug 22 18:10:57 CEST 2015: Running hooks for resume


kazdopadne, kdyz zkusis po te oprave a nahodou by to slo, jeste otazka co pouziva tve gui kde volis uspavani, nebo lid (zavreni vika), nejsnaze zjistis:
pouzijes gui a/nebo zavreni_vika a po probuzeni zkontrolujes pm-suspend.log jestli nic noveho => nepouziva se...
to co se pouziva pak mozna poznas podle logu, idealne si je seradit podle data a projit logy s casem uspavani/probouzeni...
nebo rovnou vyzkousej si prepsat "foo" do systemd hooks viz
nebo pockej az se ozve nekdo kdo ma Debian8 na zeleze :)

[jany2]

PC davam do usporneho rezimu (suspend to ram (polmesiacik na klavesnici)). Skusal som to aj s modprobe  -r aj s rmmod, ale nefunguje nic. Pises aby som si foo prepisal do systemd hook (nemam ponatia ako to urobit :) som obycajny uzivatel linuxu a mozno viem nejake zaklady a hlavne neviem dobre anglicky, takze mi je dost tazko cerpat z nejakych manualovych stranok).
Vyhladal som si nieco o systemd a vacsina s tym nie je spokojna a nadava na to (ze lepsi bol pre nich init). Ja som nemal ponatia co je to init, alebo systemd, teraz viem, ze sa stara o spravu sluzieb je spusteny ako prvy s PID 1.
No ak sa mi to nepodari vyriesit s vasou pomocou, tak mi ostane na krku spustat to rucne po prebudeni :(

[ekvivalent]

Zdravím ťa,

Vyzerá to tak, že o uspanie a zobudenie sytému sa stará systemd, je potrebné vytvoriť nasledujúce služby. V adresári /etc/systemd/system, si vytvoríš dva nasledujúce súbory:

sudo nano /etc/systemd/system/root-suspend.service, naplníš ho nasledujúcim obsahom:

[Unit]
Description=Local system suspend actions
Before=sleep.target

[Service]
Type=simple
ExecStart=-/usr/bin/modprobe -r mantis

[Install]
WantedBy=sleep.target

sudo nano /etc/systemd/system/root-resume.service, naplníš ho nasledujúcim obsahom:

[Unit]
Description=Local system resume actions
After=suspend.target

[Service]
Type=simple
ExecStart=-/usr/bin/modprobe mantis

[Install]
WantedBy=suspend.target

Následne povolíš tieto 2 služby:
sudo systemctl enable root-suspend.service
sudo systemctl enable root-resume.service

Mám to odskúšané na distribúci GNU/Linuxu ArchLinux, vychádzal som z ArchLinux wiki.

[MadCatX]

Jde to i jednodušeji:

#!/bin/bash

case $1/$2 in
        pre/*)
                echo "System going to $2" >> /stest.txt
                ;;
        post/*)
                echo "System has woken up from $2" >> /stest.txt
                ;;
esac

Skript libovolného jména stačí umístit do /usr/lib/systemd/system-sleep a nastavit ho jako spustitelný. Inspirace též z ArchWiki.

[jany2]

Skusil som to, ale neviem preco to nefunguje. Mas tiez tu istu DVB kartu ?

[nobody]

radky s ExecStart zkus provizorne zmenit na:

# v root-suspend.service
ExecStart= - /bin/echo usinam $(/bin/date) >> /tmp/spanekd.txt

# v root-resume.service
ExecStart= - /bin/echo probouzim $(/bin/date) >> /tmp/spanekd.txt

po probuzeni zkontroluj obsah souboru /tmp/spanekd.txt, pokud tam budes mit oba radky, mas jistotu ze se ti pri uspavani/probouzeni ty service opravdu poustej..

[Andrej]

Zároveň by bylo super nahlásit bug, protože driver od toho DVB modulu by měl být schopen vypořádat se korektně s uspáním a probuzením počítače. Pokud to neumí a vyžaduje takovýto podivný zásah, je v něm zjevně něco špatně a každému by prospělo, kdyby to někdo opravil.
