Dotaz: Lid button nefunguje

[Smajchl]

Opravdu si s tim uz nevim rady. Ninstaloval jsem si Archlinux a ze zacatku fungoval lid button tak, ze kdyz jsem zavrel viko notebooku, zhasnul display, okamzite (a neprobudily se po chvili lampy, jak se to stavalo v Debianu).

Byl jsem nadmiru spokojen, potom jsem nainstaloval par programu a upgradoval system, par veci jsem nakonfiguroval a po tom vsem jsem si vsimnul, ze najednou se nedeje vubec nic, kdyz zavru viko.

Nejde to ani v distribucnim jadre ani ve vanilla jadre, kde je ACPI natvrdo a ACPI_BUTTON jako modul. Nainstal jsem acpid a chtel si to nastavit aby se to zhasinalo, ale at je monitor zavreny, nebo otevreny, vzdy je to stejne:

$ cat /proc/acpi/button/lid/C1E9/state
state:      closed

pokud uspim pocitac do RAMky, tak po probuzeni se zase porad objevuje open.

Musim podotknout ze v Debianu, ktery je nainstalovany na stejnem stroji to funguje i bez acpidu (driv se stavalo v Debianu, ze jsem musel zmacknout to tlacitko dvakrat, aby se opravdu zhasly lampy, protoze na poprve podsvetleni jen probliklo, ale ted to funguje naprosto skvele, je ale pravdepodobny, ze to nema s tim Archem nic spolecnyho).

Jak je to ale mozne, jak to vlastne funguje (bez acpidu) a proc to v tom Archu najednou nefunguje?

A jeste jsem zapomnel, ze v /var/log/acpid.log se porad objevuje:

a tohle 00000080 0000001e porad narusta, coz by asi nemelo, ale jde to klidne do 00000100 a vejs, vsimnul jsem si, ze kdyz drzim to lid tlacitko, tak se ty hlasky objevujou castejc, mozna jenom, kdyz ho drzim.

[Smajchl]

Tak jsem to jeste zkoumal a zjistil jsem, ze kdyz cerstve nabootuju pocitac, tak v Debianu:

Poprvy zmacknu lid tlacitko a nic se nedeje. Podruhy zmacknu lid tlacitko a od ty chvile se zhasina display jak ma

v Archu:

Poprvy zmacknu a zmeni se lid state z open na closed a od ty doby zustane porad closed at si mackam jak chci.

A kdyz v archu zapnu acpid, tak se porad dokolecka prepina monitor Externi -> Interni -> Externi + interni. Presne tohle se da v Debianu ovladat na klavesnici pomoci Fn + F4, coz v Archu nejde.

Nevite co je to za zaludnost?

[Smajchl]

Tak jsem uz mel chut to rozmlatit a zkusil jsem jako posledni vec, nez do toho kopnu postupne odebirat moduly a nic. Dal jsem teda do blacklistu vsechno co jsem nutne nepotreboval (moduly), restartoval jsem a ejhle uz display zhasina na jednicku.

Mohl za to modul video vubec netusim na co tam je ale ted uz to bez nej funguje.

Jedna vec me presto zajima, jak to funguje to zhasinani? Acpid tam neni zapnuty a presto to zhasina, dokonce to zhasina i kdyz jsem teprve v Grubu, hardwarove to neni, protoze to ten debilni modul video dokazal krasne zrusit.

Takze nakonec ten acpid na nic nepotrebuju Jupiiiiiiiiii funguje to Uz jsem ani nedoufal.
