Dotaz: Prazdne /proc/acpi/thermal_zone, HP Pavilion dv6750, Slackware 12.1

[bubak]

Zdravim,

chci zjistovat teplotu na procesorech, ale uz nevim kde dal bych mel hledat chybu. Zavedeny modul thermal mam, coretemp jsem zadratoval primo do jadra. A problem je, ze stale nic nevidim v /proc/acpi/thermal_zone. Nejdrive me napadlo, ze to treba nepodporuje bios nebo tak neco, ale potom, co jsem nabootoval LFS Live a jedna z prvnich veci, kterou jsem videl, byla vypis teploty na procesoru, z tehle myslenky seslo. Na googlu jsem narazil na par podobnych problemu, bohuzel jsem si nevsiml, ze by byl nejaky uspesne vyresen.

Predem dekuji.

Predpokladám, že celé sa to deje pomocou lm_sensors. Skontroluj, či máš nainštalovaný balík lm_sensors-2.* a ako root skús príkaz:

sensors-detect

Na konci to vyrobí /etc/sysconfig/lm_sensors, kde sú napísané moduly potrebné pre meranie teploty.

Slozku jsem kontroloval rucne. Lm_sensors jsem vyzkousel taky, zde se objevil pokrok, ale nevim jak moc velky a nevim jak moc to resi moji situaci. Nicmene prihodim par vypisu.

Myslim si ale, ze lm_sensors nevyresi problem s prazdnou slozkou /proc/acpi/thermal_zone. Za jakekoliv nakopnuti ci dalsi napady budu vdecny.
