temature file not found on /proc/acpi/thermal_zone


i'm under slackware-current, or 10.1 if u want. i'm using 2.6.12 kernel, just compiled it and included acpi thermal option at compile time, and not as a module. i have a P4 2.4 512DDR and have only slack-linux on it.

my problem is that i want to monitor my CPU tempature with a nice app under KDE 3.4.1 named KTempature. it requires /proc/acpi/thermal_zone/THRM/tempature.

now i don't have a THRM dir in there. i looked over the acpid daemon man page and saw a couple of things there and understood how things work, i think, but i could not find the issue or a solution to this.

any sugestions or help will be greatly apreciated!

thanks.

As far as I can tell, Ktemperature monitors system temp, which is not CPU temp. On my setup, THRM returns a temp of 22 Celsius. My CPU temp is 38 Celsius on a different sensor.

Anyway, back to your question: if you compiled THRM into the kernel, you should be able to see if it's being loaded in /var/log/dmesg. Look for a line something like
Code:
ACPI: Thermal Zone [THRM] (22 C)
If it's not there, check in your kernel config (/usr/src/<kernel>/.config) in the ACPI section for a line like
Code:
CONFIG_ACPI_THERMAL
Check what the option is (m,y, or not set). I know you said you compiled it in, but it's always best to troubleshoot from the bottom up
