ACPI -t gives no result
Hello people,
I have installed Archlinux yesterday on a 3 years old Acer labtop, and it runs fine.
I chose Gnome 3 as display manager, didnt install any graphic driver (using defaults one).
So my computer is heating a lot, and i would like to check its temperature.
As i would have dont on my previous archlinux, i installed ACPI, and runned it. Here are some of my outputs :
$ acpi -b
Battery 0: Full, 100%
$ acpi -v
acpi 1.7
$ acpi -t
#nothing...So i can't check temperature with ACPi, and am using a recent linux kernel, so it seems i can't use lm_sensors.
Here are the datas i know about my kernel :

Re: ACPI -t gives no result
What do you mean "can't use lm_sensors"?

Re: ACPI -t gives no result
I read here that that lm_sensor was usable until kernel <= v.2.6.31. I use kernel v.4.x, zhich nis much newer, so i guess lm_sensor is not usable.
Should i try it ? I was worried that it may break my all new system.

Re: ACPI -t gives no result
As the head of the wiki page points out, that page is out of date because of the kernel 2.6 references.
A lot has changed in the intervening 4+ years.
Note, there's no guarantee that sensors-detect will find all the monitoring chips.

Take a look around under the /sys file system. On this laptop:

Re: ACPI -t gives no result
Your machine is not that hot. What make and model is it, and which processor do you have?
There are more than one way for the kernel to be aware of the operating temperature, and different laptops measure the temperature of different things. This laptop gets most of its thermal data from the processor itself. There is one sensor detected my acpi, but it is unclear what it is measuring. I also have available the hard drive temperature, but that comes through smartd, not acpi.
I assume you have run sensors-detect on your system. That is about the only way I know to "repair" ACPI.
But, let's back up a step. What really is at issue? The cores of your system are a bit warm, but not outrageously so. Room ambient temperature is mid-20s C, and your critical point is probably 100C. You are right in the middle.
You might want to use a tool like powertop. It provided much more insight to your system than will acpi. When you run that tool, you might also try tweaking your system with the controls on the tunables tab.
Edit: By the way, your city is one of my favorites
