Cannot set power profile or view fan speed

somebirb7190 · August 23, 2024, 11:13pm

I just made the jump from Ubuntu 22.04 on my Dell Latitude 5420 to Leap 15.6.
Something that I was able to do view my fan speed using lm-sensors.

Things I have tried so far:

Running sensors-detect pressing yes to every option
This forum post
Looking here

I know Dell support for Linux as a whole can be hit or miss, wondering if there is a/are package(s) I’m missing for my specific laptop that Ubuntu may have packaged as a default? I am aware of a i8kutils but that doesn’t have a candidate for 15.6 so I’m not sure what else to try.

My system:
. Dell latitude 5420
. 16GB RAM
. I7-1185G7
. OpenSuse Leap 15.6

Thanks

Did you try running “sensors”, like this (I’m running on a Dell Latitude 5500 … and yes, like it shows below, the fan is not running now)

I have indeed, maybe wasn’t specific about it. But yes after switching from Ubuntu to Suse, the fan speed section disappeared. Just want to know if there is a package I’m missing somewhere.

Thanks

Hmmm. I’ll show a couple of different discoveries, for my laptop (zypper - see Requires section … and then screenshot via Yast2)

    Which modules to load can be interactively detected as root by calling
    /usr/sbin/sensors-detect. Warning, before using the sensors the default

Reading this article I think it might help to install i8k:

I see there is a community package for tumbleweed but not for leap.

Hello,

I don’t know if this will work for you as I don’t have a Dell.

In order to read fan speeds on my Asus mobo, I must use the “acpi_enforce_resources=lax” boot parameter.

ox@orca$ grep ^GRUB_CMDLINE_LINUX_DEFAULT /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="splash=silent preempt=full quiet acpi_enforce_resources=lax noresume security=apparmor mitigations=auto"

malcolmlewis · August 24, 2024, 1:07pm

@marel The i8k modules is part of the kernel…

Some more info on what sensors needs (on my Dell laptop) …
“ldd” tells us the shared libraries loaded

user@machine :~>  ldd /usr/bin/sensors
        linux-vdso.so.1 (0x00007ffcc976e000)
        libsensors.so.4 => /usr/lib64/libsensors.so.4 (0x00007f944ae00000)

This one will certainly show a lot of detail about the files the command (sensors) wants to open and read (configuration files, etc) - might be a bit overwhelming :
