I’m quite new in the linux world and I just got openSUSE Tumbleweed with KDE installed.
I absolutely love it, you guys are doing a great work.
I’m using a Lenovo P14s Gen2 (Intel version with Nvidia T500) and everything worked out of the box.
(That wasn’t the case with Ubuntu and Linux Mint; MX Linux worked quite well but had some other issues.)
However, the fan of the notebook is driving me crazy. Obviously not a linux problem, but Lenovo did some really bad work here.
I’m aiming to adjust the fan speed with thinkfan, but i wouldn’t start.
I’m getting either the ERROR: /sys/class/hwmon/hwmon0/temp1_input: No such file or director
or ERROR: Error scanning /sys/devices/pci0000:00/0000:00:03.1/0000:27:00.0/hwmon: No such file or directory
I would also go for another software to control the fan speed, if there is anything reliable.
I’d very much appreciate your help!
I’m trying to switch to linux already for quite some time to finally emancipate from windows, but I’m always getting thrown back by issues like these. This time I really want to stay with linux.
Although I’m not able to help you with your current issue, I think it’s useful for you to know that “we” are not the ones working on openSUSE. We here are users like yourself, nothing more. There may be some here who are in fact woking on openSUSE, but mostly, we’re just like you, users of a really good linux distribution that we love.
When I look into the folder i get that there’s indeed no temp1_input.
sudo ls /sys/class/hwmon/hwmon0/
device in0_input name power subsystem uevent
I searched for an older kernel version in Yast - preferrably 5.2, since they claim it was working in 5.2, but I didn’t succeed. There’s no older version than 5.16 in Yast, or I am too stupid.
At this point I find myself again stuck.
The writer of the blogpost in the first link says:
Although, if you’re not very fond of Debian, I can recommend installing Fedora 35 on your laptop. I’m running it right now on my P14s and it works great, I don’t even use thinkfan anymore, since the fan is quiet out of the box.
At least it would be a distro that I haven’t tried out yet lol!
The arch doc seems to state there is a thinkfan non-lm-sensors option which makes available /proc/acpi/ibm/fan or /proc/acpi/ibm/thermal. I often consult the arch docs even though I use Tumbleweed (arch being too labour intensive for my tastes).
In my own non-Lenovo non-noteboot desktop I’ve just fallen back to manually configured fan speed steps defined in the BIOS and only use the Linux sensors for monitoring.
I trashed my install so I can’t cut and paste the terminal output but my recollection was that it said there were no PWM-controllable devices available (or maybe no user-configurable PWM devices).
[Insult to injury, two other long-standing HW problems have gone away with the switch to Fedora – display behavior when docked to a Lenovo mechanical dock and audio over HDMI. I wonder if RH/Fedora just spend more time on Lenovo hardware.]
