The last few months I’ve been wanting to adjust the fan speed on my laptop (a Lenovo 310-15ISK) through
fancontrol, but have been hesitant due to
# sensors-detectbeing able to “permanently damage hardware”.
However, I am able to run
$ sensorsto monitor temperatures (and nothing else apparently).
$ sensors pch_skylake-virtual-0 Adapter: Virtual device temp1: +31.0°C coretemp-isa-0000 Adapter: ISA adapter Package id 0: +30.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +28.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +29.0°C (high = +100.0°C, crit = +100.0°C)
That got me thinking, is running
# sensors-detectnecessary in order for
$ sensorsto be able to measure temperatures?
In other words, has
# sensors-detectbeen automatically executed during the installation process?
And if yes:
- Since no fan seems to be detected, does that mean I cannot adjust its speed?
- Does this make it safe to run it again, myself?
Recently, after upgrading with
pacman -Syu, I noticed a considerable increase in my laptop’s boot times and the following message started appearing:
[drm:wait_panel_status [i915]] *ERROR* PPS state mismatch
I think it is worth mentioning that -among other packages- the kernel got an upgrade too as can be seen in /var/log/pacman.log:
[2017-12-04 22:11] [ALPM] upgraded linux (4.13.12-1 -> 4.14.3-1)
That being said, I honestly don’t know if that’s what caused the issue, thus I’m posting here instead of the Kernel & Hardware subforum.
quietkernel parameter with
debugshowed that the boot hangs (for 40 seconds roughly) while
random: crng init doneis on the screen.
# bootctl update, which however, didn’t seem to change anything.
Not being sure whether the delay and the error messages are connected, what I care about the most is the delay. Is there any way to fix it? I thought about downgrading the kernel or switching to lts, but I am not really familiar with the procedure and would like to avoid it unless it is necessary.
- Both my
/homefolders are on an LVM2 partition, while my
/bootand my swap are on separate partitions. A while before performing the aforementioned upgrade, I took a snapshot of my

Excuse me for the long post, but I wanted to give as much info as I could.
