no cpufreq on new install (32-bit)

[GregH]

I downloaded the MX-15 original CORE DVD .iso (from December), 32-bit. I ran all updates, and at first everything seemed fine. However, the computer gets very hot, and I discovered that cpufreq is not available. The "CPU Information" panel widget says that "no scaling driver is available".

cpufrequtils is installed and is the latest version. If I type cpufreq-info I get:

$ cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU
maximum transition latency: 0.00 ms.

This happens with both the default kernel (shows in GRUB as i686) and the alternate i586 available in the advanced options menu. The computer is a Dell Inspiron 700 with a single-core Pentium M cpu. cpufreq worked fine in the previous linux I had installed on this machine. Its "full" speed is 2.0 GHz, with a slower 1.0 GHz the rate at which it spent most of its time. Under MX it's been pegged at 2 GHz all the time.

What would I try to fix this?

$ uname -a
Linux InspironMX1 3.16.0-4-586 #1 Debian 3.16.7-ckt25-1 (2016-03-06) i686 GNU/Linux

Maybe you have to run as root the command described in the Users Manual (Section 4.7.6):

Code: Select all

sensors-detect

CORE is a stripped version of MX15.
It is designed so that you fill in the blanks.

You might have better result if you install the latest from here:
http://mxrepo.com/snapshots/
probably the http://mxrepo.com/snapshots/MX-15_May_386.iso

Then you can eliminate things you don't need.

In my MX15 there exists the following utilities:
cpufreq-aperf cpufreq-info cpufreq-set

Code: Select all

man cpufreq-set

offers info on setting the freq.

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

No idea how to interpret that message. You have a GUI alternative: click Start menu > System > System Profiler and Benchmark.

cpufreq-aperf
CPU doesn't support APERF/MPERF

The directory referenced in the man for cpufreq doesn't exist. Files should be in:
/sys/devices/system/cpu/cpu0/cpufreq

/sys/devices/system/cpu/cpu0# ls
crash_notes crash_notes_size microcode power subsystem topology uevent

Since it was a brand-new install, I decided to "take the easy way out" and downloaded the May snapshot, above. That worked, I now have the proper cpu speed scaling.

I didn't think the December CORE version is even online anymore.

Anyway, this thread should be in the modified MX section.
