Cpu scaling (now) not working.. what happened?

Asked by karlpiuemeno on 2007-11-03

I don't know what happened... but now amd cool&quiet isn't working in my gutsy.

If I try with: sudo powernowd.... I have this error:
powernowd: PowerNow Daemon v0.97, (c) 2003-2006 John Clemens
powernowd: Found 1 scalable unit: -- 1 'CPU' per scalable unit
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq: No such file or directory

PowerNowd encountered and error and could not start.
Please make sure that:
 - You are running a v2.6.7 kernel or later
 - That you have sysfs mounted /sys
 - That you have the core cpufreq and cpufreq-userspace
   modules loaded into your kernel
 - That you have the cpufreq driver for your cpu loaded,
   (for example: powernow-k7), and that it works. Check
   'dmesg' for errors.
If all of the above are true, and you still have problems,
please email the author: <email address hidden>

If I install powersaved, launch powersaved...remove powersaved and reinstall powernowd, it works!.. but as I reboot, powernowd turns back to not work......
Something is missing...

if I try: cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
cat: /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq: Nessun file o directory

(no file or directory)

Si sono italiano, se preferisci utilizziamo la nostra lingua.

in attesa di tuo riscontro in merito sto cercando una soluzione :)

Massimo Forti (slackwarelife) said : #4

da terminale digita il seguente comando

 dmesg | grep powernow

posta il risultato. Hai un AMD 64 bit con tecnologia C’nQ, devo capire se viene letto il modulo relativo. Grazie e ciao

provando questo comando, non spunta nulla..... sia come utente sia come root....

nel frattempo ho provato reinstallando il pacchetto ubuntu-desktop (non si sa mai che per strada si era perso qualcosa) ma niente da fare.. il problema non si risolve...

ho provato a rimuovere virtualbox (non si sa mai di una incompatibilità di moduli) ma niente, non cambia nulla....

karlpiuemeno (karlpiuemeno) said : #6

Niente, problema risolto: ho reinstallato ubuntu e buonanotte.. tanto la home ce l'avevo a parte.. in pochi minuti tutto rimesso come prima :)

grazie lo stesso, ciau!
