[Résolu] Disparition de la gestion fréquence CPU (suite à manip ?)

Salut,

J'ai un problème, à savoir que depuis ce matin mon portable ne gère plus les changements de fréquence de mon CPU (AMD Sempron 3200+)...

Au démarrage, j'ai droit à une fenêtre avec :

CPU frequency scaling unsupported
You will not be able to modify the frequency of your machine.  Your machine may be misconfigured or not have hardware support for CPU frequency scaling.

et le CPU tourne à 997 MHz en continu (au lieu de 1.8 GHz max)...

Pourtant jusqu'ici tout allait bien... Quand je fais sudo modprobe acpi j'ai l'erreur :

FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.12-10-k7/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

Et quand je fais sudo modprobe powernowd :

powernowd: PowerNow Daemon v0.96, (c) 2003-2005 John Clemens
powernowd: Found 1 cpu:  -- 1 thread (or core) per physical cpu
/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,
   and that it works. (check dmesg for errors)
If all of the above are true, and you still have problems,
please email the author: clemej@alum.rpi.edu

Un dmesg me donne :

La seule chose que j'ai modifié hier (je crois) est que j'ai voulu faire en sorte que le script décrit [http://forum.ubuntu-fr.org/viewtopic.php?id=31518]ici[/url], censé éteindre le portable en cas de batterie faible (et validé en console), soit lancé automatiquement au démarrage. J'ai pour cela effectué les commandes :

sudo chmod +x /etc/init.d/fin_batterie
sudo update-rc.d fin_batterie start 20 2 3 4 5 .

Me disant que le problème de CPU venait peut-être de là, j'ai essayé de le désinstaller par :

sudo update-rc.d fin_batterie remove

mais le problème persiste... J'ai également tenté un

sudo base-config

mais rien non plus.

Re : [Résolu] Disparition de la gestion fréquence CPU (suite à manip ?)

J'ai supprimé la solution que je croyais avoir trouvée, elle n'était pas bonne...

Par contre, le problème vient effectivement du script, qui supprime le répertoire /sys/devices/system/cpu/cpu0/cpufreq/, je comprends pas pourquoi (discussion en section programmation).

Donc après de nombreux redémarrages et expérimentations je pense avoir trouvé la solution optimale : il suffit d'enlever l'applet de gestion des fréquences du CPU du tableau de bord, puis :

sudo apt-get remove powernowd
sudo apt-get install powernowd

et enfin de remettre l'applet sur le tableau de bord.

Voilà.
