Titolo: Il computer non si spegne

Sul mio PC (linux Fedora 5 e kernel 2.16.x SMP poichè ho p4 con 
hyperthreading ) mi succede un fatto assai strano:
- Accendo il PC arrivo alla maschera di login e decido di premere il 
pulsante arresta ed il sistema si arresta e si spegne correttamente.
- Accendo il PC arrivo alla maschera di login ed entro in KDE (o GNOME) 
e decido di arestare il sistema, il  PC arriva a "acpm_power_off called" 
ma non si spegne.
Qualcuno può illuminarmi?
Grazie.

 ma non si spegne.
Ma lo spegni con il bottoncino sulla gui o scrivi "halt" in console?
In ogni caso sarebbe carino vedere cosa dice dmesg..
Ste.

> In ogni caso sarebbe carino vedere cosa dice dmesg..
Hum.. in realtà sarebbe da vedere il dmesg dopo che ti si ferma a 
"acpm_power_off called". In ogni aso ho dato un'occhiata al tuo e non mi 
pare ci sia niente di strano.
Però ora che ci pesno se sei fermo là l'unica cosa è vedere di trovare 
nei files di log di sistema (/var/log in genere) le ultime righe che 
dice prima di fermarsi su acpm_power_off_called
Può essere che ci sia qualche applicazione che viene lanciata solo udopo 
fatto il login, che bloacca acpi, tipo gestori di connessione, gestori 
di cpu o roba del genere

Forse è lui..
Comunque ripeto.. se ti si chiude correttamente se kde non vine 
lanciato, il problema è di un'applicazione che parte con kde.
potresti provare a fare un "cambia utente" e vedere se ti si spegne o no 
con la maschera per cambiare utente.
Di più non posso dirti. :-)
