Ciao a tutti
quando clicco Spegni, sembra che faccia tutte le procedure, ma poi, quasi sempre (dico quasi perché una volta su 10 va tutto a buon fine) quando lo schermo diventa nero, il PC rimane acceso.
Prova a dare un'occhiata qui: http://forum.ubuntu-it.org/viewtopic.ph ... 49#p662749

Citazione
[ 0.000000] ACPI: BIOS age (1999) fails cutoff (2000), acpi=force is required to enable ACPI
Giusto ora ho provato ad editare il file "menu.lst" (posizione "/boot/grub") inserendo la voce "acpi = force" come di seguito
Codice:
title Ubuntu, kernel 2.6.20-16-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.20-16-generic root=UUID=1ee93e49-0489-42c4-8635-d1f3e5f014c7 ro acpi=force quiet splash locale=it_IT
initrd /boot/initrd.img-2.6.20-16-generic
quiet
savedefault
e adesso il PC finalmente si spegne!!!
[ 0.000000] ACPI: BIOS age (1999) fails cutoff (2000), acpi=force is required to enable ACPI

credo che la prima cosa da fare sia di togliere da Grub il quiet splash e leggere i messaggi di errore alla chiusura.
sudo gedit /etc/default/grub
