Non dimenticare di chmod + x quel file, rendilo eseguibile.
C'è un'altra soluzione senza rtcwake, usando wakealarm in / sys / class / rtc / rtc0. Usa il codice obsoleto nelle funzioni pm (/ usr / lib / pm-utils) dopo i commenti # poiché il kernel non supporta direttamente ..., (quindi il kernel corrente (dopo 3.6 qualcosa) supporta direttamente). Ripristina quel codice e inserisci la parte do_suspend () invece di do_suspend_hybrid ().
Codice obsoleto (sospendi quindi ibernazione quando viene chiamato suspend_hybrid):
# since the kernel does not directly support hybrid sleep, we do
# something else -- suspend and schedule an alarm to go into
# hibernate if we have slept long enough.
# Only do this if we do not need to do any special video hackery on resume
# from hibernate, though.
if [ -z "$SUSPEND_HYBRID_MODULE" -a -w "$PM_RTC/wakealarm" ] && \
check_suspend && check_hibernate && ! is_set $HIBERNATE_RESUME_POST_VIDEO; \
then
SUSPEND_HYBRID_MODULE="kernel"
do_suspend_hybrid() {
WAKETIME=$(( $(cat "$PM_RTC/since_epoch") + PM_HIBERNATE_DELAY))
echo >"$PM_RTC/wakealarm"
echo $WAKETIME > "$PM_RTC/wakealarm"
if do_suspend; then
NOW=$(cat "$PM_RTC/since_epoch")
if [ "$NOW" -ge "$WAKETIME" -a "$NOW" -lt $((WAKETIME + 30)) ]; then
log "Woken by RTC alarm, hibernating."
# if hibernate fails for any reason, go back to suspend.
do_hibernate || do_suspend
else
echo > "$PM_RTC/wakealarm"
fi
else
# if we cannot suspend, just try to hibernate.
do_hibernate

Consigliato. Ancora più facile da usare uswsusp mentre allo stesso tempo massimizza il vantaggio di s2both, ovvero s2both quando viene sospeso. Inserisci il codice ripristinato nella parte do_suspend () del modulo uswsusp (/usr/lib/pm-utils/module.d).
Codice ripristinato (suspend_hybrid quando viene chiamato suspend):
WAKETIME=$(( $(cat "$PM_RTC/since_epoch") + PM_HIBERNATE_DELAY))
echo >"$PM_RTC/wakealarm"
echo $WAKETIME > "$PM_RTC/wakealarm"
if do_suspend_hybrid; then
NOW=$(cat "$PM_RTC/since_epoch")
if [ "$NOW" -ge "$WAKETIME" -a "$NOW" -lt $((WAKETIME + 30)) ]; then
log "Woken by RTC alarm, hibernating."
# if hibernate fails for any reason, go back to suspend_hybrid.
do_hibernate || do_suspend_hybrid
else
echo > "$PM_RTC/wakealarm"
fi
else
# when do_suspend is being called, convert to suspend_hybrid.

Con uswsusp, possiamo vedere l'avanzamento della sospensione / ibernazione e il processo inverso visualizzati nel testo, anche se possiamo interromperlo premendo backspace. Senza uswsusp, la sospensione / ibernazione appare e scompare in modo fastidioso, specialmente quando viene attivato il wakealarm ed esegue l'ibernazione (disco s2 in uswsusp). Impostare il periodo di sospensione prima dell'ibernazione nella solita posizione sul file delle funzioni pm.
