On my new Chuwi minibook X , with N150 cpu, Cpupower fails to apply its configuration,
both when started as a service, than when started manually.
Can it be this cpu is not (yet) supported ?
Some info:
cat /etc/default/cpupower
# Define CPUs governor
# valid governors: ondemand, performance, powersave, conservative, userspace.
governor='ondemand'
# Limit frequency range
# Valid suffixes: Hz, kHz (default), MHz, GHz, THz
#min_freq="2.25GHz"
#max_freq="3GHz"
# Specific frequency to be set.
# Requires userspace governor to be available.
# Do not set governor field if you use this one.
#freq=
# Utilizes cores in one processor package/socket first before processes are

# See man (1) CPUPOWER-SET for additional details.
#mc_scheduler=

Si sono verificati degli errori impostando i nuovi valori.
Alcuni errori comuni possono essere:
- Hai i necessari diritti di amministrazione? (super-user?)
- Il gestore che hai richiesto è disponibile e caricato?
- Stai provando ad impostare una politica di gestione non valida?
- Stai provando a impostare una specifica frequenza ma il gestore
userspace non è disponibile, per esempio a causa dell'hardware
che non supporta frequenze fisse o a causa del fatto che
il gestore userspace non è caricato?Its translation in english (by Google)

Errors occurred while setting the new values.
Some common errors are:
- Do you have the necessary administrative rights? (super-user?)
- Is the handler you requested available and loaded?
- Are you trying to set an invalid handler policy?
- Are you trying to set a specific frequency but the
userspace handler is not available, for example because the hardware
does not support fixed frequencies or because the
userspace handler is not loaded?uname -a

It sems that this cpu supports only the 'performance' and 'powersave' governors,
(as returned from the command cpupower frequency-info),
so that setting the 'powersave' governor in the cpupower configuration succeeds.
