corsac@hidalgo: sudo cpufreq-set -g ondemand                         [~]
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not
available,
   for example because of hardware which cannot be set to a specific
frequency
   or because the userspace governor isn't loaded?
