It would also be useful to explain how to select the intel_pstate driver as
whilst the Kubuntu 14.04 kernel has it compiled in it does not select it by
default.
root(a)quad:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
acpi-cpufreq
root(a)quad:~# grep -i pstate /boot/config-3.13.0-43-generic
CONFIG_X86_INTEL_PSTATE=y
CPU is IVB.
Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz (fam: 06, model: 3a, stepping: 09)
All the best,
Chris
