Public bug reported:
Thin clients installed by ltsp-build-client don't use their power
management capabilities by default, because scaling_min_speed is set the
same as scaling_max_speed in /sys/devices/system/cpu/cpu?/cpufreq .
The cpufrequtils package provides init scripts that automatically enable
the ondemand governor and set scaling_min_speed appropriately for the
hardware, and offers additional configuration via
/etc/default/cpufrequtils. This provides an immediate power use
improvement on thin clients, also reducing heat and (for fan models)
noise. It improves stability on hot Australian days, too!
As it's harmless on machines that don't support CPU frequency scaling
and offers big improvements on those that do, it'd be nice to see it
included.
** Affects: ltsp (Ubuntu)

ltsp-client should depend on or suggest cpufrequtils
