Not sure about the set up in Ubuntu but I would assume that you are
not currently running your cpu in ondemand mode.
In Gentoo you would look in
it should say ondemand
What do you see in
#sudo vi /proc/config.gz
after CPU the CPU Frequency scaling
# APM (Advanced Power Management) BIOS Support
# CPU Frequency scaling
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT_DETAILS is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_GOV_CONSERVATIVE is not set
# CPUFreq processor drivers
this is my gentoo configuration (my laptop is not on at home so I can
not check it)
Some one with working on demand should post there section so you can
compare yours to theirs.
Hope this helps
