Thread: Oneiric i386 - CPU scaling doesn't work?

i have hp dc7800 usdt, intel e4500, kernel 3.0.0.14, oneiric.

according intel, it's dual core 2.2ghz cpu. problem is, cpu frequency seems fixed @ 1.2ghz.

cat /proc/cpuinfo states:

code:

scaling governor 'ondemand'.

there way use 'full' 2.2ghz? , preferably dynamically?
