Bug Description
Binary package hint: gnome-applets
Ubuntu 11.04
Ubuntu 9.10
gnome-applets:
Installed: 2.28.0-0ubuntu2
Candidate: 2.28.0-0ubuntu2
When unplugged, the tool from the panel works just fine and cpufreq-info shows the range of frequencies available as 800-2270. When the AC adapter is plugged in, this range is bounded to 800-800. Performance using Flash or any other semi-demanding task is terrible.
cpufreq-info output when plugged into AC power:
cpufrequtils 005: cpufreq-info (C) Dominik Brodowski 2004-2006
