HOWTO: powernowd tip
I run Hoary on a laptop and it, per default, loads the powernowd daemon at startup. This was kind of annoying because I don't care about CPU frequency when my laptop is plugged in - especially when the cool screensavers were running. As such, I wanted mt laptop to not run powernowd when it's plugged in.
To accomplish this, I had to do two things:
1. Modify the /etc/init.d/powernow init script to check the ac power is disconnected before starting the daemon
2. Modify the /etc/acpi/power.sh script to start and stop the daemon appropriately.
come on guys, it's all ball bearings nowadays
