It can be done manually with 'killall -SIGUSR1 > cpuspeed' I use Speedfreq, when I'm on battery, I just use acpid to detect the AC being pulled off and do a speedfreq -p powersave (checkout the cpuspeed help/man page) Also, I noticed that (for me) if I boot up using the battery, acpid won't detect this and thus, I created a initscript to detect if the AC is on and call speedfreq accordingly. > > Someone mentioned a Gnome CPU frequency applet, I can't seem to find it > > on my laptop. Is this something I need to install separate? You need to DL it and install it yourself. It's Called CPU Frequency Scaling Monitor.
