Cutting desktop power usage
- by steevc
I'm on a general energy saving mission. I've finally swapped my old CRT monitor for a LCD, so the next step it to optimise the PC power usage. It's using an AMD 64 X2 4600+ CPU which I know can trottle down, but seems to be running at a constant 2.4GHz.
A while back I heard about Granola. I've installed it, but when I try to run it I get
granola[10568]: Error opening scaling governor file '/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' in read mode
granola[10568]: Is cpufreq enabled in this kernel and do you have a CPU which supports DVFS?
granola[10568]: Can't manage DVFS for any CPUs
I'm happy to use other applications if Granola is not optimal or viable.
