Dear Sir/Madam, I am trying to install powerTop on my PC as I need to know the per process power consumption. I have the Ubuntu 11.10 installed on my PC. I installed the package available in Ubuntu Synaptic Package Manger but the power consumption in watts is not displayed. I get the message "no ACPI power usage estimate available". Is there any configuration settings that I am missing ? Could you please tell me on which version of the kernel is powerTop supported ? Also in the readme file it says "The patches in the patches/ sub-directory are required for PowerTOP to function fully." but I was not able to find this directory in the tar.bz2. Could you please also tell me where I will find the patches directory ? Thanking you, Srikanth
