Powertop - Enable CONFIG_INOTIFY

English Hardware
1

Hi

I am trying to maximise my battery time. I have installed laptop-mode tools and now have been using powertop to tune the laptop.

It has given me this specific message. But how do I do it?

Suggestion: Enable the CONFIG_INOTIFY kernel configuration option.
This option allows programs to wait for changes in files and directories
instead of having to poll for these changes

Secondly I am using the default display drivers as part of my gnome 11.4 install. There is no visual issue with the driver suse looks great and the effects all work. Just looking at it power wise is the RadeonHD driver more power efficient?

From lspci this is my exact ATI card.

01:00.0 VGA compatible controller: ATI Technologies Inc Redwood [Radeon HD 5600 Series]

I am reading that CONFIG_INOTIFY is something done when you configure your kernel just before you compile it. I also saw where it was said that CONFIG_INOTIFY was changed to CONFIG_INOTIFY_USER, but I would have to compile a kernel to see if that is true. I have a script you can use to compile a kernel, but kernel.org, is down right now which prevents you from directly downloading the kernel source file. Here are a couple of links to look at:

S.A.K.C. - SUSE Automated Kernel Compiler - Version 2.50 - Blogs - openSUSE Forums

SGTB - SuSE Git Kernel Tarball Creator - Version 1.11 - Blogs - openSUSE Forums

Thank You,
