I'll see about making this a proper config.
now it's either ubuntu packagers to patch E to remove that line or them not setting such governor parameter. The fits-all solution would be to make this a settings (easy) and expose it in some dialog (not so simple, but easy as well). I really dislike such governor option for the same reason Matthew Garrett: the faster you finish the task, the less power you use, less time with hot cpu... even less time hd spinning (for io+cpu bound tasks, like compile). -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (19) 9225-2202 ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
