powertweak-0.1.16-3 and the -config packages.
The X11 UI just displays some data, but can't make any changes
( or I didn't figure it out )
The curses UI gives me menu with my PCI devices listed,
but selecting one has no effect. After I press RETURN
the same menu is displayed.
powertweak by it self didn't do anything.
The man page is not helpful.
The config file has 0 bytes length
Not a bug - powertweak won't let you make any changes unless you have hardware
it's familiar with (which currently isn't a lot, see
powertweak itself isn't supposed to have any output, it just activates the
settings you made in -config to speed things up.
