I ran Ubuntu Karmic but switched from Gnome->KDE. And yes, I know CPU scaling works on this system (it ran Windows earlier)
But you missed the point - this kind of pinching, poking and tweaking shouldn't be necessary.
Sorry I am a recent ubuntu convert , and yes it does pee me off on occassion . Infact after weeks of messing about had to downgrade to 8.04 as the intergraterd ati gpu in my laptop not supported anymore (or by windows for that matter) , but as to fiddling, if you have used Amiga, and I assume you have given the nature of this site , its part of the fun.
But as i posted on another thread. Enable restricted drivers for gpu and wirelss and everyhting works out of box.
cheap no name bluetooth just works and connects to my home theatre for sound. Creative zen vison m sycs out of box etc etc etc connect new printers, installs ( couldnt get it to work with windows 7) , low level ink warning etc work .
I tired some distros years ago and didnt get anywhere. With ubuntu 9.04 or 9.10 its pretty much as polished as windows if you ask me
