Re: new kde on f13 is very noisy!

I have the same problem with KDE with nvidia drivers - it seems worse
with the latest Âones from rpmfusion, and worse in 4.5 compared to
4.4. (Not sure when the change came in, first betas of 4.5 seemed
fine).

There are a bunch of bug reports already (eg
https://bugs.kde.org/show_bug.cgi?id=234463) - though there seem to be
multiple issues and a lot of noise in the bug reports. For me, turning
off the blur effect helps, but not much. On my laptop I have switched
to gnome for the moment as it gives me approx 50% more battery life in
normal use (OO Word + calc, kmail, firefox, amarok, R etc) than same
apps under kde. KDE apps under gnome are a pain though (you have to
start kmail twice to get akonadi running first, super slow scrolling
in akregator etc etc).

Nouveau didn't work well for me last time I tried, but will probably
make the jump to F14 and try again sometime soon.

sorry!
M.

@moabi2000: Try out to reset your KDE settings as I mentioned before, then turn off the desktop effects

and see if KDE's behavior get's better. About the Opensource Graphics drivers a lot of people say that theyÂ

work great in F14!! Make the switch if you want.
