Recently I figured out that my KDE 4 was eating up a hell lot of resource on my ol' AMD Athlon XP 2400+ . Finally, I decided to downgrade my Desktop environment to KDE3.5 since it won't use so much of my machine's resource for all the flash offered by KDE 4.
Here, I'm compiling KDE 3.5.10 from it's sources directly. I'm on a Fedora Core 10 box and used to rely upon Yum's auto-updates for KDE updates. Now what I'm concerned with is, whether or not would I find KDE 3.5 updates in the same repository and if I shall have to add some other repository location for yum?
