lately I've been experimenting in compiling the larger packages from source. So far, I've tried KDE, which surprisingly was very easy. First I used Konstruct, then I tried just compiling it by hand, and it just worked unlike the frustrating attempts at compiling gnome even with the help of garnome.

I hit startx and KDE was running decidedly faster!
Now i am trying to compile Xorg. Hopefully, by compiling these two huge packages from source with customized CLFLAGS will help my computer to just fly when i run it.

Compiling gtk will then be my next target. And then QT.

I would compile QT before kde, and Xorg before QT, in my preference order.
But if you use standard path for install, that should be fine

KDE faster. GOOD IDEA!!

I suppose that is better to remove Xorg, Qt and KDE before recompiling and installing the newest versions. How to proceed? Which of the current packages do I have to remove?

My slack is 10.1 with the standard 2.4.29.

How to proceed??

I've just seen that there's another thread about recompiling X. Anyway I think I'll need some help...

First make sure you have downloaded all the packages you need, then remove the ones you want to replace using pkgtool and proceed with the installation.
