Well, this is partly correct, although I do not use compositing in KDE - because it will crash X. > > The problem that X freezes with KDE4 is more likely with webbrowsers but > > happend when using other programms too.

I am running: x11-base/xorg-server-1.10.2 x11-base/xorg-x11-7.4-r1 x11-base/xorg-drivers-1.10 media-libs/mesa-7.10.3 > Well, have a look at http://www.mail-archive.com/ubuntu- > b...@lists.ubuntu.com/msg1483058.html for an example how the open source > atidrivers can hang X with firefox.

This machine has an ATI Radeon X600 (RV380) 3E50 (PCIE). I have noticed that when I hover over the K menu, or when I select Log out/Shut down, I lose the wallpaper and the whole screen is filled with horizontal tearing/artifacts. This is what makes me thing that this is an xorg breakage rather than FF or KDE. KDE is of course heavier than XFCE or Fluxbox in graphic terms and this may be pushing things over the edge. -- Regards, Mick
