I know. It was kinda impossible to get there :)) . The failsafe session btw 
did not disable compositing (for me). I understand failsafe session as 
selecting fail-safe from the boot menu btw . Just in case.

xrestop did not show anything useful. I was able to start it through the 
Autostart feature and "konsole -e xrestop".

I could find out nothing about what it is that piles up in x11. I tried to 
valgrind x11 but i totally failed doing that. X11 startet but when i tried to 
put a kde session into the x server nothing happened. Someone experience doing 
that? Those test btw where done with VirtualBox. I could give kvm a try too.

Will try that.
