Almost right. I get the kdm screen, can type my password, and kde loads 
all right (mostly, though not always). I even get the mouse cursor. If I 
use the touchpad (or a USB mouse), I can usually click once , for 
example to open the menu, and then the whole thing freeze.

I have tried your suggestion before, but when I launch the kde with 
startx and it freezes, ctrl-alt-delete won't work and I have to reboot 
using the power button, so I never get any hints.
