In my case I upgraded from Hardy to Intrepid final and it used to have KDE 3.5.10. After the upgrade, I can't enter in KDE4 after boot, nevertheless I could starting it manually with "sudo /etc/init.d/kdm restart" . I was trying to fix this when I applied an updated package the Tuesday from repos and after that there is no way to login in KDE4 anymore, when I tried the command "startx", it begins to start the X server but then it suddenly died. When I tried to do it with the "sudo /etc/init.d/kdm restart" command, I can get the session manager, choose a session and write my pass, try to login and it died again one more time. Reading the Xorg.0.log I noticed that in my case is a problem with the SiS video driver, but I post it here because I think the problem is close related. I attached to this bug repot the xorg.conf, Xorg.0.log and kdm.log files. If you need another file please let me know. By the way the file .xsession-errors is empty.
