Logout does not work

Hi,

I want to reply to what you say because I do not want to be some of these 
people telling problems and not giving further details :)

Would still be nice if someone like this would come round the corner :)

Okay, I should have mentioned details about the system. So here we go:

- Kubuntu 9.10
- with KDE 4.4 (out of ppa)
- and poulsbo driver (for the maximal available resolution of the EEE) ; psb-
kernel-source 4.41.6-0ubuntu1~1004jbs1

This is a very important information, as I asked myself what does happen 
during logoff. So to put it in other words, I imaginge the following chain:

logoff button -> session is saved -> session is terminated -> whole X server is 
restarted.

Well, I'm booting the system and then, I get to the login of KDM.  There is a 
script for this in /etc/rc5.d, so why this is happening is quite easy to guess 
:)

I have attached both Xorg.0.log as well as kdm.log further down this mail. 
This will make analyizis certainly easier.

> 2) The *DM is still there, but for some reason cannot restart X.

I tried after logging out:

$ ps  aux | grep kdm
root       812  0.0  0.1   3632  1024 ?        Ss   18:08   0:00 kdm
root      1595  0.0  0.0      0     0 ?        S<   18:08   0:00 [kdmflush]

So kdm seems to be still there. But why can't it launch X again? I am not that 
deep into the Xorg / ldm log files, I hope they might help to analyze the log 
files...
