kdm logout crash / black screen on next login on KDE4 (solved)

[Gregor A.]

A similar to the old logout problem with fglrx is back.

Now the problems starts on next login after logout on KDE4.

Black Screen and / or freeze

To solve the problem please edit:
vim /etc/kde4/kdm/kdmrc

and add:
TerminateServer=true


in section:
[X-:*-Core]

[X-:*-Core]
AllowNullPasswd=true
AllowShutdown=All
NoPassEnable=false
NoPassUsers=
ServerArgsLocal=-br -nolisten tcp
ServerCmd=/usr/bin/X
TerminateServer=true
