Kde problems

[david walcroft]

Hi,
I've reposted as I need to try and get a response as it's a ridiculous
situation reinstalling because I cannot get kde to work as it should.

I'm using fc12-86_64,my problem is when ever I logout/login or 
shut-down/reboot I lose kde,it will not start,only a blue screen.
and no desktop.Sometimes I get the error 'cannot access 
/usr/bin/autorun: no such file or directory' so I cp -r /usr/bin/autorun 
from my backup and logout/login with no result.
An install a while ago my sys. booted into a default desktop not my 
usual desktop,I found out that kde was not reading my ~/.kde file,I cp 
-r a copy from ~.kde.old ~.kde but on logging out/in the ~.kde file was 
over written.The only solution I've had is to reinstall the system.
I've got no idea how to troubleshoot these problems.Help would be 
appreciated.
