[gentoo-user] Problem with Kde 4.1.X

[Nicola <neodarklight@gmail.com>]

Hi, 
I have searched on google and bugtrack for weeks for people with a similar 
problem with the new kde 4.1.X but I didn't find anything. I have some 
problem even to describe the problem beacause I don't know how to figure out 
what is wrong with my system. The real problem is that kde 4.1.X didn't start 
if I use kwin. I only get it start if I use another window decorator (for 
example compiz). I have tried with 4.1.3 and 4.1.4 but with the same problem. 
After the login screen i get the splash screen but at the end of the sequence 
I'm kicked out to the login screen. 
I need some advice to how and where begin to search for the problem. Which 
file I need to parse in search of the problem? Is there on the ML someone 
whith the same problem?

Xorg:1.5.3-r1
nvidia-drivers:177.82
kernel:2.6.27-r7

Intel Core2Duo 8400
nvidia geforce8800GT

Thanks

Nicola
