[quote]:I think I know what you mean, if you were upgrading from the knoppix install, and replaced the x-window system with the newer version in Debian, then you need to replace the /etc/kde3/xserver script with the debian version.

I am completely new to linux: could You tell me how to do it?

Thanks

PS. On restart is really slow especially when it comes to: STARTING NIS SERVICES YPBIND [BINDING TO YP SERVER...!
Also: RUNNING NTPDATE TO SYNCHRONIZE CLOCK, takes long time!

Thanks again
