where are the params?

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hi all, 

does someone know, where X gets its params? I searched everywhere, and cannot 
find it.

I am looking for this process, but cannot find the related config.

I am running kdm, and want to change vt9 to vt7.

Any hints?

Thanks
