Startx as a user with different config files

[lakicsv]

I bumped into the old X problem about the switching of resolutions without changing the desktop size (infamous scrolling problem). I learned that I can only switch between two different resolution with the same visible desktop size if I have two different xf86conf file.

Ok, accepted. But how can I start X (from the console or kdm, I would like to know both) with different XF86Configs (as a user, so do not try tricks like cp XF86Conf-1 XF86Conf in a scrip etc.)

Thanks Viktor

then you can start the X server by typing:
