Manually adding new WM to KDM

Hi all, does anybody knows how to manually add a new window manager to KDM drop down menu so that it can lunch it? Adding an item to KDM is quite simple (through the Control Panel) but I don't know how to execute the WM. I'm using SuSE8.0 and I really don't understand how the Xsession script from SuSE works. Cheers, Ale. _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
