which file switches window manger?

["ktb" <xyf peoplepc com>]

I hosed gnome trying to install helix, it complains about not finding a
fixed font.  My X session defaults to gnome when I use 'startx'.  I'm
thinking if I could switch the window manager to kde while in console, then
I could at least get X back.  This is my machine I use at work.  How can I
get this done?  I'm using 6.2.
Thanks,
kent
