Which X environment are you using (KDE/Gnome/XFCE/etc...)?

If you go into a terminal and navigate to the users home directory and type
ls -a (you will probably need to be root or the user to do this)
it will list all the file in it including hidden files (files which start with a . there should be a directory called .gnome (if you using gnome) / .kde (if your using kde) or something simeler for other x environments.

you can either go into this directory and change the config files yourself. or you could copy them from another user (you will probably need to be root for this

try the commands
the first line on its own might work and load up with default setting and automatically create file but i cant guarantee that.

its probly worth backing up the users .gnome file first so (frome users account run)
this will save file onto the desktop where it will not be used by the WM to load setting
this will replace the first command
