X desktop settings

[cr <cr@orcon.net.nz>]

(Sorry if I left any replies in previous threads unacknowledged - my 
motherboard died which caused a loss of communications for a couple of weeks).

Can anyone confirm this - are *all* the X desktop settings kept in the 
/home/<user> directory?

And is it therefore possible just to copy the whole of /home/<user> to a safe 
place before doing something really reckless and potentially likely to break 
things (like changing my desktop from KDE to Gnome for example) and if I find 
X hopelessy screwed up afterwards, can I just immediately copy my backup 
straight back to /home/<user> and get all my old settings back?

Or are there major 'look-and-feel' settings kept elsewhere?

Regards
