I would strongly recommend doing this through SaX2 (under YaST). People who
descend to the level of text files too early find Linux rather discouraging
for no valid reason. Fine controls and old-styled command-line hacking may
be fine for the expert, but they deter the novice.

Also use the following tool if you have gone along these lines:

True. Copy the files using the file manager (Konqueror?) or, if you must:

cp /etc/X11/xorg.conf /etc/X11/xorg.conf~  (needs to access as root)

cp /etc/X11/xorg.conf /home/YOUR_USERNAME/

CTRL+ALT+BACKSPACE to restart X11 at any time.

Hope it helps,
