Looking at a Ubuntu 4 box of mine:

,----[ Output ]
| roy@dialup:/etc/X11 $ ls
| app-defaults             rstart            xinit       Xsession.options
| cursors                  sysconfig         xkb         xsm
| default-display-manager  X                 Xresources  Xwrapper.config
| fonts                    XF86Config-4      xserver
| gdm                      XF86Config-4~     Xsession
| rgb.txt                  XF86Config-4.bck  Xsession.d

So, as you can see, there is a .bck file. Try the following commands
(assuming similar/identical filenames):

,----[ Commands ]
| cp  XF86Config-4  XF86Config-4-my-new-rotten-settings
| cp  XF86Config-4.bck  XF86Config-4

Now, log out and log in again (or simple reboot) to restart X. I can't recall
how this can be done easily in GNOME (CTRL+ALT+BACKSPACE in KDE). Any joy?
Just going to the screen resolution submenu /may/ suffice, without even
restarting X, but somehow I doubt it.

All your settings files (excluding a few system (global) settings/files)
exist in your home directory. It is a good habit to keep (dump) a copy of
all your settings every now and then. In case something goes amiss, you can
revert back to the old state. I suggest you compress all your dot files,
which contain application/module-specific settings:

,----[ Command ]
| zip -r -9 ~/mysettings-`date +%Y-%m-%d`.zip ~/.[0-z]*


,----[ Command ]
| tar czvf ~/mysettings-`date +%Y-%m-%d`.tar.gz ~/.[0-z]*

Hope it helps and good luck,
