You can copy the
.gconf folder from between users' home directories. Afterwards, you'll probably have to do
chown the whole copied directory recursively, so that all the contents are owned by the proper user. With this approach, you should test and see if such copying is both enough and not too much (that no private information got copied etc.) If this is not enough, look at the meaningful names of other "hidden" directories in user's home directory (those whose names start with a dot - you might need to enable viewing of them in your file manager). One good candidate would also be
Once you determine the directories that contain only settings which you'd like to be common for the two users, you can try making a symlink from one to another. That is (for each such directory) :
/home/user1/, backup the settings directory - for example by
- create a symlink to the other user's directory:
ln -s /home/user2/.gconf /home/user1/.gconf.
From now on, each change in settings will be stored in
user2's home directory only - applications run by
user1 will follow the symlinks and use the same settings.
