On Ubuntu 7.04 Feisty
1. create .Xmodmap file in your home directory

$ vi ~/.Xmodmap

2. write down below

! Switch caps lock and left control
remove Lock = Caps_Lock
remove Control = Control_L
keysym Control_L = Caps_Lock
keysym Caps_Lock = Control_L
add Lock = Caps_Lock
add Control = Control_L

3. load .Xmodmap file

$ xmodmap ~/.Xmodmap

4. next time you log in to your Gnome, it will detect .Xmodmap file automatically. Thus, next steps are not really necessary.

If ~/.xinitrc doesn't exist
$ cp /etc/X11/xinit/xinitrc ~/.xinitrc

In all cases
$ vi ~/.xinitrc
in the first line,
xmodmap ~/.Xmodmap
