I have Windows 7 and Ubuntu 10.04 running on a Dell Latitude D630 laptop and everything was working fine till I tried to change "Alt+Ctrl+Delete" to be system monitor rather than logout screen.

But I failed to change it, so I restored everything as it was before but I found that the Delete key was not working. I login to Windows 7 and it's working fine.

I tried to use the command xev to see what the key code for it is but it doesn't give me any response. The result is:

KeymapNotify event, serial 36, synthetic NO, window 0x0,
    keys:  18  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

I found a similar issue and the solution was to add this line to startup applications:

xmodmap -e "keycode 242 = Delete"

but I can't get the keycode for my delete.

Can anyone help?

Check again the place where you configured keyboard shortcuts. You probably accidentally bound Delete to a function with no immediately visible effect. Global shortcuts take effect before xev can see the events.
