I am trying to run this command constantly to turn keyboard repeat on:

gconftool-2 --set /desktop/gnome/peripherals/keyboard/repeat --type bool 1

Because the keyboard repeat constantly turns off on my Dell 1420n laptop. This is very annoying. This happens with Jaunty and Intrepid - but not Gutsy.

However if I put that command into crontab, it refuses to run.
If I put that command with "watch", it works great.

How do I get it to run constantly if crontab won't allow it?
