Ubuntu :: Disabling Keyboard Repeat From The Command-line

Some Flash games don't work very well on Linux because when you hold down a key (such as one of the cursor keys) the Flash player sends the game multiple KeyDown and KeyUp events, leaving the game unable to tell the difference between a user holding a key or a user tapping a key quickly. (On other platforms it seems that typematic repeat generates multiple KeyDown events but not KeyUp events.)

Anyway, to work around this problem, I go to System->Preferences->Keyboard and disable "Key presses repeat when key is held down" when I want to play a Flash game, then put it back afterwards. I do this often enough that I'd like to set up some shortcut keys to change the setting. I figured out the following commands to turn it off and on again:

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

My problem is that when I have tried entering these on the command-line (in a gnome-terminal), X-windows seems to get confused and behaves as though I'm holding down the enter key. It doesn't stop if I press enter again. I tried pressing ctrl-alt-f1 to switch to a text console and it worked fine, but when I pressed ctrl-alt-f7 to go back to X it still behaved as though I was holding down enter. I had to press ctrl-alt-backspace to reset X before it would return to normal. I *think* it happens in particular when changing the setting from true to false. I'm running Karmic Koala with all the updates.
