My keyboard had been working properly for 4 months, but all of the sudden, the settings for Delay and Speed in System Tool → System Settings → Keyboard → Typing → Repeat Keys got ignored.

I have restarted the machine, but it didn't help.

To troubleshoot, I've even set the delay to zero, but there is still about a 1.5 second pause. Then I set it to the maximum value; there's still the same 1.5 second pause.

In addition I have attempted to rectify this from the command line

$ sudo kbdrate -d 250 -r 22
[sudo] password for user1: 
Typematic Rate set to 21.8 cps (delay = 250 ms)

Once again, the delay and rate remain unchanged after running this command.

I am using Ubuntu 12.04 with GNOME Classic.

What setting exactly? CCSM is the compiz settings manager. What have you set up? What have you changed? Are you sure you are using compiz? – terdon Apr 1 '13 at 17:14
I corrected the question. – javadba Apr 1 '13 at 18:01
Thanks for the edit, now what is this delay you have set to 0? There is a pause when doing what? What settings are being ignored? – terdon Apr 1 '13 at 18:03
Typing | Repeat keys. – javadba Apr 1 '13 at 18:05

I finally found a way to change the keyboard settings:

xset r rate 250 30

Executing xset shows:

To turn auto-repeat off or on:
    -r [keycode]        r off
     r [keycode]        r on
     r rate [delay [rate]]

This command worked. kbdrate and the System Settings GUI tools did not.
