Holding "Backspace" deletes only one character

I don't know what I've done, but when I press and hold the key "Backspace" it just deletes only 1 character and stops. This is everywhere: in the console, Chrome, Text editors.

I'm running Ubuntu 14.04 LTS.

Solution 1:

Go to unity-control-center keyboard and make sure keyboard repeat is enabled

or use gsettings to change value:

gsettings set org.gnome.desktop.peripherals.keyboard repeat true

Solution 2:

The xset utility can be used to enable keyboard repeat. It works on the X.org level, so should override whatever the distribution is doing wrong.

To enable keyboard repeat, execute:

xset r on

For details, see man xset.

It worked for me on Ubuntu 18.04.
