In previous versions I could tweak the keyboard repeat delay and speed by going to
Settings > Keyboard > Typing. Now in Ubuntu Gnome 16.10 (with Gnome 3.20.2) that panel seems to be missing.
How can I configure those settings in this version?
Ok, I've found it. Those settings were moved to Settings > Universal Access > Typing > Repeat keys then you must click the Repeat keys row ot show a pop-up dialog of the setting.
Additionally, speed works in reverse. The lower the speed, the faster the repeat rate..
The same works in Ubuntu 17.04 and 18.04.
I'm a Ubuntu 18.04.3 User.... and not a techie. I tried changing the kdrate in terminal. I was told it had changed, but it didn't change the slow keyboard input. This low tech method worked for me. Go to "Show Applications", where there's a "InputMethod" utility, which has a keyboard as the icon. Open this.... ignore the warnings. Select "Yes" then you are presented with a list of options. The one which worked for me is "auto activate IM with @mark for most locales". You need to reboot your PC/laptop. Then you can go to "Settings" "Typing" and then click on "repeat keys" and "cursor blinking". Both these options have sliders which you can use to speed up and slow the keyboard and key strokes. I tried looking at the Keyboard Documentation..... I didn't understand it, so I hope this answer works for Ubuntu users like me.
