When I hold a key down, only several characters appear on the screen. In order to delete for example a sentence or few words, I need to press backspace many times.
I'd like to restore default behavior when you can hold a key and receive something like "rrrrrrrrrrrrrrrrrrrrr...", but now I have only "rrr" or in some cases "r". How can I achieve that?
I've tried solutions from here Keyboard repeat not working, but it's not working for me. I'm using ubuntu 16.04.
UPDATED: when I press Alt+F1 I can see that a new signal ^@ appears every second without any actions from me. I think that can cause the problem because it interrupts my keyboard holding. But I don't know who is sending that and why? Even when I unplug keyboard and mouse that signal is still appearing.
