How to change key behavior in ubuntu?

Question

linux

Everything worked fine until one day the keys began to behave strangely) In general, the problem is with backspace and arrows. When pressed and held, backspace deletes only one character, and the arrows also move only one character. Checked on Windows (it costs the second system), deletes while you hold. How to solve the problem?

Answer 1

In what application does this happen and what version of Ubuntu do you have?

Answer 2

I solved the problem by updating the kernel to version 4.15.0
