    Default KEYBOARD PROBLEM

    I am using KDE
    At various times and in any application, nothing appears when I press a key, but when I press it again, two characters appear.
    This happens with any key, even ENTER and mouse clicks.
    What can I do to solve this problem?

    1. Does this also happen when not using a GUI? – Does it also happen when typing in a VT (tty1 .. tty6)?
    2. How much free memory is available on the system?
    3. How are the I/O devices physically connected to the system?
    4. In the systemd Journal, are there messages related to either the Keyboard or, the Mouse?

    For the Keyboard only –
    KDE Plasma System Settings – section “Hardware” → section “Input Devices” → tab “Keyboard” –
    • Are the repeat rate and delay the default settings or, have the settings been changed?

    In ‘/etc/sysconfig/keyboard’ have the default parameter values of “KBD_DELAY” and “KBD_RATE” been changed?

    Many thanks for the reply
    I don't know what the reason is, but the problem did not occur again

    Physical connection not quite as it should be?
    • Sometimes a little bit of contact cleaner is needed to ensure reliable operation.

    Wireless keyboard? If so, are there obstructions between kbd and dongle? Also, low battery is a possibility.
