Hi all,
I´ve been experiencing some weird behaviour keyboard-wise as of late.
The keyboard I´m using generally works fine.
xinput --list
says it´s a “Lenovo Lenovo Black Silk USB Keyboard”.
Normally it´s very responsive and each keystroke is answered by the respective output.
Yet - sometimes - I notice a keystroke produces no output at all; it seems the keyboard has gone unresponsive.
But just for one hit on (any) key. The next, let´s say, 5 or 6 hits work well again, when possibly the proceeding hit fails.
So: unresponsiveness isn´t a general pattern; just now and then a keystroke fails.
Hmm, I was wondering what brought that about, especially in view of the fact I´ve been using the keyboard for e.g. one or two hours without fail. And suddenly the partial unresponsiveness occurs.
Thinking about it when it last happened I noticed that xscreensaver
kicked in as I left the room for about half an hour.
Moving the mouse got the system running as per normal again but it´s exactly then when the phenomenon of the partial unresponsiveness made itself observable.
So I rebooted the system and everything worked fine again.
I´m not completely sure but it seems that the state the system was in (is it suspend?) might be to blame
What I tried to solve the problem without having to reboot was this:
xinput disable 'Lenovo Lenovo Black Silk USB Keyboard' && sleep 10 && xinput enable 'Lenovo Lenovo Black Silk USB Keyboard'
(from: mouse - Is there a way to "restart" the touchpad driver? - Ask Ubuntu )
The command itself worked but it had no effect at all. The partial unresponsiveness remained, so I had to reboot.
Does anyone know something about that phenomenon?
Any advice is highly appreciated.
Many greetings.
Rosika
