#175649 — Plasma: keyboard crash

Hi folks,

from time to time in plasma 5 I have the problem, that the keyboard stops its 
function. Is there a way to restart the keyboard without restarting plasma?

Thanks for any hints.

Best

Hans

How have you determined that the problem is with plasma 5 and not
something else? What happens when you run a different desktop
environment?

Oh, sorry, yes of course. 

This is a notebook, running debian testing, proprietrary nvidia driver and 
effects active in plasma.

This behaviour appears from time to time, and it is a little bit annoying when 
editing fields on a web page or writing a larger document in libreoffice.

Thanks for your response.

Hmmm....is it hardware or software?
Let's check hardware...(I'm betting on something funky on the hardware end)
Do you have (or can you borrow) an extra USB keyboard and mouse that you can 
plug into the notebook and use for a while.  Does this make the problem go 
away?  If the problem goes away, it sounds like a hardware problem to me.

The mouse is going on working. It is  a software problem. Plasma at all seems 
unstable, as from time to time it crashes, but is automatically restarting 
again. 

But that is another story. However, is there a way, to restart the keyboard, 
without leaving plasma? When the keyboard crashes, I can still open a console, 
start an onscreen keyboard (ie. kvkbd) and could use the mouse for input.

A similar problem is at https://bbs.archlinux.org/viewtopic.php?id=203724,
and a recommendation was to restart the relevant module:

> rmmod atkbd ; modprobe atkbd reset=1

I'm not sure what module is driving your keyboard, but "lsmod" should list
the loaded modules, and you can probably guess/tinker to find the module,
like maybe "uinput" or "hid" or "hid_generic" or "usb_hid" or "usbcore" or
....

However, I'd recommend you do the command in a single line, like above,
rather than separate lines, in case you kill your mouse in the process and
lose the ability to mouse-type.

More info. please.  Is this a desktop PC, a laptop, or what?  If a desktop, is 
the keyboard USB or PS/2?  How about your mouse and its 
operation...usb...ps/2...integrated with keyboard...touchpad...etc.  Does the 
mouse stop working as well?
