Hi
I've noticed in system log the following message popping up from time to time.
gnome-shell[4119]: libinput error: event5 - Kingsis mouse: client bug: event processing lagging behind by 21ms, your system is too slow
What should I do about? What is the actual problem? Is my mouse too old and needs to be replaced? It is not a bluetooth mouse, but one with a tail.
/Jerome

I get the same thing. Mine is wireless, but it's a USB dongle.

Good to know I'm not the only one. I guess it is harmless and can be ignored? /Jerome

From my somewhat old Microsoft Wheel Mouse Optical 1.1A USB connected via an older hub:
gnome-shell[11094]: libinput error: event7 - Microsoft Microsoft 3-Button Mouse with IntelliEye(TM): client bug: event processing lagging behind by 28ms, your system is too slow
What should I do about? What is the actual problem? Is my mouse too old and needs to be replaced? It is not a bluetooth mouse, but one with a tail.
It is a feature: https://www.phoronix.com/scan.php?page=news_item&px=Libinput-1.16-RC
One comment blames lagging response on too many messages informing you your system is lagging.

Really? A system too slow to handle a mouse? How can it ever manage the other *far* more complex tasks?
To get 20ms of delay you would only need a tiny bit of paging every so often or a bit of cpu contention so that it delays your time slice because something is on the cpu the kernel wants to schedule you on..

I'm staggered. On a system that runs at 1,000,000,000 cycles per second (picking 1 GHz as a very conservative modern speed), which can be stated as 0.000,000,001 of a second per cycle, hardware (or Gnome?) can bog things down by that much?!
My 30 year old 16 MHz Amiga had no trouble whizzing the mouse about while taxing the system with other things.
I've got some old punch cards still laying around, if my PC is feeling a bit to stressed by me using the peripherals...
