Keyboard and mouse stuttering on Ubuntu 18.04 with a new laptop

Question

On my LG Gram 17" (i7 8-th generation), I've got the problem in ubuntu. Keyboard and mouse sometimes are starting to stutter, repeat once pressed keys and lag.

Did someone else face this issue?

Found the workaround so far - setting the poll rate for keyboard and mouse to 1000 Hz (originally written he 125Hz by mistake):

sudo su
echo 1 > /sys/module/usbhid/parameters/kbpoll
echo 1 > /sys/module/usbhid/parameters/mousepoll

and replugged the usb hub.

As a permanent solution - these two parameters usbhid.kbpoll=1 usbhid.mousepoll=1 should be added to the end of the GRUB_CMDLINE_LINUX_DEFAULT variable in the /etc/default/grub file. So the variable should be looking like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.kbpoll=1 usbhid.mousepoll=1"

...and perform the:

update-grub

This appears to have fixed my mouse and keyboard stuttering problem on Archlinux (Manjaro). Thank you very much for providing the solution. – Ugo May 30 '20 at 18:31
Note that a polling rate of 1 is 1000Hz, not 125Hz. – John Eikenberry Dec 03 '20 at 22:56
As a security precaustion, remember to exit su – Peter Chaula Jan 26 '21 at 17:27
For those looking for more info on setting polling values, it's rate = 1000 / interval. Therefore 8 would be 125HZ. – jshook Apr 08 '21 at 12:26

@jshook so 0 is infinite (or undefined)? (my value is 0 - and it only stutters during high cpu usage) – inemanja May 17 '21 at 16:40
