Hi I recently bought a new computer and installed ubuntu 18.04 on my desktop.

Things okay when I type on Windows Os.

But when I type my keyboard in ubuntu OS on everywhere including terminal, chrome, etc, the texts do not appear right after typing and appear with delay.

I searched solution and checked slow key and Setting > Universal Access > Typing but I think the problem is not related to these settings.

Is there any way to fix these lagging problem?

  • I checked AccessX but it was already off and my computer specification is i7-10700k, msi z490 unify, rtx2080 super. and my key board is USB connected and model is cherry mx board 3.0s. I checked every USB port but nothing changed and did not check other keyboard models to my desktop.

This worked for me in the past on fresh installs
At a terminal type

sudo apt-get install ubuntu-desktop

And then

sudo apt-get install --reinstall lightdm

If no luck then try this; Remove the default gnome desktop and try unity

Sorry this first attempt didn't work for you
Open a terminal and type sudo sysctl vm.swappiness=0
This is only temporary until you reboot so don't worry.

  • sorry nothing changed. What kind of info you want which would be helpful to solve this problem? I reinstalled ubuntu but things are same – taegyu Aug 11 '20 at 15:58
  • Fist in Universal Access check that Typing Assist (AccessX) is off so that nothing can be selected there. Second tell us what computer it is, if it's a USB connected keyboard or other. – darth_epoxy Aug 11 '20 at 21:45
