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.

Reset to default

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.

  • 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.
