I recently switched to Ubuntu 18.04 and since then I have a lot of keyboard input lag, sometimes multiple seconds. I can type the words but it takes some time until they show on the screen.
I previously used Ubuntu 16.04 without any issues.
This error occurs in Terminal but also in my web browser.
Any idea where I could start debugging this problem?
So i tried the below suggested answers, thx for that. But still no solution. What I figured out is that this also may trigger by some keys more than ohters ... for example when im typing cdcdcdcd it appears really a lot.....
Also maybe important to know I use a different keyboard layout which I set with
setxkbmap de neo # (german neo layout) ( so cd is rl on asdf)
Altough this doesn't make a difference for the lag
Apparently this issues is only happening on the gnome/budgie desktop
Since I didn't found any solution to this problem, I figured out its time to move on ... anyway I switched to Manjaro now and have to say I am quiet satisfied no issues so far and a very clean and performant system.
However I would keep this questions open since some people still experience the same issue.. I hope you find a solution
