My laptop keyboard input sometimes working very slow for no reason, it delayed while I'm typing on it. But that problem doesn't exist when I'm using external keyboard. What I've done so far to resolve this issue are :
- Try different kernel version, I've tried kernel linux415, linux417, and 418.
- Try to use cli mode (assuming it's video driver or rendering issue)
- downgrade libinput to version 1.10.1 and xf86-input-libinput to version 0.27.1
- Try to use another distro, which are ubuntu 18.04 and kali
- Boot into my windows 10
point number 1,2,3 : the problem still persist
point number 4 and 5 : the problem resolved
Maybe it's just lag because of huge cpu load.. Well, I don't think so because I've been looking into htop and system-monitor while doing my job just to make sure the keyboard input lag is caused by huge cpu load, but it isn't.
