Similar here. Touchpad freezes totally after suspend. I'm not sure about
the keyboard, as I stay in the graphic environment - I suspect it
doesn't quite work either. As for others, only a complete turn off -
turn on helps, reboot does not.

I have Fujitsu Lifebook E744, this happens with both openSuse Leap 15
and now Kubuntu 19.10, so this isn't distro specific.

I have seen recommendation for 
sudo apt-get install --reinstall xserver-xorg-input-all
but it did not solve this issue. 

Operating System: Kubuntu 19.10
KDE Plasma Version: 5.16.5
KDE Frameworks Version: 5.62.0

  Keyboard and Touchpad do not work after suspend/resume

Status in linux package in Ubuntu:

Bug description:
  My laptop is a Toshiba Satellite C850D with updated 18.04 installed.
  When resuming from suspend, I have no keyboard and touchpad.
  dmesg shows "i8042: Can't reactivate KBD port"

  This looks like a recurring problem, and is just like these:

  Here's the dmesg output from before and after suspending.

  This post also talks about this bit failing for a lot of people!

  Some of the function keys work, such as changing the screen
  brightness, but the key (fn+F5) does not turn the touchpad back on. I
  have not yet tried any of the suggested options, as results have been
  mixed, but I will.
