Encontrou uma solução executando:
sudo modprobe -r psmouse
sudo modprobe psmouse
então eu coloquei em um script e coloquei em /etc/pm/sleep.d/ e chamei de 20_keyboardquickfix
#!/bin/sh
#put it in /etc/pm/sleep.d/ and name it 20_keyboardquickfix
#make sure it is runnable. by running "sudo chmod 755 20_keyboardquickfix"
#this scipts removes and then inserts the module psmouse, this is a #quick fix for keyboard working strangely after wakeup from sleep
