Problem:
When Ubuntu 14.04 or 14.10 comes back from sleep or suspend mode, the keyboard and mouse freeze. Nothing can be clicked or entered. The only way out is to force shutdown the system by pressing the power button. This is very inconvenient, rather very annoying. Because the default behavior in Ubuntu is that when you close the lid of the laptop, it goes in sleep mode.
In this quick post, we shall see how to fix this issue of mouse freeze after suspend in Ubuntu 14.04 and 14.10.
Solution to mouse freezing after sleep in Ubuntu 14.04
The issue is actually coming from Kernel upgrade. I am not sure of the reason why, but a re-install of input device driver seems to be fixing this issue.
sudo apt-get install --reinstall xserver-xorg-input-allThis quick tip was based on a question asked by an It’s FOSS reader, Dev. Try this quick tip and see if it works for you as well. In a similar issue, you can fix no Unity, launcher and dash after logging in to Ubuntu.
Thanks man! Its works fine for me on Ubuntu 18.04.2 LTS
This wont worked for me. At least i had working mouse before i`ve made changes to grub, after changing grub suspend didnt worked and neither mouse.
How can I perform any of these ideas if after every reboot the keyboard and mouse don’t respond?
Thank you very much for the tip, it worked perfectly for the several first times but after that the problem reappeared. Any clue about how to fix it?

“In /etc/default/grub, edited the line with GRUB_CMDLINE_LINUX_DEFAULT to say atkbd.reset i8042.nomux in addition to quiet splash which was already there before
Ran sudo update-grub and rebooted”
