The Problem:
 
When Ubuntu 14.04 or 14.10 comes back from sleep or suspend mode, the keyboard and mouse freeze. You can't click or enter anything.
This forces you to shut the system down using the power button. This issue normally starts after a kernel upgrade.

Solution

 

The solution is to reinstall xserver. Open terminal by pressing CTRL-ALT-T and type or copy and paste the code bellow.

sudo apt-get install --reinstall xserver-xorg-input-all

There was an issue where the Desktop power manager  and Systemd power control we both trying to do the same thing and causing it to not work right...so 1 was trying to resume and the other wouldn't.

 

i think the remedy was to edit the    

/etc/systemd/logind.conf
HandlePowerKey=ignore
HandleSuspendKey=ignore
HandleHibernateKey=ignore
HandleLidSwitch=ignore 

Though this may be slightly different for Ubuntu...and for different DEs
