Suspend seems to cause my mouse and keyboard to stop working. When I resume my laptop from suspend/sleep the mouse and keyboard are un responsive. The mouse does not move and I cannot type my password in to log back in.
A google search directed me to this question from 2014: http://askubuntu.com/questions/483416/keyboard-and-mouse-unresponsive-after-suspend, where it showed that this can be fixed by reinstalling my input devices using
sudo apt-get install --reinstall xserver-xorg-input-all
but when I enter this code I get the error:
> Reinstallation of xserver-xorg-input-all is not possible, it cannot be
> downloaded. 0 to upgrade, 0 to newly install, 0 to remove and 0 not to
sudo apt-get install xserver-xorg-input-all
gives a message that xserver-xorg-install-all is already installed with the latest version.
