Touchpad freezing ding sound clicking left or right button

Running Ubuntu Mate 16.04 LTS Acer 64bit laptop with a touchpad. Mate will be working fine then all sudden mouse pointer will not move. If I click left or right mouse button all I get is ding ding. I can use tab and enter to navigate, but have to reboot to get touchpad working again. Can’t find touch pad anywhere in dconf editor. Please help.

Hi @toddbmobile,

have you done a full system update?:

Have you tried running the following terminal commands? (Ctrl + Alt + t):

sudo apt-get --fix-missing install

The above command downloads and installs any missing packages on your system.

sudo apt-get --fix-broken install

The above command downloads and installs any broken dependencies on your system.

Thank you for the suggestions. I will give them a try and let you know.
