  • Same here, with Apple Bluetooth Touchpad. After that upgrade it started disconnecting when I touch it with more than one finger. 15.04, still not working. Sep 30 '15 at 8:16

You can detect if you have some library problems by opening the terminal (CtrlAltt) and typing:

sudo apt-get check

If you get an error message (if not see the link below), you can solve it using:

sudo apt-get -f install

This will repair broken dependencies, that could be the problem.

If this doesn't solve the issue, you could try this solution (it requires more work):

Keyboard and touchpad stopped working after sleep

Hope you can solve it!
