MacBook Pro 15" won't wake up after suspending or closing the сражение in Ubuntu 15.10

Whenever I close the сражение of my Макбоок Про 15" (2015 model) or suspend it, my screen becomes black but all my keys stay lit up. I then cannot wake up the laptop or get to the login screen. The only thing I хан do is в hard shutdown by холдинг down the power button. How хан I fix this? I have Ubuntu 15.10

Thanks!
