Ubuntu Mate on Macbook 2006 doesn't go to sleep

Hi! I’m new here and I need your help :slight_smile: so help me please :heart_eyes:
I’ve installed Ubuntu Mate 16.10 on my 2006 MacBook Black Intel Core Duo 32 bit.
The MacBook is reborn but I still have some problems; the worst is that the MacBook doesn’t standby.
If I close the lid the screen turn off but the apple on the back stay on as well as the fans.
I’ve searched the internet but I havn’t found an answer.
Thanks a lot and sorry for my bad english

another strange thing is that crt + alt + t doesn’t open the terminal

You appear to have enough SWAP space to support suspend given the amount of RAM you have.
Have you checked the Power Management settings?

Right, it’s a mac so maybe it’s CMD+ALT+T or something like that.

Yes and all seems to be correct.
If I use OSX the sleep works.
I don’t know what to do because the sleep doesn’t work also niether if I click the button “suspend” on the menù…
Any ideas?
Thanks anyway
