Ubuntu – Ubuntu will suspend but won’t wake up

12.10macbook prosuspendwakeup

I installed Ubuntu 12.10 on an Apple MacBook Pro 9,1 Mid 2012 15inch non retina. Suspend suspends it but when I open the lid, it doesn't wake up. I tried pressing Ctrl + Alt + F1 but nothing works. Only the keyboard backlight switches on. What's the issue?

Moreover, I'm using the X org nouveau driver and not the official nVidia one. Please help. It is irritating to shut the laptop down every time.

Preferably try to fix your Hibernation function if its not working too. because in similar cases with "sleep problem",seems hibernate is more handy and workable solution.refer to this post

  • Test pci=noacpi as a boot parameter
  • take a look at /etc/default/acpi-support , probably it needs some changes

  • and if you are lucky, this command can help you:

    sudo chmod +x /etc/pm/sleep.d/*

all in all,it looks like this kind of troubles is related to hardware thing (Graphic Driver incompatibility or Power Manager) so why you don't try appropriate NVidia driver for your OS distribution?
