Bright entertainment trends with youth appeal.

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?

If you have a live CD try using it and boot-repair tool.seems theres nothing wrong with grub but it's good idea to change some boot options. These are some useful options mentioned by canonical itself..

  • vga=xxx

Set your framebuffer resolution to VESA mode xxx. Check here for a list of possible modes.

  • acpi=off OR noacpi

This parameter disables the whole ACPI system. This may prove very useful, for example, if your computer does not support ACPI or if you think the ACPI implementation might cause some problems (for instance random reboots or system lockups).

  • acpi=force

Activates the ACPI system even if your computer BIOS date is older than 2000. This parameter overrides acpi=off and can also be used with current hardware if the ACPI support is not activated despite apm=off.

  • pci=noacpi OR acpi=noirq

These parameters disable the PCI IRQ routing

  • pci=acpi

This parameter activates the PCI IRQ routing

  • acpi_irq_balance

ACPI is allowed to use PIC interrupts to minimize the common use of IRQs.

  • acpi_irq_nobalance

ACPI is not allowed to use PIC interrupts.

  • acpi=oldboot

Deactivates the ACPI system almost completely; only the components required for the boot process will be used.

  • acpi=ht

Deactivates the ACPI system almost completely; only the components required for hyper threading will be used.

  • noapic

Disable the "Advanced Programmable Interrupt Controller (APIC)".

  • nolapic

Disable the "local APIC".

  • apm=off OR noapm

Disable the Advanced Power Management.

  • irqpoll

Changes the way the kernel handles interrupt calls (set it to polling). Can be useful in case of hardware interrupt issues.

  • acpi.power_nocheck=1 OR acpi_osi=linux

Disable the check of power state or changes the OS compatibility reported to the BIOS. Necessary on some broken BIOSes to make temperature/fan control work.

On Ubuntu 13.04 and above, sleep and wake up works perfectly once you install NVIDIA's drivers. They don't work on the nouveau drivers.
