I have a dual-boot Mac OS X 10.8 and Kubuntu 12.10 64x on my white MacBook from mid-2010 installed. (Model identifier: MacBook7,1.

I have upgraded my RAM from 2GB to 8GB, if that matters.) I have the proprietary NVIDIA drivers installed on my Kubuntu. Judging from the temperature monitor widget in Kubuntu, my temperature seems to be ~10℃ hotter compared to under Mac OS X. In Mac OS X I use. I'm comparing the CPU Core 0 and CPU Core 1 values in Kubuntu to the CPU Core 1 and CPU Core 2 values in Mac OS X. 10℃ more may be not a very big overheating disaster, but when I do really intense things on my computer (such as playing a while) my CPU is at ~70℃ on OSX, and when playing it a while on Kubuntu, my CPU is ~80℃. I worry that the higher temperature may shorten the lifetime of my laptop. I did some research and found out that it may be that I installed it in BIOS mode, which causes the heat.

That's the one with the Nvidia GeForce 9400M and the Nvidia GeForce 9600M GT. Using the Nvidia GeForce 9400M, as my default video card, seems to make my screen blinks. My best guess is that it's either a faulty chip on the logic board, RAM, or a driver problem. Nvidia GeForce 9400M makes my MacBook Pro screen blinks More Less. At idle, the new Mac mini uses less than 13 watts of power — 10 times less than a typical desktop PC, which makes it the most energy-efficient desktop computer in the world.

I can't install it in EFI mode, because the propietary NVidia drivers don't work then (already tried that, it gave a black screen). Does anyone know how to get the propietary NVidia drivers work in EFI mode? Edit: Ok, even if there isn't a way to use the proprietary nvidia drivers in EFI mode (doesn't seem like there is a way to do it, I'm not getting any answers), I would already be happy if the heating could be fixed in BIOS mode.

How can I at least fix the heating in BIOS mode? I tried putting this in my xorg.conf in the Device section to enable power saving: Option 'DPMS' '1' Option 'RegistryDwords' 'EnableBrightnessControl=1; PowerMizerEnable=0x1; PerfLevelSrc=0x2233; PowerMizerDefault=0x3'.but that didn't work. Oh, and I'm not using rEFIt by the way, could it be that? For me, booting Ubuntu in UEFI mode with the Nvidia drivers loaded, also always resulted in the well-known black screen when X was started. That was until yesterday! After running into some very promising info in about installing Windows 7 in UEFI mode on a Mac. Folks over there struggled with Windows 7's required int 10h legacy support and found out that in order to work around that, one can perform an unattended installation (because display doesn't work during install).

The crucial information to successfully boot Ubuntu in UEFI mode even with Nvidia drivers was that upon start of EFI boot (while handing over to grub), Apple's firmware does not actually activate the VGA card as PCI-E bus master. The Windows' guys explained how to circumvent this using an EFI shell which chainloads the Windows boot manager in order to at least run the setup in unattended mode.

And here is the good news: it's easy to do this in GRUB! In fact, I am right now typing this on a MacBook Pro 7,1 (mid-2010) running Ubuntu Vivid booted in UEFI mode ().

In order to provide the best platform for continued innovation, Jive no longer supports Internet Explorer 7. Attention, Internet Explorer User Announcement: Jive has discontinued support for Internet Explorer 7 and below. Free download adobe flash player for mac os x 10.5 8.

Jive will not function with this version of Internet Explorer.

However, it should be easy to run on or adapt this to any Linux distribution providing an EFI version of GRUB, e.g. Ubuntu 14.04.2 LTS. ~$ dmesg grep -i efi [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.19.0-15-generic.efi.signed root=UUID=7843c644-e6f4-4d64-9317-0b854cb524f2 ro quiet splash intremap=off acpi_osi=! Acpi_osi=Darwin nomodeset vt.handoff=7 [ 0.000000] efi: EFI v1.10 by Apple [ 0.000000] efi: ACPI=0xbf96a000 ACPI 2.0=0xbf96a014 SMBIOS=0xbf71a000 To cut the long story short, we have to set two PCI-E registers: one that enables bus-mastering on the video card and the other one enabling VGA support on the PCI-E bridge of the video card. So it has actually nothing to do with the Nvidia drivers and depending on the viewpoint, not even with Apple's outdated/crippled/you name it EFI implementation. This is how I solved it.
