What I devised is to add a few lines to grub to disable the discrete graphics at the efi level: $ cat /etc/grub.d/10_linux I happen to have the exact same computer as you. one must still have OS X installed, which I haven't! This is really shitty, because it means that I have no chance to turn off the NVIDIA GPU. UPDATE: After reading lots of documentation I've came to the conclusion that this only is possible by using method 3 on Macbook Pro, i.e. Its a basically fresh installation of Ubuntu 14.04 without any tweaks worth mentioning.

The second method won't work either because I cannot install the propritary drivers, as described above.

It held for about 3 hours with Mac OS when doing similiar work. So I would like to turn the NVIDIA graphics off completely and only use the Intel integrated graphics instead, because the battery only holds for ~1,5 hours when doing office work since I installed Ubuntu. I've been told that this is because the NVIDIA driver doesn't support the special hardware characteristics of the Macbook. When I install the propritary NVIDIA driver (340.76), the system hangs when I start the X-server. You should use the uninstaller as it will clean up additional items.I have a Macbook Pro from 2010 that has NVIDIA graphics and Intel integrated agraphics: $ lspci|grep -i vgaĠ0:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)Ġ1:00.0 VGA compatible controller: NVIDIA Corporation GT216M (rev a2) Starting BOINC client version 7.0.35 for x86_64-apple-darwinģ - If I wanted to uninstall BOINC, can I throw it in the trash or I must use the uninstaller?

If you look at the start of the Event Log, you will see: The "x86" in the About dialog covers both i686 and x86_64. The number of processes will be the same whether or not a GPU is in use.Ģ - It says version 7.0.35 (x86) shouldn't be 圆4? BOINC 7.0.35 and later will cause the Mac to switch to the discrete graphics only when a project application (task) is running which uses the GPU.ġ - When discrete GPU is on, how many running processes should I see? 8 or 9? If you look in the Advanced View Tasks tab, the Status column for tasks which use the GPU will specify "+ 1 NVIDIA GPU".

(We are waiting for NVIDIA to make a change to their drivers so we can restore CUDA support.) Version 7.0.35 disables support for CUDA applications on BOINC, so only OpenCL project applications will use the discrete (NVIDIA) GPU. Intel HD Graphics is always on (i.e, no GPU computing), even when it's plugged.
