GPU crashes on Yosemite
I have a mid-2012 MacBook Pro and updated to OS X Yosemite a few weeks ago. Several times since then the GPU has crashed where I can still move the mouse cursor around the screen and listen to audio but everything else on the screen is unresponsive. I've only managed to remedy this by rebooting the machine.
Is there any way to prevent this happening?
The error logs have multiple instances similar to this:

I also experienced these crashes nearly every other day on my mid 2012 MBP.
This solved it for me:
Switch off "Automatic graphics switching" for Battery and Power Adapter
settings. This will increase overall power consumption but for me the
crashes have vanished.
Explanation: Mac Book Pros (and other Macs) quite usually come with two different GPUs. A low power and a high power GPU. OSX switches between these GPUs on demand. Since Yosemite this seems to be a problem for some people, because their systems are freezing occasionally. If your system suffers from hangs like described by the original poster, try this workaround until Apple fixes automatic GPU switching.
