I have been successful with GPU pass through on windows and osx, but an having trouble with Linux. I have tried to install a couple distros with different results. Most recently I tried Pinguy OS (Ubuntu derivative), and the GPU passed through for the live installer, but wouldn't boot afterwards. I tried Linux Mint and it can see the GPU, but will not display anything. When trying to install drivers from the amd website, it complained about fglrx-core dependencies. I also tried netrunner but can't remember the error.

 

Has anyone been successful with passing a GPU through to a linux host? Oddly enough I can pass the same GPU to a xbmcbuntu just fine. Any steps I should follow in order to get it right?

A quick clarification on terminology before we continue.  You're not talking about passing through to a Linux host, but rather, a Linux guest.  A guest is a virtual machine.  The host is unRAID Server OS itself.  So all of that said, now let's cover your question a little deeper.

 

Passing through a GPU to a guest VM requires that the guest's kernel have drivers for the device in question.  As various flavors of Linux operating systems use different kernel versions of their own, the actual drivers that will get supplied for the device in question may vary, and therefore, alter your experience in passing through the GPU.  Lastly, some GPUs behave better than others when being passed through, so your experience with various GPUs may vary (even from the same manufacturer).
